What is chromatography- Chromatography is the separation of mixture by passing it in solution or suspension or as vapor. It’s a technique for separating mixtures into the components this needs to happen in order to do the 4 things analyze‚identify‚purify‚quantify. Many scientist use this to do the 4 steps. When analyzing its used to examine the mixture and to find out the relation with one another. In purifying you need to seperate or take away and put it by itself for further study. In identifying

Plant Pigment Lab Question: What pigments are present in Red Wandering Jews? Background: A leaf is filled with many pigments. The pigments are usually masked by the prevalence of the green chlorophyll. Anothocyanin(red or purple)‚ carotene(orange)‚ and xanthrophyll(yellow) are found in different proportions in different leaves. Leaf pigments can be separated by using paper chromatography. Paper chromatography is a technique that extracts pigments into a paper filter called chromatogram. What are

CHAPTER 6 MECHANICAL-PHYSICAL SEPARATION PROCESSES Introduction Separation Processes Many chemical processes materials and biological substances occur as mixtures of different components in the gas‚ liquid‚ or solid phase. In order to separate or remove one or more of the component from its original mixture‚ it must be contacted with another phase. The two-phase pair can be gas-liquid‚ gas-solid‚ liquid‚ or liquid-solid. Absorption When the two contacting phases are a gas and a liquid

Component seeks to separate‚ identify‚ quantify and analyze the active component found in Biogesic®‚ which may be useful for public awareness despite its wide acceptance and availability in the market. Furthermore‚ this study applies thin layer chromatography (TLC) technique since it is the simplest‚ cheapest yet most effective approach in terms to the study’s objectives. The TLC method implies Rf (Rate of flow) values where it is given by the distance from origin to center of subtance spot over the
