The RA-7000A is NIC's flagship for trace-level Hg in water. The Discrete Direct Purge technique minimises carrier gas consumption and cross-contamination between samples, resulting in low detection limits even in salt and seawater without complex sample preparation.

The system complies with EPA 245.7, EN 1483 and ISO 17852 and is routinely used in environmental monitoring, drinking water control and industrial wastewater analysis. Built-in autosampler and automatic calibration enable unattended overnight operation.
