Determination of Mercury (Hg) in Water by Hand-Held, Portable Cold Vapor Atomic Fluorescence Spectrometry

Arizona Instrument LLC
14 May 2014

This paper describes the use of a hand-held, portable atomic fluorescence based analyzer to measure mercury concentrations in water, using a method adapted from EPA method 1631, Revision E. This experiment eliminated the requirement of a gold trap, giving it a more robust application, both by portability to work stations and by optimized testing procedures.

Jerome® J505 Mercury Vapor Analyzer

Arizona Instrument LLC

Jerome® J505 - Atomic Fluorescence Spectroscopy Mercury Vapor Analyzer The Jerome® J505 Mercury Vapor Analyzer is a portable fluorescence spectroscopy analyzer, which allows the detection cell to be simpler, smaller, lighter weight and more durable than competing spectroscopy instruments. The highly efficient optical cell requires less flow to purge the system, allowing the J505 to run at a lower flow rate minimizing sample dilution as found in competing spectroscopy instruments.Jerome® J505 Features: Meets EPA & ATSDR Cleanup Levels Flexible Data Handling Choice of Two Independently Adjustable High Limit Alarms Programmable Auto Sampling Mode Choice of 3 Units of Measurement (nanograms, micrograms, milligrams) Color Display with Easy to Use Menu System Battery Operation for 10+ Hours | Battery Charges in 3 Hours or Less A USB Keyboard can be used for Easy Entry of Locations (optional) Integrated Data Logging Saves all Test Results (excludes search mode)

Atomic Absorption / Emission SpectroscopyAtomic absorption spectroscopy (AAS) and atomic emission spectroscopy (AES) — also called optical emission spectroscopy (OES) — are used to detect the elemental constituents in samples. Both techniques involve the atomization of a sample. Atomic absorption spectrometers may use a flame or furnace to create an atomic vapor of the sample before irradiation with spectral light. Optical emission spectrometers may use a flame, inductively coupled plasma (ICP), microwave plasma (MP) or spark arcs to atomize and excite the sample. At higher excitation energies, electrons can be emitted instead of photons, which can be useful for samples that can’t be atomized and for surface analysis. Explore electron spectroscopy equipment such as Auger spectrometers and photoelectron spectrometers for surface elemental analysis of samples. Find the best atomic absorption, photoelectron and optical emission spectrometers in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Environmental Monitoring and TestingEnvironmental monitoring and testing uses handheld portable analyzers, kits, spectrometers or chromatography systems for air, water, soil, food and other sample testing. Useful features of analyzers such as BOD and COD include portability, easy calibration, automation and sensitivity.  Environmental test kits for pH, water, moisture, etc, should be accurate, sensitive, reliable, fast and easy to use.EPA MethodsEPA methods are procedures approved by the U.S. Environmental Protection Agency for monitoring and analyzing environmental pollutants, including air, water, and soil samples. These methods are critical in ensuring public health and environmental safety. Explore EPA methods and tools in our peer-reviewed product directory; compare products, check reviews, and get pricing directly from manufacturers.Water AnalysisAnalytical methods used to test the purity of drinking water include determining the level of contaminants abides to the level set by the Environmental Protection Agency (EPA).Mercury
