How does a solvent/detergent effect the release of pigments from beetroot cells? Describe the properties that influence the movement of pigment molecules in paper chromatography. What is the purpose of the paper chromatography experiment? a.To separate photosynthetic pigments b.To see which...
Fractional distillation is used to separate mixtures using which physical property? What piece(s) of glassware distinguish a simple distillation setup from a fractional distillation setup? What is simple distillation useful for? Explain why the boiling points of the components of a mixture should diffe...
As stated earlier, chromatography is used in laboratories to separate or quantify the mixtures of organic compounds. For this purpose, it utilises the polarity difference in molecules, and the compounds get divided based on their affinity towards the stationary phase. There is also one mobile phase...
The latter is usually done by high-performance liquid chromatography (HPLC) and mass spectroscopy (MS) to separate the peptide fragments according to their masses. The mass spectra often show patterns that belie particular PTMs—for example, multiple mass shifts of 162 kDa for glycosylation sites,...

To start, the researchers separated and identified the volatile compounds in each odor with gas chromatography. "A complex mixture like urine has at least a hundred separate compounds in it," Lin said. They analyzed scents as diverse as peanut butter, coffee and fresh bobcat urine shipped to ...
There is one more subtle thing about elutant mixtures. It is sometimes possible to separate overlapping spots while trying different mixtures of similar strength. For example if 30 : 70 ethylacetate : hexane produces Rf1 = 0.30 and Rf2=0.30 (which means spots are overlapping) for a some ...

Describe how to separate water from a mixture of water, alcohol and sand. What makes the following two mixtures different? Discuss with an example: 1. Homogeneous mixture. \\ 2. Heterogeneous mixture. Describe how the separation of mixture is done using ...
Chromatography is a key technique used to separate and quantify different compounds. How does gas chromatography work? When a paper chromatography was completed on a three-component mixture, only two spots appeared on the paper. What conditions or para...
