本文报道了用高效液相色谱的方法,测定涤纶纤维上的3种分散染料。以甲醇—水—乙酸(70:30:1,V/V)为流动相,测得结果回收率为104.7～107.8%,CV%为0.070～1.8,最小检出量为2.560～7.419ng。
This paper reports the determination of three disperse dyes on polyester fibers by high performance liquid chromatography. The recoveries were 104.7 ~ 107.8% with methanol-water-acetic acid (70: 30: 1, V / V) as mobile phase and the CV% was 0.070 ~ 1.8. The minimum detectable amount was 2.560 ~ 7.419ng.
