Agilent 710-ES is a US EPA compliant water sample analysis instrument. It uses a megapixel CCD detector for fast, precise and accurate analysis.
The document details the analysis of environmental water and soil/sediment samples for 23 target analytes, including mercury and cyanide, following US EPA Contract Laboratory Program (CLP) guidelines. It specifically focuses on the use of the Agilent 710-ES Inductively Coupled Plasma-Optical Emission Spectrometer (ICP-OES) equipped with a megapixel CCD detector and the SPS3 autosampler.
The text outlines the instrumentation setup, including gas flows and nebulizer settings, and lists the specific calibration and quality control solutions used from Inorganic Ventures. It presents data on Method Detection Limits (MDL) and Contract Required Detection Limits (CRDL) for various elements, demonstrating that the instrument meets the specified requirements. Additionally, the document covers linear range analysis, inter-element correction verification, and laboratory control sample recovery results.

The instrument analyzes 23 target analytes including mercury and cyanide, as well as elements like Ag, Al, As, Ba, Be, Ca, Cd, Co, Cr, Cu, Fe, K, Mg, Mn, Na, Ni, Pb, Sb, Se, Ti, V, and Zn.
The US EPA recommends that the maximum silver concentration is limited to 2 mg/L.
A replicate read time of 30 seconds was found to be sufficient to meet the contract required detection limits.
