近二十年来,用气相色谱法分析氨基酸,己经进行了大量的工作。在农业、生物、地球和行星科学等领域内,采用气相色谱法分析氨基酸日益广泛。本法有分析速度快、灵敏度高等特点,仪器的成本也比氨基酸自动分析器低。现在,采用气相色谱法,不超过一小时就可以对二十种蛋白氨基酸作一次全分析。用氢火焰离子化检测器时,灵敏度可达10~(-10)克分子。如果采用电子捕获检测器,灵敏度还可以提高
In the past two decades, a great deal of work has been done on the analysis of amino acids by gas chromatography. In the fields of agriculture, biology, earth and planetary science, the analysis of amino acids by gas chromatography is becoming more widespread. This method has the advantages of fast analysis, high sensitivity, the cost of the instrument is also lower than the automatic amino acid analyzer. Now twenty-eight protein amino acids can be fully analyzed in less than one hour using gas chromatography. With hydrogen flame ionization detector, the sensitivity of up to 10 ~ (-10) mole. Sensitivity can also be increased if electron capture detectors are used
