test substance. In chromatography science‚ the solvent is called the mobile phase or the carrier fluid and the medium is called the stationary phase. There are four main types of chromatography; these are Liquid Chromatography‚ Gas Chromatography‚ Thin-Layer Chromatography and Paper Chromatography. Chromatography is used extensively in forensics‚ from analyzing body fluids for the presence of illicit drugs‚ to fiber analysis‚ blood analysis from a crime scene‚ and at airports to detect residue from explosives

Date Submitted: January 6‚ 2014 Experiment 4: Extraction and Chromatic Separation of Plant Pigments from Tomato Paste ABSTRACT In column chromatography a mixture is dissolved in a solvent and poured over a column of solid adsorbent then eluted with the same or a different solvent. This method is often used for preparative purposes; when a relatively large amount of the mixture and the components need to be isolated.

colored dyes go into your favorite candies? Chromatography can solve that for you. Chromatography is a separation technique used by scientists for separating both organic and inorganic compounds. There are four different types of chromatography: thin layer‚ liquid‚ gas‚ and paper‚ but for this lab paper chromatography will be used. Who invented chromatography? A Russian botanist named Mikhail Semyonovich Tsvet invented chromatography in 1901 while doing research on plant pigments. Why is chromatography

Chromatography refers to a set of laboratory methods used in separating as well as purifying biomolecules. A variety of chromatography techniques exist‚ and all depend on the interaction between a stationary and a mobile state. Two types of chromatography methods were examined in this investigation. First‚ ion-exchange chromatography was used. This method separates ions and polar molecules based on their affinity to the ion exchanger [2]. Specifically‚ cation-exchange chromatography was performed
