Impurities Detection of Anhydrous Lactose with UV Vis

Spectrophotometric Method as per US and European Pharmacopeia

This application note provides a method for the detection of impurities in anhydrous lactose samples using METTLER TOLEDO's UV/VIS spectrophotometer.
 

Why Is There a Need for Impurity Detection?

Lactose is a popular excipient in tablets and aerosols in the pharmaceutical industry. To ensure optimal performance in pharmaceutical formulations, it is crucial to utilize lactose samples that are clear in solution and have low protein residue. 

 

How Is Impurity Detected?

The detection of impurities in anhydrous lactose is carried out using standard test method as per the USP and Ph.Eur. This method utilizes UV Vis spectroscopy at a fixed wavelength to detect protein and light-absorbing impurities in lactose samples.
