吩噻嗪类安眠镇静药物易受光、热分解,气相色谱分析法受一定限制。而采用反相离子对液相色谱技术,使七种常见吩噻嗪类药物得到较好的分离。使用紫外及荧光分光光度计测定,可作为血、尿中此类药物的快速定性、定量分析方法之一。本法已在刑事中毒案件与临床抡救化验中应用。 Phenothiazines sleep hypnotic drugs susceptible to light, thermal decomposition, gas chromatography by a certain limit. The use of reversed-phase ion-pair liquid chromatography technology, so that the seven common phenothiazines get better separation. Using UV and fluorescence spectrophotometer determination, can be used as blood, urine of such drugs rapid qualitative and quantitative analysis method. This Law has been applied in criminal poisoning cases and clinical paralysis tests.
