When working in a lab, scientists often need to identify different molecules that are present in a sample they are studying. There are many ways to identify unknown molecules/chemicals in a sample. The method you will be using today is called Paper Chromatography and consists of 2 steps. First, you will separate the unknown chemicals and then you will identify them. This process can also be applied to the food we eat everyday.When you eat food or drink liquids you…...
Gas Chromatography Lab Report Essays
Gas chromatography separates the component of a sample based on the ease with which they evaporate into a gas, also known as the volatility. The chemical mixture being analyzed is injected into the injection point and carried through the instrument by an inert gas, in this case Helium. The temperature of the injection point is approximately ICC and the oven temperature is around ICC. There is a column in the oven that makes it Seibel to separate the chemicals based…...

Salt And Sand Separation Lab Report
Evaporation is a process where two liquids or solid mixed into a liquid can be separated. To separate two liquids mixed together, the liquid is boiled over a Bunsen burner until one liquid is completely evaporated. To separate a solid within a liquid, the liquid is completely evaporated and a solid will remain, which is called a residue. Procedure/Data: 1. Preheat a clean evaporating dish for 5 minutes; then cool and mass the dish. Mass of empty dish: 28. Egg…...
Thin Layer Chromatography Lab Report
Chromatography works on the principle that different impounds will have different solubility and adsorption to the two different phases between which are to be partitioned. Thin Layer Chromatography (TTL) is a solid-liquid technique. The mixture is observed when it is in two different phase; a solid (stationary phase) and a liquid (moving phase). Thin Layer Chromatography (TTL) is a technique which is sensitive, cheap and fast. A thin layer chromatograph plate is used to identify drug component under LIVE. It…...
