ANALYTICAL METHODOLOGY--DEVELOPMENT AND INTERPRETATIVE APPLICATION

我们比较了标本混浊度和甘油的影响 甘油三酯测定的九种酶促方法的浓度。 我们检测了51个甘油三酯浓度在0.85-8.21之间的样本 摩尔/L和420 nm浊度相当于&gt；=0.1mmo1/L 甘油三酯。样品浊度和甘油的影响 浓度因方法而异，范围为6.2%至-15.67% 测量结果。浑浊效应的大小是相似的。 甘油的价格。双色法测定甘油三酯 测量受混浊干扰较小。 我们比较了五种离子选择电极和一种量热法。 火焰原子吸收-原子吸收光谱法测定锂 发射光谱。所有分析仪的不精密度为&lt；5% 埃克塔赫姆和贝克曼。分析回收率在5%以内。 除了埃克塔赫姆和巴克斯特之外的所有分析仪的价值。一些药物 除AVL和康宁外，所有分析仪都有干扰。这个 使用巴克斯特、贝克曼和康宁分析仪的结果最接近 那些通过火焰原子发射的。

We compared the effects of specimen turbidity and glycerol concentration on nine enzymatic methods for triglyceride measurement. We assayed 51 specimens with triglyceride concentrations of 0.85-8.21 mmol/L and turbidity at 420 nm equivalent to >=0.1 mmol/L triglyceride. The effects of specimen turbidity and glycerol concentration were method-dependent and ranged from 6.2% to -15.67% of the measured result. The magnitude of the turbidity effect was similar to that for glycerol. A triglyceride assay with a bichromatic measurement was less subject to interference from turbidity. We compared five ion-selective electrodes and a calorimetric method for determination of lithium with flame atomic absorption and atomic emission spectroscopy. Imprecision was <5% for all analyzers except Ektachem and Beckman. Analytical recovery was within 5% of the target value for all analyzers except Ektachem and Baxter. Some drug interference was seen with all analyzers except AVL and Corning. The results with the Baxter, Beckman and Corning analyzers were closest to those by flame atomic emission.
