摘要:
以德国Analytikjena公司Multi N/C 2100S分析仪为例,研究建立了合理可行的总有机碳分析仪校准方法。在总有机碳分析仪检定规程JJG 821-2005的基础上增加零点漂移、直线性、标准曲线线性和检出限4项特性指标,改变了准确性特性的判定方法;根据仪器的使用频率和稳定性,建议校准周期不超过2年。

Establishment of the Method for Calibrating Total Organic Carbon Analyzer
Abstract:
With Multi N/C 2100S analyzer from Analytikjena, established the method for calibrating total organic carbon (TOC) analyzer. In addition to the parameters in TOC analyzer procedures (JJG821-2005), 4 indexes were added in the method, including zero drift, linearity, correlation with standard curve and examination limit. At the same time, the determination of accuracy was changed. According to the use frequency and stability of apparatus, it is suggested that the calibrating cycle should not be over 2 years.
