本文报道采用硅胶预柱快速分离干扰杂质后用CGC-FID法测定尿中多胺。最低极限可测到1nmol。该法快速、灵敏、重现性好、所得回收率高、可用于临床诊断。
This paper reports the determination of polyamines in urine by CGC-FID after silica gel precolumn is used to separate the interference impurities. The lowest limit can be measured to 1nmol. The method is fast, sensitive and reproducible, and the recovery rate is high, which can be used for clinical diagnosis.
