Mercury Vapor Analyzers: Finding the Right Fit for Your Needs

Arizona Instrument LLC
18 Nov 2014

There are many different technologies which can be used to detect mercury, and some may be more appropriate in certain environments than others. This paper explains the differences between gold film sensors, atomic absorption spectroscopy and atomic fluorescence spectroscopy, focusing on how these technologies work, what interferences they have and how sensitive they are to low levels of mercury vapor.

Jerome® J405 Mercury Vapor Analyzer

Arizona Instrument LLC

The AZI Jerome® J405 portable mercury vapor monitor is redefining the portable mercury vapor analyzer market. Significant performance enhancements and modern communications capabilities have been combined to create a new option for mercury spill detection and cleanup analysis. Like its 411 & 431X predecessors, the J405 utilizes the industry-proven, inherently stable and reliable gold film sensor technology and simple, one-button operation. The ergonomically-designed handle, lighter exterior case and significantly lower detection capabilities (0.5 μg/m3) have re-set the bar for portable and easy, low-level mercury detection instrumentation. The larger display, on-board data logging, auto zeroing, and battery-powered sensor regeneration will simplify operation and maintenance in the field. Menu-driven programming, USB data communications and SCADA compatibility via 4-20 ma output further enhance data retrieval, storage and reporting.Applications:  Mercury Spill Response & Cleanup  Mercury Exclusion Testing  Facility Monitoring  Source Surveys  Hazardous Waste Sites  Fluorescent Lamps Disposal & Recycling  Worker Safety  Landfill Monitoring  Exhaust Duct Monitoring  Plant Environment Monitoring: light bulbs, mercury switches equipment  Fish (Heated)

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.Fluorescence SpectroscopyFluorometers and spectrofluorometers (also called fluorescence spectrometers) are used to measure the intensity and wavelength of fluorescent light emitted from a sample after excitation by illumination. Spectrofluorometers utilize monochromators to select the desired wavelengths, whereas filter fluorometers employ a set of filters. Spectrofluorometers for measuring steady-state fluorescence and lifetime fluorescence (or time-resolved fluorescence) are available, as well as fluorescence microscopes and microplate readers. Find the best fluorescence spectroscopy products 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.MercuryAirborne PollutantsAirborne pollutants are particulates, biological molecules or other harmful materials that exist in the atmosphere. These pollutants are known to cause harm to health and the environment. Examples include persistent organic pollutants (POPs), carbon monoxide, sulfur oxides, and nitrogen oxides.
