Zusammenfassung
(EN)
A valid state of an analytical system that includes a light source and a detector 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 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 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.

具有验证单元的光谱仪包括:验证单元,使得由光源产生的光在光从光源到探测器传输过程中至少一次通过该验证单元,包含参考气体,参考气体包括已知量目标分析物;流切换装置,在样本分析模式过程中将样本气体引导进入光的路径,并在验证模式过程中引导零气体进入光的路径,零气体在光源产生的波长范围内具有至少一个已知且可忽略的第一光吸收率特性;执行以下操作的控制器:接收量化在验证模式过程中在探测器接收的光的强度的光强度数据,比较光强度数据与表示验证模式中的至少一个先前测量的存储的数据集合;如果第一光强度数据和存储的数据集合不一致超过了预定阈值量,则确定出现验证失败。可以低成本、低复杂度进行气体分析器已有校准的验证。
