随着科学技术的发展,新的有机物大量产生,在这些有机物为人类带来便利的同时也对环境造成了污染。有机物经过降解,以极低的含量存在于大自然中。评价这些环境污染物的含量,目前只有色谱分析才能完成。在色谱分析中,大部分的原始样品不适合用仪器直接分析测定,需要对原始样品进行一些处理,制备成适合于仪器分析的样品。样品处理在色谱分析过程中是一个既耗时、又极易引起误差的环节,是色谱分析技术发展的一个重
With the development of science and technology, a large number of new organic substances are produced, which bring pollution to the environment while these organic substances bring convenience to human beings. Organic matter is degraded and exists in nature at very low levels. Evaluation of the content of these environmental pollutants, the current chromatographic analysis can be completed. In chromatographic analysis, most of the original samples are not suitable for direct analysis by instruments. Some samples of raw samples need to be processed to prepare samples suitable for instrumental analysis. Sample processing is a time-consuming and error-prone part of the chromatographic analysis and a major development of chromatographic techniques
