The final component common to all mass spectrometer systems is a means of detecting or counting the number of ions of a specific m/z value. These devices are called detectors and they too come in ...

An immense advantage of EM 2 detectors is that—when calibrated properly—they are noiseless and single ion counting is possible. The essence of an EM is a serial connection of discrete metal plates ...

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 ...

Researchers 3D printed a miniature ionizer, a key component of a mass spectrometer. Their device could someday enable an affordable, in-home mass spectrometer for health monitoring. Mass spectrometry, ...
