Cold Vapor Atomic Fluorescence Mercury Analyzer

冷原子荧光测汞仪

Seawater, drinking water and ice cores often hold mercury at levels absorption methods cannot see. This fluorescence analyzer combines gold amalgamation with right-angle PMT detection at 253.7 nm, reaching 0.1–1 ng/L and covering 0.5–100 ng/L. Sample volumes of 10–100 mL are supported. Clean-room sample handling is essential at these levels; ask us for advice.

Detection limit: 0.1–1 ng/L in water
Measurement range: 0.5–100 ng/L
Wavelength: 253.7 nm excitation and emission
Detection: photomultiplier, right angle
Amalgamation: gold trap
