| Abstract: | The freeze-drying of biological material, which is to be quantitatively analyzed (micro-amount level) for compounds of low or intermediate molecular weight, should be either omitted or handled under strict control. This is because compounds such as amino acids, sugars, flavonoids, glycosides, coenzymes, peptides, etc., might be removed from concentrates and (or) the ground biological material by the high vacuum. |
