  • The determination of mercury at ultratrace levels using FIMS and amalgamation technique

    The PerkinElmer Flow Injection Mercury System (FIMS) is used in combination with an amalgama¬tion preconcentration technique to determine Hg at ultratrace concentrations. Using a 10-mL sample volume, the instrumental detection limit is 0.3 ng/L. The method detection limit obtained in drinking water is 1.0 ng/L with a spike recovery of 100 ± 4%. The operating conditions for the ...

  • Determination of mercury with on-line addition of stannous chloride uUsing an axial ICP-OES

    Mercury is one of the most toxic heavy metals in the environment. It is therefore important to routinely monitor the Hg level in many types of samples. The US EPA approved methodology for the determination of Hg uses the cold vapor technique with stannous chloride as the reducing agent1. This methodology is applicable to Hg determinations in a range of waters (drinking, ground, surface, sea and ...

  • Determination of Ultra-Trace Mercury Vapor Levels from Industrial & Military Metal Components

    For many years, scrap metal reclaimers did not separate the materials containing mercury from other metals. Such things as mercury switches, dental amalgam, thermometers, and refining wastes from copper, gold and silver were processed along with the typical industrial metals. The result is that a significant portion of the Ferrous and non-Ferrous metals and alloys used today contain some metallic ...
