Product overview
The EXPEC-5231 GC-MS/MS combines gas chromatography and mass spectrometry in one gas chromatography machine, delivering cold-spot-free sample transfer and reliable ionization.
The EXPEC-5231 is a gas chromatography triple quadrupole mass spectrometer, incorporating the latest advances in mass spectrometry technology from BDHME, a trusted GC-MS/MS supplier. It combines gas chromatography separation and tandem mass spectrometry detection as a GC-MS/MS system. It provides the laboratories with a reliable gas chromatography analyzer for identification and quantification of trace-level compounds in complex sample matrices.
The design of the ion source/interface is a major element and has been designed with no cold spots anywhere along the sample path. This ensures constant sample delivery and high ionisation efficiency even during long analytical runs. As a leading GC-MS/MS supplier, we provide support across the UAE, Saudi Arabia, Qatar, Kuwait, Oman, and Bahrain, ensuring laboratories throughout the region have precision and consistency of gas chromatography and mass spectrometry working together.
The EXPEC-5231 is built on the proven principles of gas chromatography mass spectrometry and features a well-designed ion source and a flow path that is free of cold spots from injection to detection. This is important in practice as any point along the interface where sample can condense or degrade will lead to poor peak shape, carryover and inconsistent results. The EXPEC-5231 eliminates these weak points and provides consistent sample transfer and reliable ionization over multiple runs.
The instrument is a gas chromatography machine with tandem mass spectrometry, suitable for laboratories that need both the separating power of GC and the selectivity of MS/MS detection. Typical applications include environmental monitoring, food safety analysis, agricultural chemical residue testing, and evaluation of traditional Chinese medicine samples, where accuracy and reproducibility are most important.
In several fields such as the testing needs can be met by the EXPEC-5231:
- Environmental Monitoring
- Food Safety
- Biomedicine
- Forensic and Toxicology
The system lends itself well to these varied testing environments in that it is a complete gas chromatography and mass spectrometry platform (versus a single purpose tool) and therefore does not require separate instrumentation for each application.
- The EXPEC-5231 is built around an EI ion source and a GC-MS interface that has no cold spots in the sample path. Together with a hexapole collision cell and a tandem quadrupole mass analyzer design, this ensures efficient sample transmission and consistent ionization efficiency.
- This fixed mass analyzer configuration is well suited for a broad range of mass spectrometry research applications and is capable of performing multiple mass analysis scan types as needed for testing.
- The collision cell has been engineered to optimise ion transmission and thereby improve the sensitivity in all scan modes.
- These are full scan, SIM, SRM, neutral loss scan, product ion scan, precursor ion scan, and MRM.
- The principle of the GC-MS/MS instrument is based on two stages of mass analysis separated by the collision cell, which makes the detection more selective and specific than in a single stage GC-MS instrument.
- This is the main difference between tandem MS/MS and conventional single quadrupole systems and is a primary contributor to the performance of the EXPEC-5231 for the supported scan types.
- BDHME’s advanced gas chromatograph-mass spectrometry solutions for environmental, food, agricultural and pharmaceutical testing workflows The EXPEC-5231 is the choice for labs that need to compare GC/MS instruments and gas chromatograph mass spectrometers, providing a stable, cold-spot-free interface and flexible scan capabilities in one system.
