In use at Brooks Rand Labs since 2006 and introduced commercially
in 2007, MERX is the world’s first commercial automated analytical
system based on US EPA Method 1630 for methylmercury analysis.
Around the world, numerous national environmental agencies and
leading universities have quickly embraced MERX as an easy-to-use,
robust, and reliable system that delivers high quality data.
- Ultra-low level – All MERX systems undergo rigorous QC testing to
ensure they achieve an instrument detection limit of <0.002
ng/L. That’s less than 2 parts-per-quadrillion!
- Wide linear range – quantifiable range of 5000x (0.005 ng/L - 25
- Reduced carryover contamination – With the patent pending
gas-pressurized liquid handling system, the purge gas not only
transfers the ethylated sample to the purge vessel, but also
continues to flow through the sample vial and transfer line to
remove any residual volatile mercury compounds, thus allowing the
next sample to be processed immediately without a rinse cycle.
- Sharper peaks – The patent pending ballistic trap heating releases
the ethylated mercury species instantly, resulting in sharper peaks
and improved GC separation.
- Fast – MERX utilizes a multiple trap configuration, such that all
three traps are in use simultaneously at different stages in the
analytical process, resulting in runs every 6.5 minutes or less.
- Less maintenance – With the “pump-free” MERX system, there is no
pump maintenance or constant requirements for tubing replacement.
MERX has only a few replacement parts, which are all easily
accessible and designed for longevity. Trap sets average over 4000
runs and most other replacement parts last much longer.
