Direct thermal decomposition mercury analyzer
Affordable, high-performance & compact benchtop direct mercury analyzer
Affordable robust design with a wide measurement range
Engineered for affordability, with easy-to-use manual boat loading and a sturdy “quick twist” load lock, the rugged MA-3 Solo is simple to operate and delivers a wide measurement range of 0 to 10,000 ng with quick analysis times ranging from 5 to 12 minutes.
Inexpensive operation – no gases or consumables required
MA-3 Solo was designed to be as simple to use as possible. Unlike other systems that require purified oxygen gas, purified air is used as the combustion and carrier gas. This design concept makes the instrument perfect for field portable operation or for use in mobile laboratories. The ceramic sample boats are easily cleaned for reuse. No gas requirement and reusable boats keep operating costs low.
Advanced optics for superior sensitivity and stability
Employing a high-quality thermally stabilized Hg-discharge lamp that emits a very strong, stable line emission at 253.7 nm eliminates the need for any intensity-robbing optical filtering of the source. Two rugged semiconductor detectors provide the quantitative and reference measurements, ensuring a long lifetime of trouble-free operation. Other systems use inexpensive 50% transmittance mirrors to redirect the light source, but this reduces the intensity, lowering sensitivity. Instead, MA-3 Solo uses high quality optical gratings to redirect the full intensity through the sample cell and to the reference detector, for superior sensitivity and stability.
Real time continuous diagnostics
MA-3 Solo’s software continuously monitors key diagnostics, such as all heater temps, flow rates, valve actuations, and voltages. This allows the software to automatically prompt the user if there is an issue, and it also allows for quick and easy troubleshooting for maximum uptime and reliability.
Compact, lightweight design for portability
Engineered for portability, the MA-3 Solo has built-in ergonomic handles and weighs just 13 kg (~28 lbs). It can run on any standard single-phase wall power, from 100 to 240 VAC (50/60 Hz). The rugged design is perfect for field operation or for use in mobile labs.
Windows based and user friendly graphical software
Running under the Microsoft Windows operating system, the MA-3 Solo’s modern software is intuitive to use and provides a real-time graphical representation of the measurement status.
