Methylmercury Manual System


Request a Quote

The Brooks Rand methylmercury systems are specifically designed for methylmercury analysis by EPA Method 1630.

Methyl Hg Systems

The standard Brooks Rand methylmercury system combines easy-to-use automated analysis with manual purge and trap for a high throughput, cost-effective system. This system consists of the Model III, the Trap Desorption Module and the GC and Pyrolysis Module for automated trap analysis, along with the manual Methyl Hg Purge and Trap Module. This semi-automated system allows for the simultaneous purging of multiple samples while previously loaded traps are analyzed. The result is a throughput rate of less than 8 minutes per sample. All systems come complete with the Brooks Rand Guru™ Software for system control and peak integration.

Trap Desorption Module

SIMPLE OPERATION – Automates analysis from trap with a single keystroke from Guru™ Software.

CONSISTENCY – Provides simultaneous heating and integration resulting in consistent retention times.

Applications For monomethyl and dimethyl mercury analysis of prepared water samples (by EPA Method 1630), sediment/soil samples or biological samples.
Description Controls heating of methylmercury trap and carrier gas flow through the trap, the GC and Pyrolysis Module, and the Model III detector.

 

 

GC and Pyrolysis Module

CONSISTENCY – The tightly regulated temperature of the GC oven results in consistent retention times and excellent precision.

FLEXIBILITY – Programmable temperature of the GC oven provides analyst flexibility for improved peak separation or faster run times.

Applications For monomethyl and dimethyl mercury analysis of prepared water samples (by EPA Method 1630), sediment/soil samples or biological samples.
Description Controls heating of methylmercury trap and carrier gas flow through the trap, the GC and Pyrolysis Module, and the Model III detector.

 

 

Methyl Hg Purge and Trap Module

VERSATILE – Purge and trap modules are available in a variety of sizes to match your throughput needs and budget.

ANALYST CONTROL – The manual purge and trap module allows ultimate flexibility for the analyst. Sample-specific volumes and dilutions can be carried out to reduce the risks of overloading the system with mercury and to minimize reruns.

Applications For monomethyl and dimethyl mercury analysis of prepared water samples (by EPA Method 1630), sediment/soil samples or biological samples.
Description Performs the ethylation, volatilization, and trapping of prepared liquid samples and controls the purge gas flow rate.
