Determination of Trace Anions in High Purity Waters by High Volume/Direct Injection Ion Chromatography
INTRODUCTION There has been considerable interest in the determination of anions at trace levels by IC. For example, the Electric Power Research Institute (EPRI) has established IC as the analytical technique for determining sodium, chloride, and sulfate down to 0.25 μg/L (ppb) in power plant waters. For high-purity water used in semiconductor processing, the Semiconductor Equipment and Materia...
متن کاملIndirect determination of trace amounts of fluoride in natural waters by ion chromatography: a comparison of on-line post-column fluorimetry and ICP-MS detectors.
An alternative method for the determination of trace levels of fluoride in drinking and sea-water samples is presented. It is based on the formation of the aluminium monofluoride complex in excess of Al3+ and separation of the two species formed (AlF2+ and Al3+) in a small (5 cm long, CG2) ion exchange guard column. The final determination is accomplished by both ICP-MS specific detection and p...
متن کاملTrace ion chromatography
Due to the increased sensitivity of instrumentation, analytical detection limits can now reach ng/L (ppt) levels on a routine basis, and even pg/L (ppq) levels under certain conditions. Confidence in the data recorded for these trace analyses relies on the control of several conditions and parameters. Besides the technical performance of instruments, careful sample handling and reagent purity a...
متن کاملDetermination of iopromide in environmental waters by ion chromatography - ICP - MS
The determination of iopromide in environmental waters has been accomplished using an Agilent 7700x ICP-MS coupled to an Agilent 1260 LC. The use of High Matrix Introduction (HMI) technology allows for prolonged operation with a sodium hydroxide (NaOH) eluent, and the Octopole Reaction System (ORS3) in helium gas mode reduces polyatomic interferences on iodine (m/z 127). Determination of ioprom...
متن کاملAnalysis of haloacetic acids, bromate, and dalapon in natural waters by ion chromatography-tandem mass spectrometry.
The addition of oxidants for disinfecting water can lead to the formation of potentially carcinogenic compounds referred to as disinfection byproducts (DBPs). Haloacetic acids (HAAs) are one of the most widely detected DBPs in US water utilities and some of them are regulated by the US Environmental Protection Agency (USEPA). The present study developed a method to analyze all the compounds in ...
