chromatograms at individual wavelengths instead of from spectra offers two
advantages: it eliminates the need to perform extractions for chromatograms
that do not require spectral data and it conserves disk space.
Dionex ICS Series Variable Wavelength Detector (VWD)
The VWD is a dual-beam, variable wavelength photometer with one
measurement and one internal reference beam. Spectral capability from 190 to
900 nm is provided by two light sources: a deuterium lamp for ultraviolet
detection and a tungsten lamp for visible wavelength operation. The four-
channel detector measures at up to four wavelengths simultaneously. The
VWD contains a built-in holmium oxide filter for wavelength verification. To
suppress higher-order radiation, two optical filters can be inserted
(automatically) into the light path.
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 FastLock
ionization techniques: atmospheric pressure chemical ionization (APCI) and
electrospray ionization (ESI).
During a scan, ions of selected mass-to-charge ratios are sequentially
transmitted through a quadrupole mass filter analyzer. The MS detector can
perform both full-range scans and selected ion monitoring (SIM) scans.
