Using a simple injection adapter of our own design, the tetrahydrocannabinol content of marlhuana was determined by gas chromatography. The injection method obviates the need for preliminary extractions and allows analyses to be conducted on milligram quantities in less than thirty minutes.
使用我们自己设计的简单进样适配器,通过气相色谱法测定了大麻中的四氢大麻酚含量。这种进样方法无需进行预萃取,并且能够在不到30分钟的时间内对毫克量的样品进行分析。
