Agilent Technologies has introduced the 7200 Q-TOF (quadrupole time-of-flight) gas chromatography/mass spectrometry (GC/MS) system for biological and chemical GC/MS analyses.
The 7200 Q-TOF combines the performance of the Agilent 7890A GC with the high spectral resolution of a Q-TOF analyser.
It is suited for analysing target compounds and unknowns in challenging applications such as metabolomics, food safety, natural products research, environmental analysis, sports-doping detection and energy research.
New Masshunter deconvolution software facilitates the analysis of a range of compounds in TOF mode.
For particularly challenging samples, users can deploy high-resolution product ion spectra in Q-TOF mode to remove matrix interference and clarify fragmentation patterns.
This guides structural elucidation of unknowns, even at trace levels.
A new removable ion source allows R and D labs to switch quickly between optimised EI and PCI/NCI sources with no loss of vacuum in the Q-TOF manifold, saving a great deal of time.
Each step in the source change is monitored by the MS system to ensure error-free operation.
The quartz monolithic quadrupole analyser and collision cell are identical to the one used in the Agilent 7000B Quadrupole GC/MS/MS.
Its stability allows the analyser to be heated to 200C to eliminate contamination commonly seen with metal quadrupoles operated at lower temperatures.
The proprietary Invar flight tube is sealed in a vacuum-insulated shell to maintain excellent mass accuracy, regardless of ambient temperature changes.
Its length and dual-stage ion mirror deliver high resolution across the mass range.
The 7200's fast electronics enable a sampling rate up to 32Gbit/sec, which provides high resolution, mass accuracy and sensitivity for low-abundance samples.
Dual-gain amplifiers simultaneously process detector signals through low- and high-gain channels, providing a dynamic range of 105.
The analogue-to-digital detector records multiple ion events, enabling very accurate mass assignments over a wide mass range and dynamic range of concentrations.
Internal reference mass compounds can be delivered to the source at either low or high concentrations.
Masshunter Software Agilent Masshunter software is designed to facilitate TOF and Q-TOF analyses from instrument setup to final report.
Data analysis tools help users quickly find, compare and identify compounds.
This includes compound-centric data mining and navigating to streamline and simplify MS data analysis.
Next-generation deconvolution function extracts spectral information from complex separations.
For profiling experiments, Mass Profiler Professional automatically identifies significant differences between sample sets and confirms identification through accurate mass library searches.
