why water, methanol, ethanol ets solvents are used in UV SPECTRIPHOTOMETER for blank reading ?
7 29018How much area of methanol or other solvent are acceptable in blank (Diluent) of Gas chromatography.
2 9155In UV-VIS spectrophotometer:My diluent is methanol even though i corrected base line for methanol,In my sample scan i found methanol peak.what is the reason?
2 10352mixed 1.0 ml of methanol and 1.0 ml of toluene and injected in gas chromatography.will you prove that both solvents are in the ratio 1:1(not by area normalization)
1 3860Two methanol-water mixtures are contained in separate tanks. The first mixture contains 40.0 wt % methanol and the second contains 70.0 wt % methanol. If 200 kg of the first mixture is combined with 150 kg of the second, what are the mass and composition of the product? The symbol of weight percent is wt %.
