The adjustment-free high performance electrospray ionization source
with plug and play probe delivers robustness and reliability.
It is in regard to these aspects that we would like to raise important concerns about the ionization source
used in the study.
In EC-LS DESI-MS, an electrosonic spray ionization source
was used to generate a spray directed to the exit of the liquid sample capillary positioned perpendicularly to the spray and the MS inlet.

For mass spectrometric determination, the UPLC system was hyphenated with an ultrahigh definition accurate mass quadrupole time-of-flight mass spectrometry (MS) system (Agilent Technologies G6540A) by a multimode ionization source
Shimadzu's DUIS ionization source
includes both the ESI and APCI (atmospheric pressure chemical ionization) sources.
Other enhancements include Chemical Ionization Source
and Backflush capabilities as standard on all GC/Q-TOF systems.
The fourth harmonic emission of a Nd:YAG laser (Crylas, 266 nm, 1 ns, 1 kHz) was employed as an ionization source
. One [micro]L of the analyte was injected into a GC system (Agilent Technologies, 6890N) using an autosampler (Agilent Technologies, 7683B) followed by a DB-5 (30 m x 0.32 mm I.D.) capillary column.
* The active exhaust atmospheric pressure ionization source
with a robust orifice vacuum interface significantly enhances quantitative robustness for difficult samples;
The cluster is highlighted by a 2' pair of O-class stars: 7.3-magnitude HD 17505 (the primary ionization source
) and 8.3-magnitude HD 17520.
The Xevo also features the latest generation of Waters' ZSpray ionization source
, which is an integrated design that allows users to switch between various sources without any tools.
