The benefits of an analytical quality by design (AQbD) approach to method development cannot be underestimated. The Column spoke to Changqin Hu and Xia Zhang from the National Institutes for Food Drug Control, in Beijing, China, about their work developing a dual-gradient elution stability-indicating method for cloxacillin within an AQbD framework.

This study describes the analysis of fragranced washing detergent and washing powder using probe-based headspace and immersive sorptive extraction, in conjunction with analysis by thermal desorption–gas chromatography–mass spectrometry (TD–GC–MS). As well as discussing the differences between the two samples, the analyte ranges covered by headspace and immersive sampling are compared.
