在微量分析中，加入的样品量很少，即使是有经验的操作人员，也往往由于样品量太少，移液器本身的误差等许多因素，造成一定的偏差。对此我们采用适当提高加样量的方法，测定结果准确度明显提高，现介绍如下：１　方法１．１　以酶法测定血糖为例，取本室靶值为７．８ｍｍｏｌ? In trace analysis, the amount of sample added is very small, even experienced operators, often due to the sample size is too small, the pipette itself errors and many other factors, resulting in some deviation. In this regard, we use the appropriate increase in sample volume method, the measurement accuracy was significantly improved, are described below: 1 method 1.1 enzymatic determination of blood glucose, for example, take this room target is 7.8mmol?
