High Sensitivity HPLC Analysis of Contaminants of Emerging Concern (CECs) in Water Using the Agilent 6460 Triple Quadrupole LC–MS System
Tarun Anumol, Sylvain Merel, and Shane Snyder, Department of Chemical & Environmental Engineering BIO5 Institute, University of Arizona
A fast and sensitive method for the monitoring of 36 CEC compounds across the wastewater treatment process has been developed. Most of the compounds have limits of detection and quantitation well below 1 ppb, and method reporting limits (MRLs) range from 0.1 to 15 ppt. Total cycle time is less than 20 min.

Sensitive LC–MS Quantitation of Trace Organic Contaminants in Water with Online SPE Enrichment
Tarun Anumol and Shane Snyder, Department of Chemical & Environmental Engineering BIO5 Institute, University of Arizona; Sheher Bano Mohsin, Agilent Technologies, Inc.
An online SPE method has been developed for the rapid, sensitive, reproducible, and robust analysis of trace organic compounds in water, eliminating large sample volumes and tedious extraction procedures. Methods reporting limits (MRLs) ranged from 0.10 to 15 ppt; recoveries varied primarily from 70% to 130%; most relative standard deviations (RSDs) were below 10%.

Environmental Volatiles Using a Headspace-GC–MSD Analyzer
Mike Szelewski, Agilent Technologies, Inc.
The Agilent Headspace Volatiles Analyzer, SP1 7890-0567, was used for the analysis of environmental volatiles in water. EC reporting requirements, as outlines in the 98/83/EC Directive, were met for all compounds. Calibration from 0.10–20 ppb and reproducibility at the lowest calibration level showed < 10% RSD.

Determination of Iopromide in Environmental Waters by Ion Chromatography-ICP-MS
Armando Durazo, Tarun Anumol, and Shane A. Snyder, Agilent Technologies, Inc.
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).
