Is it used for solids, liquids, or gases? Explain. What is the term for chromatography in which the eluent is forced through the stationary phase by high pressure applied by a pump? Define the term viscosity, and describe how it depends on the strength of the intermolecular forces. What...
Column chromatography is a laboratory technique that separates and isolates compounds and active ingredients. It uses a stationary phase such as silica and alumina to separate the components of the mobile phase. The technique utilizes the principle of affinity of the components to ...
Narrowly polydisperse poly-l-lysines of different degrees of polymerization (from 20 up to 鈮 400) having a counter-ion similar to the eluent are analyzed as model compounds. By comparing the average degree of polymerization obtained by SEC-MALLS with those derived independently from NMR/...
What is the mobile phase for this lab? The stationary phase? 3. What is the effect of changing the mobile phase's polarity on a column chromatography compared to a thin layer chromatography? Could you tell from the TLC on the effect on the separation from column chromatography? In Thin Lay...
A modern chemical laboratory has a variety of equipment that is used to assist in performing a chemical reaction or other type of experiment. Examples include an analytical balance to measure the mass of a solid sample, an electronic thermometer to measure the temperature of a solution ...
Chromatography relies on the interaction of molecules with both the mobile phase, or eluent, and the stationary phase found in the column. Stronger interactions with the latter will cause longer elution times.Answer and Explanation: Become a member and unlock all Study Answers Start today. Try it...
The phase boundaries and the grain boundaries are present in the polymineralic rock. This rock is composed of a number of different minerals and they are very abundant on earth. Answer and Explanation:1 Grain boundaries are used to separate the grain of the same phase that has a differ...
What properties should the stationary phase liquid for gas chromatography possess?Question:What properties should the stationary phase liquid for gas chromatography possess?Chromatography:It is a widely used method for segregating components in the sample mixture. Two phases, stationary and...
Mass spectrometry is a technique used in analytical chemistry to identify and study the structure and composition of molecules using the mass and charge of the molecules. The mass and charge are related to each other in a ratio. That means that the molecule has ...
