Gaseous Mercury Analyzer
Ultra-sensitive, Cost-effective and Compact
WA-5F is a benchtop Cold Vapor Atomic Fluorescence Spectroscopy (CVAFS) mercury analyzer designed to measure Total Gaseous Mercury (TGM) from ambient air and gaseous matrices such as natural gas, shale gas, LPG/LNG, etc. It uses the technique of Dual Gold Amalgamation – CVAFS, which is widely accepted by most established and regulatory methods like ASTM, ISO, and JIS.

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-5F 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
WA-5F has a dimension of W230 × D460× H390 mm and weighs 13 kg, which is compact for most laboratories. Thus, making it convenient to bring WA-5F field operations.
Superior Detection Limit and Sensitivity – 0.1 pg and Better
WA-5F is equipped with an ultra-sensitive CVAFS detector, and it can achieve a detection limit down to less than 0.1 pg.
This extremely selective and sensitive detector is the best choice for ultra-trace measurements in the parts-per-trillion and sub-parts-per-trillions (ppt) levels of applications.
Using purified Argon as the carrier gas, the CVASF detector is stable and clean, making ultra-trace level of mercury analysis easy.
Lower Operation Cost – Low Gas Consumption & Reusable Mercury Collector (Sampling) Tube
Low Consumption of Argon Gas
Purified Argon gas is mandatory for CVAFS operation. WA-5F has its self-purified room air as a carrier gas source to purge and transfer Mercury between the amalgam tubes and purification processes. Argon gas is only used during the detection sequence. This significantly reduces the consumption and operation cost comparing to other commercial AFS system. It is an added benefit and convenience of employing WA-5F 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 Tubes 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 offer 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 Tubes come with a glass container with a stopper for convenient, clean and secure transport when it comes to field sampling, avoiding any cross-contamination.
High Productivity & Versatile – Multi Choices of Autosampler
WA-5F is highly versatile, where it can be used as a standalone unit or operated with different autosampler options.
