1. General Description page 9 1.2 Measuring principle The UT-3000 uses the Mercury Instruments GoldTrap to capture total gaseous mercury (TGM) directly from the sample. GoldTraps work because mercury sticks to gold at room temperature. The sample gas is pulled through a 0.45 micron PTFE filter and then passes the trap. The gas continues to flow through the trap but the mercury stays behind--trapped on the gold.
