Mass spectrometry (MS) plays a vital role in many aspects of our lives, from diagnosing illness and detecting food contaminants to fighting fraud. In order for a sample to be analyzed by MS, it must ...

Explore how to boost confidence in your chemical ionization mass spectrometry results and see why gas reference materials are essential for reliable data in PTR-MS and SIFT-MS.

The QTOF mass spectrometer usually exhibits mass accuracy in the range of 1‐5 ppm. An electron impact (EI) or a chemical ionization (CI) ion source can be used to operate the mass spectrometer .

Extractive electrospray ionization mass spectrometry (EESI-MS) allows the real-time, direct analysis of complex gaseous and liquid samples without any sample pretreatment under ambient conditions.

Proton transfer reaction mass spectrometry (PTR-MS) and selected ion flow tube mass spectrometry (SIFT-MS) are well-established, field-deployable chemical ionization techniques known for their ...
