1901 HgENV Coal Fly Ash NIST 1633c - Technical Note

This technical note describes the analysis of Coal Fly Ash (NIST 1633c) by EPA 7471B on the QuickTrace® M-7600 mercury analyzer. The analysis utilized a reduced internal diameter (ID) tubing for the stannous chloride (SnCl2), sample and waste lines. This configuration reduces reagent and waste and is validated in Application Note: AN1905 – Green Chemistry: Decreased Reagent Consumption and Waste Using Reduced ID Tubing on the QuickTrace® M-7600 CVAA Mercury Analyzer
