MSQ Plus Mass Spectrometer
The MSQ Plus is an advanced analytical instrument that includes an MS
detector, vacuum pumps, and data system. When integrated with an IC
system, the MSQ Plus provides the separation capability of an IC and the
detection capability of a single-quadrupole MS detector. This provides a
strong starting point for sample analysis by offering a quick and clear
mass identification for chromatographic peaks.
The MS detector contains an atmospheric pressure ionization (API)
source, advanced high efficiency transmission ion optics of a square
quadrupole RF lens and dual RF generators, a mass analyzer, and an ion
detection system. An optional cone wash pump is available for improved
performance when dealing with dirty matrices.
The MS detector is equipped with FastLockā¢ probes for two
complementary ionization techniques: atmospheric pressure chemical
ionization (APCI) and electrospray ionization (ESI). Both ionization
techniques can be run in either the positive or negative ion polarity mode.
The design of the interchangeable probes enables rapid switching of
ionization modes.
During a scan, ions of selected mass-to-charge ratios are sequentially
transmitted through a quadrupole mass filter analyzer. The MS detector
has fully automatic mass scale calibration (15 to 2000 m/z) and tuning
that makes optimization simple and direct. The MS detector can perform
both full-range scans and selected ion monitoring (SIM) scans. When
operating in conjunction with Chromeleon, the MSQ Plus can be set up to
vary the scan type, the ionization technique, and the ion polarity mode.
