Applying simple PAT tools to crystallisation in process chemistry

23 October 2017 | By

Crystallisation is a common step in the synthesis of organic compounds used to isolate and purify the desired product. As the importance of crystallisation has increased and chemists improve the processes involved, process analytical technology (PAT) tools can be used to design, analyse, and control them. This article considers the…

Determination of glucosamine in food supplements by HILIC-ESI-MS

20 October 2017 | By , , ,

Glucosamine is sold as a food supplement worldwide, but its production is poorly regulated. A direct and reliable method for the quality control of glucosamine in commercial products is of great importance. This article describes a simple, fast and validated ultra-performance liquid chromatography-quadrupole time of flight (UPLC-QToF) for the determination…
