Quick determination of water in Tianma capsule of different pharmaceutical factories by near infrared reflectance spectroscopy

Objective To establish a method for quick determination of water content in Tianma capsule of different pharmaceutical factories by near infrared reflectance（NIR） spectroscopy.Methods Tianma capsule was used as test samples,and the content of water was analyzed by NIR spectra.The OPUS software was used to establish the calibration model for water content.Data of the confirmation sample was similar.Results It was a quick and accurate analysis method for determination of the water contents in Tianma capsule.The relative errors was 0.03%~2.70%.Conclusion The established method is a rapid and simple way with good accuracy and reproducibility for the determination of water content,and it is also a non-destructive assay.The method can be used in drug administration and supervision for quick determination of water content in Tianma capsule.
