The in-depth analysis and determination of petroleum fractions remain challenging. Evolved gas analysis (EGA) is a complementary method to conventional spray-based and ionization techniques such as ...

ass spectrometry (MS) has evolved into one of the most sensitive analytical methods for the structural characterization of molecules. 1,2 Ionization is critical for volatilizing sample analytes into a ...

Mass spectrometry has become an indispensable analytical tool in all types of drug discovery applications. Development of two ionization techniques, electrospray (ESI) and matrix assisted laser ...

Atmospheric pressure chemical ionization Atmospheric pressure chemical ionization (APCI) is an ionization technique carried out using sources similar to that of electrospray ionization. In this method ...

The dual probe configuration greatly improves on the multimode approaches currently in use for ESI/APCI and ESI/APPI dual sources where at high flow rates the ESI sprayer does not fully desolvate ...

The Western Illinois Mass Spec Center is equipped with an Agilent 6545 Q-TOF LC/MS system with the following modules: a 6545 quadrupole time-of-flight (Q-TOF) mass spectrometer, a 1260 Infinity II ...

The SELECT Series instrument utilizes both traditional chromatography separation and ion mobility spectrometry (IMS) during which chemicals are pushed through a dilute gas to separate structurally ...
