The new ICP-OES system will be used for the determination of Metals and Trace Elements using EPA Method 200.7. It shall include an Inductively Coupled Plasma Optical Emission Spectrometer with dual axial and radial views that include liquid sample introduction system that handles Nitric and Hydrochloric acids, autosampler with a minimum of 80 sample positions for 50 mL sized tubes with auto dilution capabilities, chiller, computer software, and computer workstation (less monitor and printer). All the latest software, firmware, service packs and licenses shall be included. The instrument must be able to deliver the low concentration method detection limits (MDL) and generate acceptable calibration curves as listed in Table 1. It must follow all instrument operation conditions and meet all method validation and QC requirements specified in EPA 200.7. The quoted ICP-OES system must have the ability to provide proper quantitative and qualitative analysis for the desired analytical method with a minimum reporting (quantitation) limit of 0.1 mg/L Boron, 0.5 mg/L for the 4 alkaline earths / alkali metals (Calcium, Magnesium, Sodium, and Potassium), 0.005 mg/L Iron, and 0.009 mg/L Lithium. The District lab’s current ICP-OES instrumentation can meet the specified requirements. The quoted ICP-OES instrument must be capable to meet or (preferably) surpass these reporting limits and maintain precision with a relative standard deviation (RSD) of less than 10 % across replicate injections. Refer to Table 1 below for additional information regarding desired analytical performance measured by reporting limits (RL) and method detection limits (MDL). It is requested that vendors who offer multiple levels of instrumentation capable of achieving the sensitivity necessary to meet the MDLs listed in Table 1 provide separate quotations for each of these levels. The quotation for each level of instrumentation should clearly distinguish its sensitivity and other major features or upgrades.
