Researchers 3D printed a mini quadrupole mass filter, a key component of a mass spectrometer, that performs as well as some commercial-grade devices. It can be fabricated in hours for a few dollars ...

A new mass spectrometry technique captures molecules of lower abundance in a sample, providing a more comprehensive sample ...

MALDI remains a powerful tool for analyzing large biomolecules with minimal fragmentation. In this process, peptides or proteins are co-crystallized with a matrix on a metal plate. A laser pulse ...

To identify specific chemicals or molecules in the life sciences and medical research, scientists often use mass spectrometry (MS), usually paired with liquid chromatography (LC). These technologies ...

Effective protein characterization depends on the precise isolation and fragmentation of peptide ions within the mass spectrometer, typically coupled with liquid chromatography (LC-MS/MS). In a ...
