Chromatography – Types or Techniques Ravina Pandita Department of Biotechnology, Deenbandhu Chhotu Ram University of Science and Technology, Murthal, India Email: ravinapandita@gmail.com Abstract: Chromatography is a technique which is used to separate different type of mixtures on the basis of some specific property. The property may be charge, size, hydrophobicity etc. It can be used to prepare small quantities of material by analysing them and purifying them. It is the most widespread and versatile technique used for separation of small quantities of material. This review paper after taking into consideration some major studies provides a brief knowledge about Chromatography, steps involved in chromatography and various techniques of chromatography by separation techniques. Four types of chromatography is discussed, in which separation of mixture is done on charge, size, hydrophobicity and pressure.These four types are most commonly used for separation of biotechnology products at a large scale. Chromatography is a vast topic, through this paper we focus on just the part related to separation of small quantities of mixtures. Study of chromatography on the whole is beyond relevance here. Keywords: Chromatography, Separation, Mixtures, Techniques, Types, Molecules, HPLC, Charge, Size, Hydrophobicity, Purification Introduction: Mixture consists of different materials which move with different speeds thus causing them to separate from each other.

The various components of a sample mixture are known as analytes. Chromatography was originally used to separate the various molecules that make up plant pigmentation. Because these components, carotenes, chlorophyll, and xanthophylls, are different colors, the separation of them isRead MoreLab 04 - Chromatography and Ionic vs Covalent Bonds1417 Words   |  6 PagesStudent ID: 4593119 Date: 7 Dec 2014 Course and Section Number: SCIN131 A004 Fall 14 Lesson 4 Lab: Chromatography and Ionic versus Covalent Bonds PART 1 Begin by viewing the following Thinkwell video 15.1.3   CIA Demonstration: Chromatography After you watch the above video, answer the questions below in sufficient detail: (a) (3 pts.)

Chromatography is the term for the laboratory techniques used in the separation of mixtures. The mixture is dissolved in a fluid, which is called the mobile phase. The mobile phase carries the mixture through a structure holding another material, which is called the stationary phase. The various components of the mixture travel at different speeds, which causes them to separate. Chromatography is technique generally used for chemical analysis in scientificRead MoreInvestigating The Substances Of Water Chromatography1350 Words   |  6 Pageswhich toxic ions might be present in a sample. Chromatography is one of the first tools used in such situations. In this technique, many types of mixtures can be separated into the component pure substances; by comparison to a standard sample, each component substance can also be tentatively identified. Many varieties of chromatography exist, each one designed to separate specific types of mixtures. The common feature of each type of chromatog raphy is that a mobile phase (a liquid or gas) is pushedRead MoreExperiment Chromatography : Using The Concentration Of Compounds And Helps Identify The Substances Within It1417 Words   |  6 PagesChromatography Different types of Chromatography Paper chromatography Paper chromatography is a method of testing the purity of compounds and helps identify the substances within it. Using the paper chromatography is a useful and simple technique as it is relatively quick and requires small quantities of material. Paper chromatography separates colours, this also happens in the thin layer chromatography. Using the paper chromatography method, substances the distribution between stationary phase andRead MoreTechniques Used By Analytical Chemist For The Creation Of Ions From A Sample1454 Words   |  6 Pages Electrospray is the technique that is used by analytical chemist for the creation of ions from a sample. The technique uses electricity to form an exceptionally fine liquid aerosol. Other techniques that were used before electrospray used gas to form these aerosols for analyses. Electrospray is particularly useful over using gas because it is a soft ionization technique. Soft ionization techniques ionize the sample with minor fragmentation of the molecule, giving an observable molecular ion forRead MoreThe Light Energy Absorbed By Colored Compounds1429 Words   |  6 PagesExperiment 4.1, dilutions of PNP are prepared, and the Bradford Method was used to measure protein concentration. There are different types of chromatography, and we would be using gel filtration and affinity. Chromatography is defined as the separation of molecules based on properties such as molecular mass, charges or solubility. In Experiment 5.1, gel filtration chromatography was used to separate molecules based on their molecular mass. The stationary phase in the column contains tiny pores, those thatRead MoreDetection or Identification of Trace Amounts of Explosives1624 Words   |  6 PagesThe detection and/or identification of trace amounts of explosives.
