GC×GC–TOF MS with thermal modulation used to provide detailed and sensitive characterisation of pyrolysis oil composition to identify possible contaminants.

This application note showcases a Biozen dSEC-7 SEC chemistry/fluorescence detector solution, offering reliable AAV aggregate analysis in under 10 minutes with as little as 0.5 µL of sample. Across four AAV serotypes, resolution between monomer and aggregates remains consistently high, emphasizing Biozen dSEC-7's efficiency and ability to maintain accurate detection at minimal injection volumes. Ideal for routine testing, this solution ensures precise measurement of a CQA with streamlined sample consumption.
