工业气相色谱仪的标定是仪器应用中的重要问题,一般都采用标准气做外标法标定。但是,对用户来说,多种规格的标准气价格贵且难买到。用其他辅助方法标定工业色谱,由于标定方法受局限性过大,且不能连续进行,操作较为麻烦,误差大而准确性差,因此,工业色谱的标定工作成为其推广应用中的难题。 The calibration of industrial gas chromatograph is an important issue in the application of instruments. Generally, standard gas is used for calibration by external standard method. However, a variety of standard gas is expensive and difficult to buy for users. Calibration of industrial chromatography with other auxiliary methods, calibration methods are too limited because of limitations, and can not be carried out continuously, the operation is more cumbersome, the error is large and the accuracy is poor, therefore, the calibration of industrial chromatography has become its application of the problem.
