Our Front End, coupled with your MS, makes the most advanced vapor analyzer in the market
Add a new capability to your MS within the vapor analysis field. Our front end basically includes a high volume sampler for off-line collection of vapors and an ionic mobility unit to add a new dimension to your spectrometry in vapor sensing. Just give us your MS and we will deliver you a complete system for vapor analysis, with reference values of sensitivity and selectivity at your fingertips.
Features and advantages
- Triple filter measurement technology (volatility by desorption-mobility-mass)
- Able to operate off-line (for atmospheric studies, for instance) or on-line.
- No specific chemical preparation of samples is required
- Lowest values of detection of the market. (As low as 0.01 parts per quadrillion for RDX explosive).
- And still at a relatively low cost compared to your MS!!
- Just contact us and check the interfaces available
