Agilent Technologies Makes Powerful GC, GC/MS Capabilities Accessible to
Wider Range of Labs
NEW ORLEANS, LA (Pittcon 2008), March 3, 2008 – Agilent Technologies Inc.
(NYSE: A) today announced four enhancements to its flagship 7890A gas
chromatograph (GC) and 5975C GC/mass spectrometer (GC/MS), designed to improve
analysis of complex mixtures and make powerful qualitative and quantitative
capabilities accessible to a wider range of laboratories.
Cryogen-Free GC x GC
Agilent introduces GC x GC that doesn’t require cryogen. GC x GC, also known as
“comprehensive GC,” is the separation of complex samples by diverting each peak
from a GC column to a second column. This two-column method can substantially
increase peak capacity and resolving power, which is highly useful with complex
mixtures such as petroleum, fuels, fragrance and environmental samples. Until
now, this required cryogenic cooling for modulation between the columns, adding
considerable cost and complexity to the basic GC. Agilent also developed columns
to further enhance GC x GC performance.
This new GC x GC configuration is the latest iteration of capillary flow
technology, introduced with the Agilent 7890A GC in 2007. It uses a differential
flow modulator to focus and transfer effluent from the first column to the
second with great precision and repeatability. Control of the device is fully
integrated into the 7890A. Capillary flow technology is a proprietary
engineering breakthrough for in-oven connections and flow manipulations that
withstand temperature cycles and pressures of GC analyses without leaking.
Agilent capillary flow technology now offers the widest range of
multidimensional capabilities, from its simple 2-D Dean’s switch device for
heart-cutting to analyze for specific peaks in complex mixtures, to
comprehensive GC x GC for detailed sample characterization and component class
determinations.
“The power of GC x GC can now move beyond the realm of the specialized research
lab into the routine analytical lab, thanks to the simplicity of the capillary
flow device and the associated savings in costs and operational difficulty,”
said Shanya Kane, Agilent vice president and general manager, Gas Chromatography
Systems.

Long-Lasting, Stable Nitrogen/Phosphorous Detection
Today Agilent also announced the acquisition of Blos bead nitrogen/phosphorous
detector (NPD) technology for GC. Designed to increase productivity and uptime
compared to existing NPD designs, the Blos NPD is well-suited for environmental
and forensic applications.
The Blos NPD is built for a very long lifetime and provides high operational
stability throughout its lifetime. The unit resists ambient humidity and
moisture, contributing to this long life and stability.
“We observed the great performance and durability of these detectors in Europe,
and saw excellent potential for making this technology available globally,”
Shanya Kane said. “That’s why we acquired the technology.”
The Blos bead NPD for GC is expected to be available from Agilent later this
year.
High-Efficiency Capillary GC Columns
Agilent also chose Pittcon to introduce Agilent J&W High-Efficiency Capillary GC
columns. They are designed for fast chromatography where high speed and
resolution are needed simultaneously. Applications include high-throughput
screening, fast process monitoring, rapid QC analysis, and quick method
development for a wide variety of sample matrices such as environmental,
petrochemicals, flavors/fragrance and pharmaceutical samples.
This column’s smaller inside diameter of 0.18 mm delivers higher resolution
while its shorter column lengths increase speed. The new Agilent J&W
High-Efficiency Capillary GC columns also require less carrier gas than
comparable columns to reduce cost per experiment. They’re compatible with a wide
range of existing GC instruments and operate with helium or hydrogen. Users can
chose from more than 20 stationary phases and can easily and reliably translate
current methods with the help of Agilent’s free Method Translation Software.

Triple-Axis Detector Raises GC/MS Signal-to-Noise Ratio
Agilent’s new Triple-Axis Detector (TAD) for the Agilent 5975C GC/MS delivers
the industry’s strongest signal at any given operating gain, thanks to unique
geometry and a new electron multiplier design. The signal is enhanced while
neutral noise is substantially reduced. The new detector is also designed to
last twice as long as previous models when operated properly.
“By taking a fresh look at the design, we were able to produce a detector that
provides the superior performance demanded by scientists working in forensics,
metabolomics and other high-precision fields, while lowering the cost of
ownership through an extended lifetime,” said Monty Benefiel, Agilent GC/MS
marketing manager.
The new TAD lowers the detection limits of the Agilent 5975C GC/MS by a factor
of two, to an industry-leading signal-to-noise ratio of 400:1 for 1 pg OFN. The
new design places the electron multiplier off-axis from the transmission
quadrupole, maximizing ion collection (increasing signal) while reducing neutral
noise. The detector also introduces a triple channel multiplier with more
amplification and longer life than previous units. Agilent’s new Gain Normalized
optimization of the electron multiplier delivers optimal balance between ion
count, linearity and life expectancy. Gain Normalization also provides
consistent sensitivity as the electron multiplier ages, and provides consistent
ion counts between multiple GC/MS systems.
New Deconvolution Software: More Accurate GC/MS Library Matches and
Quantification
Agilent today announced the introduction of Deconvolution Reporting Software
(DRS) version A.04.00, used to extract MS signals of interest from complex
mixtures, including closely co-eluting peaks. Deconvolution works especially
well with dirty matrices.
Agilent DRS is an application for target compound analysis that combines results
from Agilent ChemStation for GC/MS, the National Institute of Standards and
Technology (NIST) Automated Mass Spectral Deconvolution and Identification
Software (AMDIS) and the NIST 2005 Mass Spectral Search Program into one
easy-to-read report.
The new version of Agilent DRS provides quantitation of AMDIS deconvoluted
results in Agilent MSD ChemStation QEdit. It also generates summary reports of
both MSD and AMDIS deconvoluted results for efficient review.
Users save considerable amounts of time and cost with Agilent DRS. Complex data
can be analyzed in as little as one minute of processing time per sample.
Agilent DRS is more thorough than standard quantification and library search
methods, and finds additional targets not found by the conventional data system.
Screening and quantitation can be performed in a single run, and there’s no need
to learn a separate software application. For more information please visit
www.chem.agilent.com/scripts/generic.asp?lpage=14509&indcol=N&prodcol=Y .
Through July of this year, Agilent is offering 50 percent off the price of a
software bundle including Agilent DRS, NIST05 and one Retention Time Lock
library.
