WebJan 1, 2014 · While methanol and water will extract the polar metabolites from a sample, non-polar metabolites must be separated with a non-polar solvent. Therefore, we use chloroform [4] with the methanol/water mixture to separate the polar and non-polar metabolites efficiently. Adherent cells quenched with methanol and water are scraped … WebChloroform-methanol mixture. 2 : 1 by volume. Pure solvents upper phase and pure solvenk lower phase. Chloroform, methanol, and water are mixed in a separatory funnel in the proportions 8: 4: 3 by volume. When the mixture is allowed to stand, a biphasic system is obtained. The two phases are collected separately and stored in glass bottles. It ... build hacks minecraft eystreem
