Features and Benefits
- Simple to operate, fully automated, self validating analyzer;
- Rugged/Versatile design for laboratory and field mobile conditions;
- Ultra low detection limit and highest selectivity;
- Real-time operation mode for air and gases;
- Direct determination of mercury in liquid and solid matrices within 60 seconds (attachment required). No sample preparation, no use of hazardous chemicals or bottled gases ;
- Built-in performance verification test cell and auto zero function;
- Wide dynamic measuring range (four orders of magnitude);
- Controlled by a keypad or a computer via USB interface;
- Data logger for 122 hrs of data acquisition, averaging, and storage;
- Rechargeable battery for up to 12 hours operation
Being combined with an RP-92 Cold Vapor accessory for water and PYRO-915+ pyrolysis attachment for solid sample testing, the instrument is designed to determine mercury content in ambient air, water, soil, natural and stack gases, dental and medical testing and diagnostics, analysis of food and marine life, etc., the mercury detection limits being as low as 0.5 ng/m3 in air and 0.5 ng/l in water.
Analytical Characteristics
