WA-5A
Gaseous Mercury Analyzer
Sensitive, cost-effective and compact
WA-5A is a benchtop CVAAS mercury analyzer designed to measure Total Gaseous Mercury (TGM) from ambient air or gaseous matrices such as natural gas, shale gas, LPG/LNG, etc. It uses the technique of Dual-Gold Amalgamation – CVAAS, which is widely accepted by most established and regulatory methods like ASTM, ISO, and JIS.
Applications
Ambient air | Working environment air | Fuel gas | Natural Gas | Shale Gas | LPG | Other Gaseous Matrices
Methods
ASTM D 5954-98 (2014)e1 | ISO 6978-2:2005 | ISO 20552 | JLPGA-S-07 | Ministry Of Environment Japan (MOEJ) Manual method of measuring hazardous air pollutants
Features
Dual-Gold Amalgamation for Ultra Trace Level Mercury Analysis
WA-series employs the Dual-Gold Amalgamation Technique to ensure excellent recovery of Mercury.
- 1st Gold Amalgamation step happens in the Mercury Collector Tube used for sampling.
- 2nd Gold Amalgamation step happens in the Mercury Collector tube integrated within the WA-5A system. It is also commonly known as Analytical Trap in other official methods.
All Mercury analytes go through dual-gold amalgamation steps, efficiently eliminating any possible interference.
Compact & Lightweight – Only 13 kg & Small Footprint
WA-5A has a dimension of W230 × D460× H390 mm and weighs only 13 kg. Such a compact design makes it more convenient to manage laboratory working space and field operation.
Lower Operation Cost – No Carrier Gas Required & Reusable Mercury Collector Tube
No Carrier Gas Required
WA-5A does not require any carrier gas. It has an integrated room air self-purifying filter to generate the clean carrier gas. It certainly reduces the operation cost and adds convenience for TGM measurement from gaseous matrices, either in the laboratory or in the field.
NIC Mercury Collector Tube
Superior Durability Mercury Collector Tube
All NIC mercury collector tubes are reusable right after the measurement.
The gold-coated sands used in NIC Mercury Collector Tube are synthesized and produced in-house with proprietary technology of more than 40 years.
- Proven robust and long-lasting.
The choice of gold-compound and coating offers a strong affinity and selectivity towards mercury and its resistance toward acid gas and heat, hence resulting in durability and reliability.
- Convenient & Secure All NIC Mercury Collector Tube comes with a glass container with a stopper for convenient, clean, and secure transport when it comes to field sampling, avoiding any cross-contamination.
Superior Detection Limit and Sensitivity – Detection Limit as Low as 0.001 ng
WA-5A is equipped with the state-of-the-art Dual-Cell CVAAS detector with auto-ranging capability, ultimately covering all unknown concentrations within a single measurement. It has a detection limit as low as 0.001 ng and an upper limit linear range up to 1,000 ng. By using this optical system, WA-5A allows a wide range of applications. Ultra-trace mercury analysis can be achieved with ease.
In Compliance with Japanese Manual for Hazardous Air Pollutant Measuring Method
The operating principle of WA-5A complies with a manual measuring method for hazardous air pollutants, established by the Ministry of Environment, Japan.
