摘要:
A valid state of an analytical system that includes a light source (102) and a detector (106) can be verified by determining that deviation of first light intensity data quantifying a first intensity of light received at the detector from the light source after the light has passed at least once through each of a reference gas in a validation cell (114) and a zero gas from a stored data set does not exceed a pre-defined threshold deviation. The stored data set can represent at least one previous measurement collected during a previous instrument validation process performed on the analytical system. The reference gas can include a known amount of an analyte. A concentration of the analyte in a sample gas in a measurement cell (112) can be determined by correcting second light intensity data quantifying a second intensity of the light received at the detector after the light passes at least once through each of the reference gas in the validation cell and a sample gas containing an unknown concentration of the analyte compound. Related systems, methods, and articles of manufacture are also described.
摘要(中):
包括光源(102)和检测器(106)的分析系统的有效状态可以通过确定量化光检测器上接收的第一光强与光源之后的光的第一光强度数据的偏差来验证 已经通过至少一次通过验证单元(114)中的参考气体,并且来自存储的数据集的零气体不超过预定义的阈值偏差。 存储的数据集可以表示在分析系统上执行的先前的仪器验证过程期间收集的至少一个以前的测量。 参考气体可以包括已知量的分析物。 测量单元(112)中的样本气体中的分析物的浓度可以通过校正第二光强度数据来确定,该第二光强数据定量在光通过至少一次通过每个参考气体之后在检测器处接收的光的第二强度 验证单元和含有未知浓度的分析物的样品气体。 还描述了相关系统,方法和制品。
