Invented a half-century ago by Nobel laureate Wolfgang Paul, the quadrupole mass filter has become an integral part of some of the most sophisticated mass spectrometers. Consisting of four parallel ...

Hats off to [Paul Brooking] as he shows off his homemade mass spectrometer in two recent videos you can see below. The first video demonstrates that the device works. The second video shows details ...

Yost had similar ambitions, though he thought of it as “instrumentalizing” a computer. He joined Enke’s group especially to work on the computerization project. He remembered so-called quadrupole mass ...

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 ...

Development of two new techniques for studying the gas phase chemistry of negative ions is reported. Collision induced dissociation (CID) of ( M-1)- ions has been accomplished in a newly constructed ...

The five-day Comprehensive GC-MS introduces the fundamental theory of single quadrupole GC-MS along with the operation, maintenance and troubleshooting of the Agilent single quadrupole Mass ...

This photo shows an example of a 3D printed miniaturized quadrupole mass filter. They can be fabricated in a matter of hours for a few dollars. Mass spectrometers, devices that identify chemical ...
