New Agilent GC/MS Series expands automation, flexibility and performance of flagship product line


PALO ALTO, Calif., Aug. 15, 2006, Agilent Technologies Inc. (NYSE: A) today launched a new series of gas chromatograph/mass spectrometers (GC/MS) that builds on the high levels of reliability, productivity and performance of its flagship 5975 instruments. The Agilent 5975B Series MSD offers users new software tools and additional options for integrated autosamplers. A new oil-free vacuum pump enhances productivity by significantly reducing the need for maintenance.

“The new 5975B lets customers tailor the innovative 5975 platform to their workflows in a number of highly useful ways,” said Sihem Ben Mahmoud, Agilent product manager. “Last year we introduced a GC/MS platform, which performs full-scan and selected ion monitoring (SIM) analyses synchronously, with software that automatically creates a SIM method from a scan method. It also permits the exchange of methods electronically across multiple, far-flung labs. Now we’re extending this performance through enhanced software, choice of autosampler and oil-free vacuum pump.”

The Agilent 5975B Series MSD is available now.

New Automation Option

The Agilent 5975B GC/MS is fully compatible not only with the Agilent 7683 ALS, the world’s most widely used autosampler for GC, but also with CTC Analytics’ CombiPAL and GC PAL automated sample injectors. The new edition of the Agilent GC/MS ChemStation software seamlessly integrates the CTC sample injectors for unsurpassed speed, efficiency and flexibility. The same autosampler can perform liquid, headspace and SPME injections. Agilent also offers CTC-recommended consumables such as: headspace and magnetic caps, autosampler syringes, vials and caps and well-plate sample trays and closing mats.

Agilent’s 5975B series MSD is the first GC/MS system to offer the SemiQuant feature, an easy, fast and automated way to estimate the concentration of non-calibrated compounds in samples. This estimation can be based on the response for a similar compound such as a homolog or congener. It can also be performed when a standard is unavailable and the user wants to make a provisional estimate based on another compound. Users can convert an entire method to a SemiQuant method, or SemiQuant compounds can be added to any method.

The platform also offers a new suite of software-productivity tools to simplify method setup, instrument maintenance and data processing:

* AutoSIM Setup automatically converts any full-scan method to a high-sensitivity SIM or SIM/scan method.
* Enhanced Data Analysis is a set of qualitative-analysis tools for chromatogram, spectrum, calibration, quantitation and reports.
* Easy EIC creates a single or multiple EIC in the chromatogram window and simultaneously displays up to three spectrum windows.
* Export-reports capability allows users to export to XLS, HTML or XML formats.

Data Analysis Reduced from Hours to Minutes

Agilent’s Deconvolution Reporting Software (DRS) eliminates most of the delay and tedium from the review of GC/MS data. For example, a skilled analyst recently reduced the time it took to process 17 surface water samples by GC/MS from approximately eight hours to about 30 minutes, while finding an additional 99 compounds. This software combines the Agilent MSD ChemStation software, the National Institute of Standards and Technology (NIST) Mass Spectral Search Program, with the NIST MS library and NISTS’s Automated Mass Spectral Deconvolution and Identification Software. DRS easily and completely automates quantitation, spectral deconvolution and library searching in a single reporting package.

Proven Hardware

The system is based on the Agilent 6890N network GC, the industry’s best-selling model. It can accommodate up to two GC detectors plus the mass selective detector, and acquire data from all three simultaneously. Its modular design allows for field upgrades as laboratory requirements change.

The Agilent 5975B features an inert ion source to perform well with active compounds, and the standard ionization source performs both electron impact ionization and chemical ionization (CI). The design makes CI easy to perform, thanks to a dual gas inlet port, automated CI adjustment and CI autotune.

The system contains a true hyperbolic quadrupole mass analyzer for maximum transmission and resolution. The proprietary quadrupole provides the industry’s most stable mass axis for longer-lasting tune and calibration stability. The thermally stable quadrupole can be heated to 200 degrees Celsius for long-term mass axis stability.

To further enhance the reliability, Agilent is the first GC/MS manufacturer to offer an oil-free vacuum pump which is virtually maintenance free while eliminating any chance of oil leaks or contamination.

“The Agilent 5975B is the latest example of our 30-year tradition of leadership in GC/MS, beginning with the first bench-top instrument in 1976,” Ben Mahmoud added. “Our top priority is always performance and rugged reliability. It’s why we’ve adopted the slogan ’All the Performance, All the Time.’”
