App Notes

This Application Note describes the GC–MS analysis of humidified canister ‘air toxics’ samples at various relative humidities, using cryogen-free systems for thermal desorption preconcentration.

Here, we compare GC-TOFMS and GC×GC-TOFMS data for a representative commercial perfume sample to demonstrate the type of information that can be gained with a comprehensive two-dimensional separation.

In this technical note, we present an overview of the directDIA workflow and its application to a set of six human liver samples derived from healthy and adjacent cancerous tissue.

Mass spectrometry can be now deployed for onsite pesticide screening in real time.

In this report, the complete automation of an on-line SPE-LC/MS/MS method used for the determination of perfluorinated compounds in water samples is discussed.

This white paper lists the key items that you should think about when buying a new system and discusses the reasons for their importance.

To help reduce the incidence of false positive and false negative reporting in pesticide residue monitoring routine, multiple-reaction monitoring (MRM) methods have been enhanced to monitor a higher number of fragment ion transitions

We describe herein the implementation and merits of a novel standard mixture (referred to as ProteusQC™) for bottom-up proteomic applications.

For analysis of very polar compounds the option to work with 100% aqueous mobile phases is required.

This white paper lists the top ten reasons you need an advanced multi-detector GPC system.
