Abstract
Experimental data are described in the paper, which demonstrate the possibility of a simultaneous extraction of acid and basic substances and of ampholytes from biological liquid for their subsequent gas-chromatography screening by means of a mass-selective detector.
摘要
本文描述了实验数据，这些数据证明了从生物液体中同时提取酸性和碱性物质以及两性电解质，以便随后通过质量选择检测器进行气相色谱筛选的可能性。
