Process Control and Continuous Monitoring for Process Analytics

Arsenic occurs in large quantities in the earth's crust and in trace quantities in rocks, soil, water and air. PS Analytical have designed the PSA 10.055 Millennium Excalibur to be able to measure Arsenic in solids, sludges and liquids. The instrument combines the advantages of vapour generation techniques which removes most interference with the sensitivity and selectivity of atomic fluorescence spectrometry.

Applications

Technical Specifications

The PSA 50.100 dedicated online CEM analysers for measuring total mercury stack emissions and can be used as a dedicated compliance monitor. The P S Analytical range of mercury continuous emissions monitors (CEMs) is designed to handle all types of industrial and research applications.

Applications

Technical Specifications

The PSA 10.665 is the standard CEM analyser for measuring both total mercury and speciation levels from mercury removal unit's outlets and/or inlets. The unit can be supplied configured for connection to multiple sample points with speciation options.

Applications

Technical Specifications

The PSA 10.680 CEM analyser is designed to give the power of the PSA 10.665 analyser, in a portable compact housing, which allows it to be used as a general purpose monitor, as well as for pilot plant studies.

Applications

Technical Specifications

The PSA 10.226 Online Mercury Analyser builds on our class leading ultra-sensitive atomic fluorescence technology. The system developed utilises syringe-based technology over the standard peristaltic pumps commonly used for sample analysis, reducing reagent consumption and allowing for on board sample preparation.

Applications

Technical Specifications

PSA are proud to present the 10.256 Online Excalibur, for the online analysis of hydride forming elements including: arsenic, selenium, antimony, tellurium and bismuth. The EPA classes the hydride forming elements as toxic and states they must be controlled in effluent streams.

Applications

Technical Specifications

This system vaporises the condensate sample into an argon stream over a heated Amasil® trap. The mercury and mercury compounds are retained in the trap and the hydrocarbons vented to waste. The mercury levels are quantified by transferring them via a clean argon stream to the PSA 10.525 Sir Galahad for analysis.

Applications

Technical Specifications

The PS Analytical 10.536 calibration gas generator can accommodate all these applications and have the capability of being extended to cover any applications which may be required in the future. The system operates on the principle of diluting a saturated source of mercury at known temperature.

Applications

Technical Specifications

The PSA 10.54X is an ExD rated sampling system for hazardous explosive gases. The purpose of the unit is to deliver a representative gas sample to the online mercury analyser in a safe and effective manner. All of the components used in the sampling system are certified to explosive proof rating.

Applications

Technical Specifications

The 10.547 has replaced its well-established and successful predecessor 10.537 offline sampling system. The unit is semi-portable so it can be easily transported between sample points or moved to test different locations. The sampling system can be used for any type of gas and it may be used in hazardous area locations.

Applications

Technical Specifications

The PSA 10.670 is specifically designed to determine total gaseous mercury (TGM) in process gas streams such as natural gas, sour gas, fuel gas, LNG, LPG, butane, ethylene, propylene, hydrogen, carbon dioxide and Syngas. It is also used for measuring total mercury in volatile liquid hydrocarbons and condensates.

Applications

Technical Specifications

The PSA 10.690 Online Hg Preconcentration system is used in conjunction with the PSA 10.670 Online Hg Analyser system and has been specifically designed to monitor the mercury concentration in multiple liquid-phase volatile hydrocarbon samples.

Applications

Technical Specifications

The PSA L225A200 Sampling System is a simple sampling interface. The sample pathway is constructed entirely from inert plastics and glass for water/waste water samples. The system comprises a plug valve, particulate filter, needle valve and glass separator bowl.

Applications

Technical Specifications

The PSA L225A210 Sampling System is a simple sampling interface for higher particulate concentrations. The sample pathway is constructed entirely from PTFE and PFA, with Viton® seals, providing excellent compatibility with a wide range of sample types, including many corrosive samples.

Applications

Technical Specifications

The PSA 50.042 Thermogram consists of a two-stage tubular oven which is used, coupled to a PSA 10.025 Millennium Merlin. Small masses of sample are placed in a sample boat in the first part of the oven which is temperature controlled between ambient and 600°C. An alternative method of speciating mercury in solid samples is thermal desorption with atomic fluorescence spectroscopy (TD-AFS).
