碳13红外光谱仪示值误差测量不确定度评定

Evaluation of Uncertainty in Measurement of Indication Error of Carbon 13 Infrared Spectrometer

碳13红外光谱仪是一种测量幽门螺杆菌的医用测量仪器,其主要原理是通过测量人服药前后呼出气体中碳同位素丰度比的变化,来表征该人是否感染幽门螺杆菌。本文通过对碳13红外光谱仪示值误差的不确定度进行分析评定,为该仪器的校准结果的可靠性提供参考依据。

Carbon 13 infrared spectrometer is a medical measuring instrument for measuring Helicobacter pylori.Its main principle is to measure whether the person is infected with Helicobacter pylori by measuring the change of carbon isotope abundance ratio in exhaled gas before and after taking medicine.This paper analyzes and evaluates the uncertainty of the indication error of the carbon 13 infrared spectrometer to provide a reference for the reliability of the calibration results of the instrument.
