The Analysis of Perchlorate by Ion Chromatography/Mass Spectrometry Application
ثبت نشده
چکیده
A method for the determination of perchlorate anion at sub ppb levels using ion chromatography/mass spectrometry (IC/MS) is described. The IC/MS method follows EPA Method 314 methodology originally developed for IC with conductivity detection at the single ppb range [1]. The IC/MS method is not affected by the addition of the interference matrix described in Method 314 on perchlorate recoveries throughout the measurable range. Typical recoveries are 90%–105% at the 0.5 and 1-ppb level in synthetic drinking and waste waters with the method detection limit (MDL) less than 100 ppt.

Analytical method for perchlorate in water by liquid chromatography-mass spectrometry using an ion exchange column.
A practical analytical method was developed for the routine analysis of perchlorate in environmental and drinking-water samples by liquid chromatography-electrospray ionization mass spectrometry (LC/ESI-MS) using an anion exchange column. By using (18)O-enriched perchlorate as an internal standard, the limits of quantification of perchlorate determined by tenfold of the signal-to-noise ratio an...
متن کاملAnalysis of perchlorate in human urine using ion chromatography and electrospray tandem mass spectrometry.
Because of health concerns surrounding widespread exposure to perchlorate, we developed a sensitive and selective method for quantifying perchlorate in human urine using ion chromatography coupled with electrospray ionization tandem mass spectrometry. Perchlorate was quantified using a stable isotope-labeled internal standard ((18)O(4)-perchlorate) with excellent assay precision (coefficient of...
متن کاملDetermination of perchlorate in infant formula by isotope dilution ion chromatography/tandem mass spectrometry
A sensitive and selective isotope dilution ion chromatography/tandem mass spectrometry (ID IC-MS/MS) method was developed and validated for the determination of perchlorate in infant formula. The perchlorate was extracted from infant formula by using 20 ml of methanol and 5 ml of 1% acetic acid. All samples were spiked with (18)O(4) isotope-labelled perchlorate internal standard prior to extrac...
متن کاملDetermination of perchlorate at trace levels in drinking water by ion-pair extraction with electrospray ionization mass spectrometry.
Perchlorate has been added to the U.S. Environmental Protection Agency's Drinking Water Contaminant Candidate List (CCL). The present work describes the analysis of perchlorate in water by liquid-liquid extraction followed by flow injection electrospray mass spectrometry (ESI/MS). Cationic surfactants, mostly alkyltrimethyl-ammonium salts, are used to ion-pair aqueous perchlorate, forming extra...
متن کاملQuantitative analysis of perchlorate in extracts of whole fish homogenates by ion chromatography: comparison of suppressed conductivity detection and electrospray ionization mass spectrometry.
The perchlorate anion (ClO4-) is an anthropogenic contaminant of increasing concern in water supplies, and has been shown to disrupt thyroid activity. Most perchlorate analyses are currently carried out by ion chromatography (IC) with suppressed conductivity detection (SCD). While this procedure has been demonstrated to provide acceptable performance for analysis of water samples, the determina...
