Dionex DX-500 Modular System for Anion Determination in Water

The common anions, F-, Cl-, Br-, NO2-, NO3-, HPO42- and SO42- are determined by ion chromatography using the Dionex DX-500 Modular System with IONPAC AG14 Guard Column and IONPAC AS14 Analytical Column. Analyses are performed in accordance with the EPA Method 300.0, which is approved for drinking and environmental water samples. Detection Limits for Inorganic Anions ranges from 0.1 to 100 mg/L for most inorganic anions.

PSA Excalibur Atomic Fluorescence Spectrometer

Elements easily converted into hydrides (e.g., AsH₃) can be readily analyzed by Atomic Fluorescence Spectrometry (AFS). In addition to the determination of total concentrations we also provide speciation of arsenic (arsenite, arsenate, MMA and DMA) and of selenium (selenite and selenate). This is done via species separation in an ion exchange column prior. Detection imits are in the 1 ppb (µg/L) range.
