摘要：

Parameters of sample packing in diffuse reflectance IR Fourier transform spectroscopy (DRIFTS) have been investigated and optimized. One MPa pressure applied for 1 min was found to provide simultaneously at least +/-3% reproducibility and appropriate band intensity. It has been also demonstrated that this precision can be obtained if the sample mass is controlled to +/-2% and the sample is dry. A simple sample packing accessory was designed and constructed for reproducible sample preparation. Quartz concentration of dust samples has been determined and good agreement has been found with the results of the conventional pellet technique.
