离子色谱法测定水中无机阴离子测量参数的优化分析
Optimization of the Measurement Parameters for Determination of Inorganic Anions of Water by Ion Chromatography

离子色谱仪的品牌型号多样，具有各自的特点，用户会选择不同品牌、型号及配置的仪器，根据《水质 无机阴离子的测定 离子色谱法》(HJ84-2016)的方法，调整戴安(ICS-2100)离子色谱仪测定水体中F^？、Cl^？、NO₂^-、NO₃^-、SO₄^2-等项目的淋洗液浓度、流速、抑制器电流三个参数，优化色谱峰峰型、峰宽、分析时间等，建立一套色谱条件快速高效的优化方法，对标准方法进行确认，满足监测需求，提高了检测项目分离度、灵敏度、准确度和监测效率。
Users will choose different brands, models and configuration of the instrument of ion chromato-graph which have various brand models with their own characteristics. According to the Water Quality Determination of the Inorganic Anion Ion Chromatography (HJ84-2016), the eluent concen-tration, flow rate and suppressor current were adjusted to determine the F^？, Cl^？, NO₂^-, NO₃^-, SO₄^2- of water by ion chromatography of Dionex (ICS-2100). Through optimizing the chromatographic peak type, peak width and analysis time of the methods, a fast and efficient optimization method for chromatographic conditions was established, and the standard methods were confirmed to meet the monitoring requirements. Our study could improve the separation, sensitivity, accuracy and monitoring efficiency of detection items.
