Mercury vapor detection by Arizona Instrument
March 1, 2016
Increase mercury vapor detection range by 10X. New vapor dilution module extends detection range of the Jerome J505 from nanograms to milligrams. How it works: The new 10:1 dilution module for the J505 reduces the concentration of mercury vapor in the sample stream by a factor of ten, allowing for a much higher detection limit.
