The mobile analyzer system for mercury traces in natural gas is used for quality controls at differing natural gas processing plants.
The Natural Gas Sampling System reduces the primary high pressure of the sample source (up to 200 bar) to a pressure below 1 bar so that the gas can be fed to the continuously operating analyzer: UT-3000 Mercury Ultratracer. This highly sensitive detector is equipped with a GoldTrap allowing for a measuring range of 0.1 ng/mᶟ to 1000 ng/ mᶟ at 10 l sample volume (lowest range). The analyzer features an AutoRange function that adjusts the sample volume according to the mercury concentration of the sample. For safety reasons a flammable gas detector is integrated in the monitoring system.
A customized 4 channel Mercury Monitoring System for Natural Gas (MMS-NG) meeting the special demands of the customer was delivered to Saudi Aramco. One channel is monitoring the gas entering three Mercury Removal Units (MRUs), three channels measure the gas leaving the MRUs. An additional system with two channels surveys the inlet and outlet of a fourth MRU for incurring condensate (mainly higher hydrocarbons).
Owing to the GoldTrap technology the mercury analyzer (UT-3000) integrated in the MMS-NG allows for precise mercury measurements at ultra trace levels. Higher concentrations that can occur in gas or condensate before entering the MRUs can also be measured without any problem. An AutoRange function will automatically reduce or increase the sample volume to be measured. For the above reasons the MMS-NG is able to cover an extremly wide measurement range which makes it the ideal choice for monitoring Mercury Removal Units.
A two-channel Mercury Monitoring System for Natural Gas was delivered to the Uz-Kor Gas Company in Uzbekistan. The MMS-NG controls the inlet and outlet of a Mercury Removal Unit (MRU) in a production plant to ensure the removal of mercury in the natural gas before it is further processed.
Due to the analyzer with GoldTrap technology (UT 3000) the MMS-NG excels in sensitivity and offers a broad measuring range (0.001 µg/m³ ... 50 µg/m³).

Health Canada is the federal department responsible for helping the people of Canada maintain and improve their health. Health Canada runs a laboratory to measure amongst other things the mercury contamination of various foodstuffs.
Health Canada's AULA-254 Gold serves to analyze a multitude of samples rapidly and automatically. With a duration of a measurement cycle of 60 to 180 seconds approx. 20 to 60 samples can be analyzed per hour. A detection limit of <5 pg Hg and a measuring range of 1 ng /l to 50 μg/l (GoldTrap on) enables the AULA-254 Gold to measure mercury concentrations far below the maximum limits permitted (e. g. <0,5 ppm for retail fish).
Easy and uncomplicated operation of the LabAnalyzer allows for a high performance in everyday analytics. The activated carbon filter at the sample outlet prevents any mercury contamination.
The analytical team of the institute for workplace-, social- and environmental medical science uses the LabAnalyzer mainly for rapid and precise determination of mercury in blood and urine samples. In contrast to a typical multi-element AAS the LabAnalyzer is especially designed to measure elemental mercury only, resulting in optimized AAS techology, enhanced performance and a measuring range of 0.01 ppb to 10 ppb.
Our new PA-2-Gold Process Analyzer automatically monitors the mercury concentration in the water of the Ebro River. The instrument has been installed on behalf of the Consorci d'Aigües de Tarragona in an analyzer shelter at the river bank at Tortosa/Tarragona (Spain).
The online measurement supports remedial actions where mercury contaminated sediments are removed from the river bed.The low detection limit of 0.01 ppb required for this task is achieved by employing the highly sensitive UT-3000 detector with amalgamation technique.
Low weight (approx. 5 kg), easy operation and a wide measuring range of 0,1 μg/m³ to 2000 μg/m³ make the Tracker 3000 IP mercury analyzer the ideal choice to localize leakage and resulting mercury contamination in natural gas industries.
