Product Description

The NIC RA-7000F is a highly sensitive mercury analyzer that utilizes Cold-Vapor Atomic Fluorescence Spectrometry (CVAFS) technology combined with Discrete Direct Purge (DDP) Technology. It is engineered for ultra-trace level mercury analysis in water samples, achieving an exceptional detection limit of ≤ 0.01 ppt.

Key features and capabilities include:

• TRIFLEX Operation Mode: This innovative feature offers three distinct operational modes (Direct, Gold Amalgamation, and Dual) in a single instrument, providing unparalleled flexibility to comply with various methods like USEPA 1631E, USEPA 245.7, and ISO 17852 without requiring hardware changes.

• Minimal Mercury Memory Effect: The core Discrete Direct Purge (DDP) technique isolates each sample in its own tube, virtually eliminating cross-contamination and carryover for reliable and accurate results, even after measuring high-concentration samples.

• Modular & Automated Design: The system pairs seamlessly with the SANPRA™ 3F autosampler for fully automated, high-throughput analysis, and features Flexi Connect to easily adapt to other attachments like a large-volume impinger.

• Built-in Contamination Control: An integrated RAir™ Air Filtration System removes over 90% of ambient airborne mercury, maintaining a clean analytical environment essential for ultra-trace detection.

• Advanced QC and Software: The system includes sophisticated RA7000FWin software with an optional EPA QC Plug-in for automated, audit-ready quality control that ensures compliance with stringent regulatory method requirements.
