Mercury Analyzers for Process Analytics

Mercury analysers are now an essential tool for all analytical laboratories as mercury which is extremely toxic to humans is a major contaminant throughout our environment. The PSA 10.025 Millennium Merlin mercury analyser is designed specifically for the analysis of mercury in all types of samples. The analyser combines the advantages of vapour generation techniques which removes most chemical interferences with the sensitivity and selectivity of atomic fluorescence spectrometry which allows mercury analysis down to sub ppt detection limits with 107x linearity.

Applications

Technical Specifications

The PSA 10.035 Millennium Merlin 1631 was developed for the determination of mercury at low levels and specifically to be compliant with EPA Method 1631 for mercury in drinking water. The instrument is essentially the same as the PSA 10.025 Millennium Merlin but with the inclusion of a gold trap prior to the detection step. The system uses continuous flow vapour generation, but the generated mercury vapour is passed over a gold trap where the mercury is preconcentrated.

Applications

Technical Specifications

The 10.045 Millennium Merlin Cold Vapor AAS System was developed to be compliant with EPA Cold Vapor methods stipulating the use of atomic absorption for the determination of mercury at low levels. The system is based on continuous flow generation but utilises atomic absorption as the detection method. Detection levels in sub ppt levels are readily available.

Applications

Technical Specifications

The PSA 10.125 Millennium Merlin Satellite is a free standing unit which when connected to the PSA 10.055 Millennium Excalibur allows users to be able to measure mercury in addition to the hydride forming elements (arsenic, selenium, antimony, bismuth and tellurium) down to trace levels without having to purchase a separate mercury analyser.

Applications

Technical Specifications

The PSA 10.525 Sir Galahad analyser is specifically designed for measuring mercury in gaseous samples at both online and offline installations. Sampling is via a dual purge and trap arrangement incorporating specific Amasil® traps operating in either a continuous or remote operation. The analyser complies with both ISO 6978:2 and ASTM 6350-98 methods for measuring mercury in natural gas.

Applications

Technical Specifications

The PSA 10.570 UV Cracker utilizes the energy from a low pressure mercury lamp to enhance the rate of certain reactions. This allows reaction times to be reduced from 30 minutes to 1 minute, so allowing reactions to be carried out online. This can either be for the online determination of total mercury or for post column derivitisation in the speciation analysis of mercury or arsenic using atomic fluorescence.

Applications

Technical Specifications

Integrated High Performance Liquid Chromatography Pump, High Pressure Sample Injection Valve, UV Lamp Oxidising and Heating/Cooling Module. The 10.820 Modular Interface (MI) extends the range of applications to any Millennium Merlin or Excalibur Instrument. The MI is configurable and may include LC pump, injection valve, UV cracker, heater and cooling modules.

Applications

Technical Specifications

The M025K006 Speciation Starter Kit connects to either the PSA 10.025 Millennium Merlin or PSA 10.055 Millennium Excalibur systems to create an ideal detection system for speciation purposes. The kit provides a 0-41V output, allowing the signal from the Millennium system to connect to any chromatography software.

Applications

Technical Specifications

The PSA S570U100 heated speciation coil is an accessory which allows samples or reagents to flow through either a heater or a heater then UV coil to enhance the rate of certain reactions. This allows reaction times to be reduced from 30 minutes to 1 minute, thus allowing reactions to be carried out on line.

Applications

Technical Specifications

The PSA S570C100 is an accessory specifically designed to be used with the PSA S570U100 Heated Speciation Coil or the PSA 10.570 UV Cracker in speciation studies of organomercury, organoarsenic or organoselenium compounds and the automatic digestion for total mercury analysis using vapour generation atomic fluorescence spectrometric detection.

Applications

Technical Specifications

The PSA M035S100 Scarifier has been specifically designed to extend the range of samples analysed with the PSA 10.035 Millennium Merlin 1631 to include gaseous samples. Gaseous samples such as air and natural gas are collected on Amasil traps and brought to the Scarifier.

Applications

Technical Specifications

The G525S100 Air Sentinel is an unattended ambient air, active sampling device that provides sampling with an accurate air volume for mercury in air studies. The ambient sample is actively carried over PSA's gold Amasil™ traps to preconcentrate any Hg that may be present.

Applications

Technical Specifications

The PSA M035K003 Solid Sampler Kit has been designed for the sampling of solids such as soils for the determination of elemental mercury. The system includes argon purging controls purging vessels and transfer buckets for connecting Amasil™ traps.

Applications

Technical Specifications

The PSA N118A200 injection valve module is designed to be used as part of an automated speciation system. The N118A200 is a stainless steel, 6 port 2 position air actuated injection valve mounted in a module for stability. The internal surfaces have been coated to ensure all contact surfaces are inert.

Applications

Technical Specifications

The Millennium Excalibur System is a very sensitive system for the determination of the hydride forming elements such as As, Se, Sb, Te and Bi. The M055M010 allows users to fully optimise the reagent conditions by dropping the reductant concentration below the level required for operation of hydrogen flame in the Millennium Excalibur.
