E²M
Enhanced Environmental Mass Spectrometer
The E2M is a mobile, compact and rugged GC/MS system for fast, reliable onsite identification and quantification of organic substances in soil, air, water and from surfaces.
The E2M is able to identify any organic chemical from any medium (soil, water, air) within 20 minutes via complementary sampling techniques. Specifications and performance are not limited to a selected portion of chemicals. New libraries can be created and used by the customer. The detection limit for volatile organic compounds is from low ppb to the low ppm range depending on the analytical procedure, e.g. adsorbent enrichment (low ppb range) or on-line monitoring (approx. 1 ppm range) from ambient air. Training and operation is reduced to the lowest possible level whilst the reliability is increased.
System components and accessories
- E2M Basic unit
- Gas chromatograph (with Thermodesorber/Injector programmable up to 240 °C)
- Air/Surface probe (Direct measurement of air and surface contaminations)
- Personal Computer for the detector control and for the data evaluation
- Injector kit (Split-injection of liquid samples)
- Sampling case (Fast on-site sample preparation)
Typical Applications
- mobile on-site analysis
- environmental protection
- first responders for chemical hazards, fire brigades and other blue-light services
- homeland defense
- event monitoring
Control Software
The E2M software includes all standard MS acquisition methods.
- Full spectra acquisition: 0…520 da
- Single ion monitoring (SIM)
- Easy to use graphical user interface
- Adaptation to existing fire brigades SOP
- Dangerous goods data base (DGDB) linkage
The E2M is supported by new Software Modules for instrument control and data acquisition. The E2M Control (Advanced User) is used to set all parameters of the instrument and therefore to create new applications.
The E2M Analysis (Operator level) supports an easy and uncomplicated operation of the system for already prepared methods.
Both software tools include the fully automated data evaluation based on the NIST spectra library (National Institute of Standards and Technology), and the Bruker TICLib (Toxic Industrial Compounds) or a customer specific library.
