报告了气相色谱法测定粮食中T-2毒素的方法。采用三氯甲烷和无水乙醇提取,正已烷除脂,活性炭-中性氧化铝柱甲醇水梯度洗脱,TBT衍生。结果表明,该法简单、省时、回收率高(80.0%~84.7%),成本低,最低检出量为10ng,线性范围为30-2000ng。
A method for the determination of T-2 toxins in food by gas chromatography was reported. Extraction with trichloromethane and absolute ethanol, n-hexane degreasing, activated carbon - neutral alumina column methanol gradient elution, TBT derived. The results show that the method is simple, time-saving, high recovery (80.0% ~ 84.7%), low cost, the lowest detection rate of 10ng, linear range of 30-2000ng.
