Mass spectrometry is an analytical method used to identify different compounds based on the atomic sample constitution of the molecules and their charge state, which enables “blind” analysis of an ...

Mass spectrometry is a key method for studying proteins, playing an increasingly important role in the study of protein modifications, such as phosphorylation, and even in structural biology. These ...

How does Membrane Inlet Mass Spectrometry Work? Membrane Inlet Mass Spectrometry (MIMS) relies on the principles of mass spectrometry and the selective permeability of membranes that allow the passage ...

The gaseous sample comprising of the VOCs to be examined (for instance, ambient air) is directly sampled into the PTR mass spectrometer without preparing any samples. The PTR ionization source is the ...

Mass spectrometry has emerged as the leading technology for protein characterization. New instrumentation is more versatile and user friendly, expanding the application of mass spec technology to ...

Qualitative analysis serves as the foundation for compound identification. It focuses primarily on determining the elemental composition and structure of analytes within a sample. Identifying the ...

A version of this story appeared in Volume 94, Issue 22 Protein drugs, though, aren’t as simple to characterize as the small-molecule drugs that sit in most people’s medicine cabinets. Making sure ...
