Jerome J505 Mercury Vapor Analyzer - Operation Manual

The Jerome® J505 Mercury Vapor Analyzer is an ambient air analyzer with a range of 0.05 to 500 micrograms of mercury vapor per cubic meter (μg/m3 Hg). The instrument uses atomic fluorescence spectroscopy for mercury analysis, which allows the detection cell to be simpler, smaller, more durable and lighter weight than competing spectroscopy instruments. A smaller optical cell also requires less flow to purge the system, allowing the J505 to run at a lower flow rate than competing spectroscopy instruments. A low flow rate is essential for accurate low-level mercury detection because higher flow reduces the ability to pinpoint the source and dilutes the sample stream, negatively affecting instrument accuracy.
