Agilent Technologies has introduced the 7000B triple quadrupole gas chromatograph/mass spectrometer (GC/MS/MS).
The Agilent 7000B provides femtogram-level sensitivity for analyses such as pesticides, PAHs, PCBs, pyrethroids, THC, and steroids in food, environmental, pharmaceutical and forensic matrices.
Agilent's gold-plated quartz, hyperbolic quadrupole analysers operate at temperatures up to 200C without any loss of resolution or sensitivity.
The 7000B extends the performance and capabilities of the 7000A with the introduction of more sensitive electron ionization (EI) source and a new chemical ionization (CI) source.
All of these improvements are reverse compatible to the 7000A.
The high-sensitivity EI source sends more precursor ions to the mass analyser, increasing sensitivity and precision.
Source temperature is programmable up to 350C to accommodate complex matrices.
High temperature also means less cleaning, reducing labour requirements and increasing uptime.
The source is fabricated of solid inert materials, rather than coated, for durability and stable performance.
The new positive and negative CI source generates ideal precursor ions for MS/MS.
Based on the proven CI source of the single quadrupole Agilent 5975C GC/MSD, this PCI/NCI source is built to deliver high sensitivity and trouble-free CI operation.
The 7000B MS/MS achieves an ultra-fast multiple reaction monitoring (MRM) speed of 500 per second without any 'cross talk' between consecutive transitions.
High-speed MRM enables users to determine more compounds per ion group.
Agilent has enhanced the capabilities of the 7890 GC with a multi-mode inlet (splitless, PTV and split) and new high-efficiency backflush tools.
As compared to traditional column bake-out, backflushing high-boiling matrix extends column life, shortens analysis time and reduces source maintenance.
For high-throughput analyses, the Agilent 7000B can be ordered with the Agilent 7693A automatic liquid sampler (ALS).
The ALS is completely modular, letting users configure the exact autosampler required, starting with a basic injector with a 16-sample turret, and adding capabilities as needs expand.
Options include a second injection tower, a 150-vial sample tray and a vial heater/mixer/barcode reader for long, unattended operation including new sample preparation tasks.
The ALS supports sandwich injection, which enables internal standard and/or solvent aliquots to be added to the syringe prior to injection.
The Agilent 7000B GC/MS/MS runs on Masshunter Workstation software for instrument control, data acquisition, qualitative and quantitative data analysis and reporting.
