血样加抗凝剂并用水稀释后,直接进样20μl,氘灯扣除背景,用标准加入法定量,标准曲线在0～300ng/ml范围内呈线性;精密度4.8～9.l%(CV);回收率96.2～100.6%;检测限1.42ng(取1ml静脉血)。
Blood samples plus anticoagulants and diluted with water, the direct injection of 20μl, deuterium lamp background subtraction, using standard addition quantitative, standard curve in the range of 0 ~ 300ng / ml linear; precision 4.8 ~ 9.l% (CV) ; Recovery 96.2 ~ 100.6%; detection limit 1.42ng (take 1ml venous blood).
