Description
The HG-400 series is an automated mercury analyzer that achieves a 0.5 ppt detection limit based on Cold Vapor Atomic Absorption Spectrometer complying with EPA and other standard methods.
Features
High sensitivity - detection limit 0.5ppt.
Perfect for trace levels of mercury detection. The improved optical system and measurement flow path enables the analyzer to reach a lower detection limit of 0.5ppt of Hg.
User friendly - color touch screen.
A large 7.5 inch LCD color touch screen provides all the information that the analyst requires.
 |
Touch lightly on the colorful, clear screen for easy control and analysis. |
Comprehensive data handling
Browse data on PC with LAN connection. Special software is also optionally available.
Expandable and flexible - widest variation of applications
The HG Series is needed in the following settings:
|
• Water Treatment Plants • Laboratories • Steel / Light Metals • Food |
• Government Testing Facilities • Chemicals • Pharmaceuticals • Electrical & Electronics |
HG Series is more cost effective and environmentally friendly
- Smaller sample sizes are needed
- Minimal chemical reagents
- Less waste
Compact design
Built-in printer saves more valuable bench space.

Application Data
Mercuric compounds in sample are broken down and oxidized to mercuric ions by strong acids and oxidant in pretreatment. Mercury is reduced to Hg(0) state by stannous chloride and aerated, then pass through the absorbtion cell to be measured at 253.7nm absorbance based on AAS.
