为了提高检验质量,保证检测结果的准确性、可靠性、可行性和公正性,特别是基层检验室,在检测过程中必须严格执行质量控制措施,经过几年的摸索,总结以下经验。 1、每一个分析工作者都应该有严肃认真的工作态度,精密细致的观察操作和整齐、清洁的实验习惯。 2、测定过程中必须进行空白值试验,空白试验与样品测定同时进行,空白试验至少做两个平行样。两个空白试验值的平均值按规定方法计算检测限,该值如高于标准分析方法中规定值,则应找出原因予以纠正,直到空白试验符合要求后才能正式测定试样;或者可以测定两个空白试验平行样的相对偏差,它不得大于50％,否则也应找出原因予以纠正。
In order to improve the quality of inspection and ensure the accuracy, reliability, feasibility and fairness of the test results, especially in the grass-roots inspection laboratories, quality control measures must be strictly implemented in the testing process. After several years of exploration, the following experiences have been summarized. 1, Each analyst should have a serious and serious working attitude, careful observation and operation of neat and clean experimental habits. 2, the measurement process must be blank value test, blank test and sample determination at the same time, blank test at least two parallel samples. The average value of the two blank test values calculated according to the provisions of the detection limit, if the value is higher than the standard analytical methods, the value should be found to be corrected until the blank test to meet the requirements before the formal test sample; or can be measured Two blank test parallel sample relative deviation, it can not be greater than 50%, or should also find out the reason to be corrected.
