PS Analytical’s Online Arsenic in Liquid Analyser is an aed system for continuous determination of total arsenic and other hydride-forming elements (like selenium, antimony and tellurium) in water and wastewater streams. It combines online sample preparation and conditioning with hydride generation and atomic fluorescence spectrometry (AFS) detection to deliver highly sensitive, real-time arsenic measurements directly from liquid process or environmental streams — eliminating the need for manual grab sampling and offline lab work
Online sampling and conditioning — continuous intake from the liquid stream with integrated digestion/conditioning as needed.
Hydride generation — arsenic in the sample is converted to volatile hydride species.
Atomic fluorescence detection (AFS) — the hydride vapour is quantified using ultra-sensitive AFS, delivering reliable, low-level measurement data.
Continuous data output — results are available in real-time for monitoring, control or reporting.
Real-time, unattended monitoring of arsenic levels in water, effluent and process streams
Ultra-sensitive detection thanks to hydride generation with AFS, suitable for trace and regulatory-driven applications
Integrated online chemistry — sample digestion/conditioning and reagent dosing built into the analyser
Multi-element capability — configurable to measure other hydride-forming elements alongside arsenic
Ideal for compliance and operations in water utilities, industrial wastewater, treatment plants and environmental monitoring programs
Drinking water quality monitoring
Wastewater discharge compliance
Environmental watercourse surveillance
Industrial process water control
Treatment plant performance optimisation
