Extremely Low Level Mercury Vapor Analysis

Some applications require the analysis of mercury at very low levels, for example, 100 nanograms/cubic meter (ng/mg3) or .0001 milligrams/cubic meter (mg/m3) level. For this testing, a variation on the standard flow rate of 5 cc/minute may be more practical in order to shorten the sample collection time.

NOTE: Arizona Instrument recommends a flow rate of 5 cc/minute for most industrial hygiene applications. Specifications are written based on suchy a flow rate. The following a suggested alternative and should be verified by using your own internal quality control standards. Direct injections of mercury vapor using the Jerome® Mercury Functional Test Kit should be used in the Q.C. program.
