A highly sensitive, validated method for atrazine determination in different water types using the QSight 420 LC–MS/MS employed a simple filtration and direct injection.
Using the LX50 UHPLC and QSight 420 triple quad MS, three analytical methods were developed to provide sensitive, reproducible results without the need for pre-concentration steps.
A methodology for a sensitive and repeatable analysis of PPCPs in drinking water utilizing the QSight SP50 Online SPE system coupled to a QSight 220 MS/MS.

IdeS, a cysteine protease, is used for partial digestion of mAbs and generates a (Fab’)2 fragment and two Fc fragments (Fc/2) for better characterization of the Fc fragment.
Selectivity of two high-pH stable Agilent InfinityLab Poroshell 120 C18 columns is compared with pesticides using a pH 10 formate buffer and acetonitrile gradient.
This application combines cysteine proteases IgdE and IdeS, to observe conserved and hypervariable regions of the antibody, as well as identification of other variants.
IgdE allows for better characterization of the antibody and yields an intact Fc and an intact Fab fragment that can be further isolated and characterized.
