including electron ionization (EI), electrospray ionization (ESI), atmospheric pressure chemical ionization (APCI), and atmospheric pressure photo ionization (APPI). Tandem mass spectrometry (MS/MS or ...

Scientists have developed a new technique to screen engineered enzyme reactions, which could lead to faster and more ...

It describes options and how to calibrate plane parallel ionization chambers, against air kerma or absorbed dose to water standards at cobalt-60 gamma ray energies. The use of these chambers to ...

This instrument couples a gas chromatographic separation of analytes prior to mass analysis using electron impact (EI ... and hydrogen/deuterium exchange-mass spectrometry (HDX-MS). It has an ...
