结果表明,方法的检出限为0.318nmol/cig,相对标准偏差(RSD)为3.5%～9.7%;利用TEMPO-9-AC捕集体系鉴别出了10种碳中心自由基;对5种代表性卷烟烟气中的碳中心自由基进行了定量计算,获得了它们在主流烟气中碳中心自由基的含量数据,并发现碳中心自由基总量与焦油释放量之间具有高度的相关性。 chrom-china.com | The results showed that the 10 carbon-centred radicalswere detected in the mainstream cigarette smoke, and the totalcarbon-centred radicals concentrations for 1R5F, 3R4F, CM6, and two Virginia type cigarettes, were 52.5 nmol/cig, 214.6 nmol/cig, 424.1 nmol/cig, 68.6 nmol/cig, and 334.2 nmol/cig, respectively; and there was positive relation between the concentrations of the total amount of carbon-centred radicals and the tar amounts in the mainstream cigarette smoke. chrom-china.com |
结果表明,盐离子存在的条件下适配体与凝血酶的亲和力降低,不利于两者的结合;人血清溶液中,凝血酶浓度在0.25～10nmol/L范围内与复合物峰面积具有良好的线性相关性(r20.991),检出限(S/N3)为55.6 pmol/L;精密度和回收率测定结果均能满足分析的要求。 chrom-china.com | The linear range was 0.25~10 nmol/L (r20.991), and the detection limit of thrombin was 55.6 pmol/L. Regarding the advantages of high efficiency and rapid separation, low sample consumption, and high sensitivity, CE-LIF is a potential and powerful alternative to conventional immunoaffinity assays in clinical diagnostics. chrom-china.com |
