When the incident light strikes on the matter it can either be absorbed, reflected, or transmitted. The atomic excitation occurs due to the absorbance of radiations in UV Vis range, which refers to the transition of molecules from the ground state to an excited state. Before an atom can change excitation states, it must absorb sufficient radiation for electrons to move into higher molecular orbits. If there is a Shorter bandgap between electrons then there will be the absorption of shorter wavelengths of light. A UV-Vis spectrophotometer measures the intensity of light transmitted through a sample compared to a reference measurement of the incident light source. The amount of light absorbed is directly proportional to the concentration of the sample and the distance the light travels through the sample. Therefore, UV-Vis spectrophotometers are able to determine the concentration of specific analytes in a microvolume by controlling the Wavelengths and path length. Chapter 2 Working principle of Spectrophotometer The working principle of the Spectrophotometer is based upon Beer-Lambert’s law, this law stated as the amount of light absorbed by a color solution is directly proportional to the concentration of the solution and the path length. Mathematically, A ∝ cl Where, A = Absorbance / Optical density of solution c = Concentration of solution l = Path length or, A = ∈cl ∈ = Absorption coefficient Chapter 3 Types of UV Vis Spectro photometer TYPES OF SPECTROPHOTOMETER Following are the two different types of spectrometer Single beam spectrophotometer Double beam spectrophotometer Single Beam Spectrophotometer: This type of spectrophotometer works between 325 nm to 1000nm wavelength using a single beam of light. Light travels in uni-direction and read the blank and test solution same. Double Beam Spectrophotometer: This type of spectrophotometer works between 185 nm to 1000 nm wavelength. This instrument splits the light from the Monochromator into two beams. One beam is used for reference and the other for sample reading. It eliminates the error which occurs due to fluctuations in the light output and the sensitivity of the detector. Chapter 4 Main parts of UV Vis Spectro photometer MAIN PARTS OF SPECTROPHOTOMETER There are following Seven different parts of spectrophotometer Light source: In spectrophotometer different sources of light are used to produce light of different wavelengths. Tungsten lamps common source of light used in the spectrophotometer for the visible spectrum. Hydrogen lamp and the deuterium lamp for Ultraviolet radiation. Nernst filament or globaris is the most satisfactory source of IR radiation. Monochromator: The main function of a monochromator is to separate the color components of light. To select the particular wavelength, prism or diffraction grating is used to split the light from the light source Sample holder: Test tubes or Cuvettes are used to hold the colored solutions. They are made up of glass at a visible wavelength. Beam splitter: It is present only in a double beam spectrophotometer. It is used to split the single beam of light coming from the light source into two beams. Mirror: It is also present only in a double beam spectrophotometer. It is used in the right direction to the split light from the beam splitter. Photodetector system: When light falls on the detector system, an electric current is generated that reflects the galvanometer reading. Measuring device: The current from the detector is fed to the galvanometer. The reading on the meter is directly proportional to the intensity of light.

These components aid to seal final products in the pockets or cavities. By doing several mechanical steps, it forms pockets or cavities on forming material fills the pockets or cavities and covers them with a fitting material. Hence it assists with setting up the medicine and nutraceutical items for safe conveyance. Reading further this guide, you will learn the features of this machine, which can enhance productivity in Chapter 4. CHAPTER 2 Working principle of Blister packing machine You have taken the blister packing machine overview in Chapter 1. Now after reading you must be thinking that How does this machine work? How various parts of this machine work together? Well, that is what you are going to learn in this chapter. For your ease, only the general working principle is covered in this guide. Now let’s start! The machine works on the rotary sealing principle. This film is moving ahead from a reel and enters in a blister forming unit where the film is softened by heat and forms blisters, then the filling process starts, and after filling the package in blisters, sealing part of the machine sealed the blisters. At the end printing of batch number, start in the printing section and the blistering process complete. The above summary of the working principle consists of 06 steps. Let us briefly go through all these steps. Step 1: Turning on the machine As you turn on the machine, you will notice that feeding rollers and other parts of the machine start moving. At this stage, the forming film moves to the first stage. Step 2: Heating Station Processing Thermoforming blister packing machine includes this heat-processing unit. At this stage, the machine starts to heat the forming film to the desired temperature until it is soft enough to form cavities. The set temperature is always base on the type of forming material you are using. Step 3: Film Cavities Forming In the third step, two mechanisms are used to form desire cavities i.e. compressed air or die plates. These cavities form the blister packing machine will cool down these cavities to give them a rigid shape. Step 4: Product filling and Empty cavities checking In this stage, the blister packing machine will fill the cavities with the final product. The filling step will be either manual or automatic, which totally depends on the type of machine you have selected. You know that aluminum is opaque (you cannot see through) in nature so it is mandatory to look for empty cavities. Therefore, this empty pocket detector is placed at the end of the filling station. Step 5: Blister Sealing At this stage, the filled cavities are ready for sealing. To seal the blister lidding material is used. It is very important for a machine that lidding material is in place timely as forming film reaches the sealing station. Moving further the lidding material cover the fill cavities. The heat-sealing station comes next which seals the product in the cavities. To make sure that sealing is up to the mark both high temperature and pressure are applied. Step 6: Printing & trimming of product This is the last step of blister packing. The seal pack moves to the next stage i.e. printing station. At this point machine, emboss the set message in it. After that machine, push forward the blister pack to the cutting or trimming station. This trimmer trims it into desire units. The leftover lidding and forming material is rolled into a scrap collector. CHAPTER 3: Types of blister packing machine Dear readers, it is very important for you to know about various types of blister packing machines. As you have already study about its overview and its working principle in chapter 1 and 2 now we will discuss its various types. It is also very important for you to know every machine’s technical specifications which you will read in Chapter 12. Without wasting any time now let us dig into it. There are several ways to classify these machines. However, in this guide, you will learn about the types based on their operation and the packing material used. There are the following three types of packing machines based on their operation Thermoforming Blister Packing Machine Thermoforming

HPLC Overview Working Principle of HPLC Types of HPLC based on Operational Method Main Parts of HPLC Quality Parameters Checking of HPLC Trouble Shooting of Common Problems, which occurs during Operation. HPLC Applications Merits and demerits of HPLC Famous brands of HPLC High Performance Liquid Chromatography (HPLC) In this chapter you are going to learn about chromatography and its types, its major concern is about High performance liquid chromatography (HPLC). Chromatography is a separating technique, in which separation is done on the basis of the structure of the molecule in two-phase (i.e. Mobile phase and Stationary phase) The stationary phase is a solid or a liquid material packed in a column and a mobile phase is a liquid or a gas that flows through the stationary phase. The mobile phase flows through the stationary phase and carries the components of the mixture with it. The component of a mixture, which shows stronger interactions with the stationary phase, will retain in the stationary phase while the component of the mixture, which dissolves in the mobile phase, will move with it and elute first. HPLC stands for High performance Liquid chromatography or high-pressure liquid chromatography as it uses a high-pressure liquid mobile phase than gases used in Gas chromatography. HPLC is an analytical technique used for the separation of components of the organic mixture of compounds when such compounds are nonvolatile, thermally unstable, and have relatively high molecular weights. Working principle of HPLC In the previous chapter you learn about the introduction of HPLC, now in this chapter, you will learn about the working principle of HPLC. The working principle of HPLC is based on the distribution of the sample between a mobile phase (eluent) and a stationary phase (packing material of the column). Molecule retarded in stationary phase and separate on the basis of difference in retention time. The component of a mixture which retain in the stationary phase elute later, as compared to that which dissolves in the mobile phase. Types of HPLC This section will help you to learn different types of HPLC. Types of HPLC, Based on mode of separation 1. Normal Phase HPLC In this type of HPLC, components are separated on the basis of polarity. In the Normal phase HPLC, the polar stationary phase is used with the non-polar mobile phase. The stationary phase is usually silica and the mobile phase is Hexane, Methylene Chloride, Chloroform, Diethyl ether, and mixtures of these. As the Stationary phase is polar in normal phase HPLC therefore, the Retention time of Polar samples on the polar surface of the column is longer and they elute later than less polar materials. 2. Reverse Phase HPLC In this type of HPLC, the stationary phase is non-polar in nature, while the mobile phase is a polar liquid i.e. mixtures of water and Methanol or Acetonitrile. It works on the principle of hydrophobic interactions hence retention time of non-polar material is longer than polar material. Note: Reverse phase chromatography is more commonly used as drugs are usually Hydrophilic. 3. Size-exclusion HPLC In this type of HPLC, the Column used is filled with a material having control pore size and separate the components on the basis of size. Large size molecules pass through the column while small size molecules penetrate inside the pores of the packing material and due to having large retention time elute later. 4. Ion-Exchange HPLC In this type of HPLC, The stationary phase has a charged surface of opposite charge to the sample ions. The sample with a strong charge will be attracted to the ionic surface, due to this attraction its retention time will increase and elute later. The mobile phase is an aqueous buffer, where both pH and ionic strength are used to control elution time. (Learn) Types of HPLC Based on Elution technique: Isocratic Elution: A separation in which the composition of the mobile phase remains the same throughout the procedure. In isocratic elution, peak width increases due to high retention time which directly relates to the number of theoretical plates. This leads to the disadvantage that late eluting peaks become broad and flat. Gradient Elution: A separation in which the composition of the mobile phase is changed during the procedure. Gradient elution decreases the retention of later-eluting components and gives narrow peaks and also improves the peak shape and height. Main parts of HPLC Now it is the time to learn about some main parts of HPLC. The components of HPLC are following, 1. Solvent Reservoir The mobile phase contained in a glass reservoir. In HPLC, the mobile phase is normally a mixture of polar and non-polar liquid components whose compositions are changed by changing the composition of the sample. 2. Pump A pump sucks the mobile phase from the solvent reservoir and forces it to pass through the system’s column and detector. The pressure of the pump depends on a number of factors including column dimensions, the particle size of the stationary phase, the
