一、气相色谱法一般介绍气相色谱法是近廿年来迅速发展起来的一种新型的分离分析技术.由于它具有分离效能高、分析速度快、样品用量少等特点,因而已被广泛用来解决石油、石油化学、化工、有机合成、医药卫生、食品等工业生产、科学研究和生产控制方面的分析问题.在不断丰富、发展和提高的过程中,已逐渐形成了一个专门的学科领域——气相色谱学. First, the general introduction of gas chromatography Gas chromatography is the rapid development in recent twenty years, a new separation and analysis technology due to its high separation efficiency, high speed, low sample consumption and other characteristics, which has been widely used Solve the analytical problems in petroleum, petrochemical, chemical, organic synthesis, medicine and health, food industrial production, scientific research and production control, etc. In the course of continuous enrichment, development and improvement, a specialized discipline area has gradually been formed - Gas chromatography.
