Thus, it can cover a wide range of matrices and applications.

By utilizing the delicate temperature controls in the sample heating furnace and its whole pathway, the mercury’s memory effect can be minimized and prevented. This will reduce cross-contamination and carryover that often occur in mercury analysis and lead to highly accurate and precise mercury measurement results.

Very User-friendly Operating System

The analysis operation in MA-3000 is simple and straightforward and NO prior experience is needed. Users only need to weigh the desired solid or liquid sample onto the ceramic sample boat and select the right thermal decomposition method.

MA-3000 Mercury Analyzer

SCRD is a Reducing Vaporization attachment to be used with MA-3000, consists of one dedicated autosampler and one reagent dispenser.

Aqueous samples such as drinking water, tap water, lake water, and river water have relatively low mercury levels. Thus, MA-3000 with SCRD provides users with the option to analyze such samples at a low sub-ppb level using the reducing vaporization method that uses a higher sample volume (5 mL), providing a much better detection limit.


Drinking Water | Tap Water | Lake Water | River Water


USEPA 245.1, 245.2, 245.5, 7470A, 7471B  |  ASTM D 3223-17  |  EN 1483  |  APHA 3112  |  JIS K0102  |  ISO 12846

  • Firstly, the samples have be manually pre-chemically treated (acid digested), to oxidize all forms of mercury into Hg2+.
  • From here, for measurement, a reducing agent or reductant is used to reduce Hg2+to Hg0. With SCRD, it helps to auto-dispense the reducing agents, H2SO4 and SnCl2 , into samples located in the autosampler.

Sn2+ + Hg2+ -> Sn4+ + Hg0

  • Carrier air from MA-3000 purges the sample solution starts the reduction, converting all Hg2+ into Hg0  and transfer Hg0 out of the sample tube into the CVAAS detector in the MA-3000 for measurement. The whole process takes 2 to 3 minutes to complete a measurement.

With this combination, users have the versatility to utilize two techniques on a single platform – Direct Thermal Decomposition and Reducing Vaporization, expanding the coverage on a wide range of mercury analysis needs.


MA-3000 Mercury Analyzer

RH-MA3 is a Gas Analysis attachment to be used with MA-3000 for mercury measurement of gaseous matrices sampled onto mercury collector tubes. Total Gaseous Mercury (TGM) is one of the main target analytes for gaseous matrices. This analyte can be collected using the NIC Mercury Collector Tube and followed by direct tube-desorption analysis using RH-MA3 – a Gas Analysis Attachment in MA-3000.


Ambient Air | Working environment | Fuel Gas | Natural Gas | LPG


ASTM D 5954-98 (2014)e1  |  ISO 6978-2:2005  |  JLPGA-S-07 | ISO 20552 |  Ministry Of Environment Japan (MOEJ) Manual method of measuring hazardous air pollutants

The RH-MA3 attachment allows the user to directly analyze mercury that is collected onto a NIC N160 Mercury Collector Tube.


Mercury Collector Tube and a sampling pump are used for on-site sampling of ambient air. For sampling of hydrocarbon gases (e.g., natural gas or LPG), a Tedlar bag is needed to collect the gas and a sampling pump is needed to transfer the gas onto the Mercury Collector Tube, with a gas meter to measure the sampling volume due to difference in specific gravity of the gas sample.


  • The tube is first placed into the RH-MA3 heater compartment, where it is desorbed to release the amalgamated Hg. Any traces of acidic gases and moisture will be removed by the scrubber and Peltier-chilled dehumidifier, respectively.
  • The mercury is recollected and purified at a second Gold Trap in RH-MA3.
  • The second trap is then heated, liberating all purified and concentrated mercury into the CVAAS detector of MA-3000 for measurement.

All Mercury Collector Tube can be reused after measurement in MA-3000.

MA-3000 Mercury Analyzer

The MA-3000 SCRD / RH-MA3 Combo allows users to operate all three different mercury analytical techniques – Direct Thermal Decomposition, Reducing Vaporization and Tube-Desorption for all types of sample matrices (solid, liquid, and gaseous) in a single platform and instrument. Switching between the techniques is automated by the system software, all within the operator’s finger-tip.
