Water, methanol, chloroform and their mixtures were used as mobile phases and the elution behaviours of polyethylene glycols (PEG) and polystyrenes (PS) on a hydrophobic poly(vinyl alcohol) column were investigated. The column efficiency was not affected by variation of the mobile phase. Samples ...
甲基丁炔醇,也被称为3-甲基2-丁炔醇(3-Methyl-2-butynol)、2,2-二甲基乙炔甲醇(2,2-Dimethylethynylmethanol)、2,2-二甲基丙炔醇(2,2-Dimethylpropargyl alcohol)、2-甲基-2-羟基-3-丁炔(2-methyl-2-hydroxy-3-butyne)等,是一种有机化合物。其分子式为C5H8O,结构式为HC≡CC(CH3...
Reaction mixtures were centrifuged and diluted (10x) to a CopC concentration of 10 µM by methanol/water (50/50) in formic acid (0.1%) for ESI-MS under denaturing conditions or by ammonium formate (50mM; pH 7.0) under non- denaturing conditions immediately prior to analysis. The sample...
