Four different calibration methods were used for quantitative analysis of quartz and calcite in atmospheric aerosols by diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS): (A) conventional calibration with one measurement on each standard (single calibration); (B) calibration with an internal standard; (C) calibration with parallel (n = 4) measurements on each standard (multiple calibration); (D) multiple calibration followed by reference reflectance correction. The accuracy and the precision of the methods were compared and it was found that by using method D the reliability of the conventional pellet preparation transmission technique can be achieved.
采用四种不同的校准方法，通过漫反射红外傅里叶变换光谱法（DRIFTS）对大气气溶胶中的石英和方解石进行定量分析：（A）对每个标准品进行一次测量的常规校准（单次校准）；（B）采用内标进行校准；（C）对每个标准品进行平行（n = 4）测量的校准（多次校准）；（D）多次校准后进行参考反射率校正。对这些方法的准确度和精密度进行了比较，发现使用方法D可以实现传统压片制备透射技术的可靠性。
