| 摘 要： | 硫化学发光检测器(SCD)因其线性范围宽、高灵敏度等特性,在国内已经大量应用,但目前对硫化学发光检测器型气相色谱仪(GC-SCD)的检定/校准尚属空白。依据JJG 700-2016《气相色谱仪》,结合GC-SCD使用的实际情况,提出了评价GC-SCD计量性能的5项重要校准项目:柱箱温度稳定性、基线噪声、基线漂移、检测限以及定量重复性,并通过评价实例,验证了5项校准项目的可行性和适用性,以期为GC-SCD检定规程或校准规范的制定提供参考。

| Abstract: | Sulfur chemiluminescence detector (SCD) has been widely used because of its wide linear range, high sensitivity and so on, but the calibration of gas chromatograph with sulfur chemiluminescence detector (GC-SCD) was still a blank. According to JJG 700-2016 Gas Chromatograph, combined with the actual usage of GC-SCD, five important calibration items for evaluating the measurement performance of GC-SCD were put forward, such as temperature stability of the column oven, baseline noise, baseline drift, limit of detection and quantitative repeatability. The feasibility and applicability of the 5 calibration items were verified through evaluation examples, in order to provide references for the establishment of GC-SCD verification regulation or calibration specification. |
