The Waters ACQUITY QDa Detector is a mass detector designed to bring high-quality, mass spectral data to chromatographic separations.

LCMS-8050 Mass Spectrometer Increases Quality Analysis

The authors evaluated a variety of materials of construction (MOCs) and found that visible residue limits (VRLs) were higher on some MOCs than on stainless steel. The optimal viewing conditions were dependent on the MOC and the viewing background. The risk of a cleaning failure due to visual failure for different MOCs can be mitigated or eliminated using complementary cleaning validation studies.

Software Improves Monitoring of Pharmaceutical Ingredients

The authors discuss a strategy for developing a risk-based approach for testing of elemental impurities in leachable studies.

The characteristics of tableted solid dosage drugs often depend on the granulation process, so selecting the most appropriate granulation technique and monitoring the process are crucial
