This application note describes the use of the Agilent 730-ES to carry out the US EPA/CLP compliant analysis of water samples. The instrument features true simultaneous measurement, allowing fast and accurate analysis of target analytes in water samples. It also has features such as extended linear range and long-term stability.
The document details a method using the Agilent 730-ES with a custom-designed CCD detector and an Agilent Switching Valve System (SVS) with SPS3 autosampler. The setup allows for simultaneous measurement of up to 1,000 elements from microgram per litre to percentage levels.
The note provides specific instrument operating conditions, including plasma gas flow at 15 L/min and auxiliary gas flow at 1.5 L/min. It also lists Method Detection Limits (MDL) and Contract Required Detection Limits (CRDL) for various elements such as Ag, Al, As, Ba, Be, Ca, Cd, Co, Cr, Cu, Fe, K, Mg, Mn, Na, Ni, Pb, Sb, Se, Tl, V, and Zn.
