P S Analytical Limited products

Online wastewater analysis for the determination of Mercury (Hg), Arsenic (As) & Selenium (Se), at trace concentrations, using Atomic Fluorescence Spectrometry. Hg, As & Se are considered environmental priority pollutants and the determination of these metals in wastewater from industrial sources is a challenging application. In recent years wastewater treatment plants have been installing technologies to capture and remove the metals. The efficiency of these treatment processes needs to be monitored using accurate analytical systems.

Active air sampling for the determination of mercury in ambient air. The PSA Air Sentinel is an unattended ambient air, active sampling device that provides sampling with, an accurate air volume for mercury in air studies. The ambient sample is actively carried over PSA’s gold Amasil™ traps to preconcentrate any Hg that may be present. The air is actively pumped through the Air Sentinel using a calibrated micro vacuum pump. Depending on the location remoteness and other requirements the system may be powered by a using a DC power pack, or the integrated rechargeable battery pack with solar panel options.
