aters® Acquity QDa™ detector is
the first mass detector to bring
high quality, mass spectral data to chromatographic separations. The QDa detector is compatible with Waters’ Acquity
UltraPerformance LC®, Convergence
Chromatography™, Alliance® high
performance liquid chromatography
and supercritical f luid chromatography and LC-based purification systems.
This detector is the realisation of a
vision that started 20 years ago at Waters,
blending chromatography and mass

A
gilent’s 7000C Triple Quadrupole Gas Chromatography Mass
Spectrometer (GC/MS) replaces the
7000B, with capabilities to enhance
system performance, simplify method
optimisation and lower operating costs.
The 7000C integrates the same ionsource technology introduced in the
company’s 5977 series GC/MSD. This
system also has an instrument detection
limit of only 4fg octafluoronapththalene.
There are new integrated intelligence
features shared by the 7890B GC and
7000C, and new tools for the MassHunter software that support rapid
method development. Customers now
possess improved capabilities that offer
long-term supportability and performance. The 7000C together with Agilent
sample-preparation supplies enables sensitive, selective and robust techniques for
measuring trace components in complex
matrices. Their extensive MRM database
of pesticides and environmental pollutants also provide the information needed
for quick and easy method development.
The 7000C offers reliability, efficiency and ultra-low limits of detection
for confidence in trace-level analysis. ⚛

spectrometry technologies together in a
way that gives every analytical scientist
access to mass spectral data. This detector
adds a whole new dimension to separation
science and it is a progressive leap forward
in chromatography detection.
It is a small, easy-to-use and affordable
mass detector that brings high-quality
mass spectral information to chromatographic separations. This greatly enhances
chemical compound identification, which
is important to laboratories doing method
development, sample profiling, chemical
synthesis and purification.
The QDa detector complements
optical detection, such as the PDA detector, by confirming the identity of compounds with mass spectral information. It
extends the limits of sample detection for
a chromatographic separation by quantifying compounds having no UV response
or that are present at levels not detectable
and quantifiable by optical detection.
By simplifying laboratory workflows,
the detector enhances the value of every
analysis and increases productivity by
eliminating the need to run additional
assays or turn to time-consuming alternative techniques in order to establish with
certainty the levels and identity of specific
sample compounds. ⚛
