Paper chromatography Presented by – Miss. Shruti Vilas Kharat. SYBSc / FS13164 History- Paper Chromatography (PC) was first introduced by German scientist Christian Friedrich Schonbein (1865). PC is considered to be the simplest and most widely used of the chromatographic techniques because of its applicability to isolation‚ identification and quantitative determination of organic and inorganic compounds. Definition- Paper chromatography is an analytical method technique for separating and

is our project. If our markers will ran out of ink‚ we don’t need to buy a new one‚ because all we have to do is use seaweed and mix it with the other materials stated in Chapter 2. Because of this project‚ we can save more and spend less. Statement of the Problem: Most people in school‚ particularly the students and the teachers‚ needs markers for our reports‚ projects‚ and etc. But one of the problems in using markers is they ran out of ink easily. Because of that‚ we need to buy again a

How to Make Ink from Alugbati Things You’ll Need: • Fresh fruit of alugbati • Mortar and pestle • Strainer • Bowl • 3 tbsp. vinegar • 1 tbsp. salt • 2 tbsp. rubbing alcohol • 1 tbsp. iodine • Bottle Writing ink can be made from many natural sources‚ such as the fruit juice of the alugbati plant. Alugbati‚ known in the U.S. as Malabar spinach‚ is commonly grown for its soft‚ spinach-like leaves and shoots. Alugbati is of African and East Asian origin. The juice of the fruits was reportedly

Magnetic ink is very useful because it is readable both by humans and by specialized equipment. It is one of the components that makes it possible to process personal checks securely‚ quickly and accurately. Magnetic ink character recognition (MICR) is a character-recognition technology used mainly by the banking industry to ease the processing and clearance of cheques and other documents. The MICR encoding‚ called the MICR line‚ is at the bottom of cheques and other vouchers and typically includes

Gas Chromatography Purpose: The purpose of the gas chromatography lab is to find out how different substances interact with the surface of a solid. Chromatography is a separation technique that depends on the relative distribution of the components of a mixture between a mobile phase and a solid stationary phase. Chromatography measures the tendency of a substance to interact with the surface of a solid or to remain in a mobile phase. When doing a chromatography lab the mobile phase has to

OBJECTIVE The purpose of this experiment is to analyze mixtures of compounds prior to‚ during and after a separation scheme. This experiment also allows monitoring reactions of organic molecules‚ and determines the identity of a mixture of compounds. STRUCTURES AND PHYSICAL PROPERTIES OF REACTANTS [1] SOLVENTS | a.

Homemade ink 1. Black Ink: There are several ways to make black ink. Here’s an easy one: take one egg yolk‚ ½ teaspoon lamp black‚ ½ cup honey and one teaspoon gum arabic. Lamp black is available commercially or you can make it yourself by holding a plate or any receptacle over a lit candle - it will take some time to collect half a teaspoon though. Mix all of the ingredients to make a thick paste and add enough water to this paste to dilute it so that it flows easily as a fluid. 2. Gall-Iron

Chromatographic Separation of Sodium Fluorescein and Methylene Blue In this two-part lab the students will: • Learn the techniques associated with thin layer and column chromatography. • Determine the effects of the stationary phase in separating a mixture by chromatography. • Determine the effects of the mobile phase in separating a mixture by chromatography. • Conduct a separation using column chromatography. In the first week‚ the students will determine the best solvent system for separating

Introduction Chromatography is a technique used to separate a mixture into its individual components. In this experiment‚ chromatography is done by using a thin layer chromatography (TLC) plate and filter paper. The word ‘chromatography’ itself means the separation of colours. However‚ nowadays‚ both coloured and colourless compound are used in chromatography by various methods. In chromatography‚ the separation process of mixture is mainly based upon the polarity and molecular weight of sample
