摘要
提出了在四级站的考核项目中,在考核低浓度硝基苯标准样品时通过改进:曲线绘制方法、取过滤液方法、调pH值方法、标样稀释方法等手段提高考核结果的准确性。
Among all the checked items, the veracity of low concentration nitrobenzene standard samples gets improved through correcting the way of designing the curve, and adjusting the value of pH, and diluting standard sampies and using filter liquid.
