Biotherapeutics such as monoclonal antibody-derived molecules as well as their impurity profiles are becoming more complex. That challenges the routinely applied analysis of high- and low-molecular weight impurities by size exclusion chromatography and UV-absorbance. Possible limitations of SEC-UV can be overcome by adding advanced detection technologies such as multiangle light scattering (MALS) and mass spectrometry (MS). This podcast will explain the different detection methods and the results they deliver. Special emphasis will be placed on the higher requirements for size exclusion columns and methods preceding advanced detection methods.
Determining the Effects of ‘Quantitative Marinating’ on Crayfish Meat with HS-GC-IMS
April 30th 2025A novel method called quantitative marinating (QM) was developed to reduce industrial waste during the processing of crayfish meat, with the taste, flavor, and aroma of crayfish meat processed by various techniques investigated. Headspace-gas chromatography-ion mobility spectrometry (HS-GC-IMS) was used to determine volatile compounds of meat examined.
