SubscribeA series of rugged mass spectrometers for the fast on-site detection of hazardous compounds and CWAs and Toxic Industrial Chemicals (TICs) from air, soil and liquids.
While the EM 640S is an MS system with laboratory analytical specifications that can be transported to and operated at the point of need, the EM 640 can even be operated while underway.
EM 640S - Transportable GC/MS system with laboratory analytical specifications
The EM 640S is a mobile GC/MS system designed for the fast and accurate, high sensitivity analysis of organic compounds in the environment. This system was, besides other applications, chosen for monitoring duties under the terms of the Chemical Weapons Convention, due to the following features:
- After long travel times ready for use within 30 minutes of arrival on-site
- High sensitivity: 1 ng Methyl Stearate in full scan mode gives a signal at m/z 298 with S/N 10:1
- Modular periphery system, easy exchange of GC ovens "primary modules" and sample introduction systems "secondary modules", allow quick adaptations to new analytical problems
- Blinded software for on-site analysis guarantees commercial security
Main EM 640S features
- Direct GC/MS coupling
- Ruggedized one-piece quadrupole
- Two filaments
- Large dynamic range
- Mass range 1-640 m/z
- Built-in membrane (roughing) pump and turbomolecular pump 70 l/s
- 24 V DC, max. 650 W
Main EM 640S applications
- Chemical disarmament monitoring as part of the verification program specified in the Chemical Weapons Convention
- Environment trace analysis (air, water, soil and sediments)
EM 640 - Immediately usable mobile mass spectrometer
The EM 640 is a mobile, very rugged, GC/MS system designed for the fast and simple on-site assessment of chemical catastrophes and accidents as well as other environmental problems involving organic chemicals. Amongst other applications the EM 640 was chosen by various bodies for catastrophe assessment due to the following features:
- Continuous monitoring while underway
- Ready for use on-site as soon as the first sample has been collected
- Has been mounted in vehicles, containers, ships and helicopters
- Specially designed stretcher allows use without external power supply and transfer of running instrument from one transport type to the other e.g. from vehicle to helicopter.
- Quick modification for new analytical problem due to flexible modular periphery system with easy exchange of GC ovens, "primary modules", and sample introduction systems "secondary modules".
- Simplified graphical user software interface (fire fighter graphical interface) which can be used by non-technical personnel.
