我们在开展分析检测过程中,常遇到一些用户不会采集样品,致使样品报废,给工作造成严重损失。当今,现代科学技术日新月异,各种先进分析技术广为应用,可以取得高精密、高准确的数据。化验时所称取的分析试样少,只有几克、几百毫克或更少,而检测分析结果必须能代表全部物料的平均组成。因此,仔细而正确地采集具有代表性的“平均试样”,就具有极其重要 We carry out the analysis and testing process, often encountered some users will not collect samples, resulting in sample scrapped, resulting in serious loss of work. Nowadays, with the rapid development of modern science and technology, various kinds of advanced analytical techniques are widely used, and high-precision and highly accurate data can be obtained. The test sample weighed less than a few grams, hundreds of milligrams or less, and test results must be able to represent the average composition of all materials. Therefore, it is extremely important that a representative “average sample” be carefully and correctly collected
