SPECIFICATIONS

INDUCTIVELY COUPLED PLASMA MASS SPECTROMETER

ICP-MS)

The Orange County Utilities Central Laboratory is soliciting bids for one (1) state-of-the-art Inductively Coupled Mass Spectrometer (ICP-MS) computer-controlled bench top instrument that offers maximum performance and versatility. This instrument will be used for analysis of trace metals in environmental samples, including potable waters, environmental waters, and bio-solids. Due to space limitations, the County requires a benchtop instrument. The ICP-MS instrument with a dedicated data system shall meet or exceed the specifications listed below.

The Perkin Elmer NexION 2200, the ThermoScientific RQPlus and the Agilent 7900 ICP-MS have been approved by the County as acceptable.

(quoted). Specifications below.

ESI prepFAST

24.1 Auto calibration from a single stock solution

24.2 Variable in-line dilution performed with a mixing valve up to 400x.

24.3 QC Auto dilution of calibration over range or internal standard out of range.

24.4 The FAST system offers many advantages for analyzing a variety of sample types and ICPMS including:

24.4.1 Lowers reagent cost by using lower concentrations of internal standards.

24.4.2 Better precision.

24.4.3 Lower cost of consumables and routine maintenance: torch, nebulizer, cones, pump oil.

24.4.4 Reduced deposition on cones, etc.- due to smaller sample sizes minimizes drift.

24.4.5 Lower facilities cost with shorter run times for less consumable usage-peripump tubing, Ar gas, etc.

24.4.6 Improves sensitivity.

24.4.7 Lowers oxides

24.4.8 Cleaner, faster washout, reduces sample carry-over.

24.4.9 Eliminates peristaltic pump memory effects by sample never touching peripump tubing.

24.4.10 Dual rinse station improves rinse out and reduces blank contamination.

24.4.11 Fewer QC failures.

24.4.12 Faster stabilization time.

24.4.13 Optional online constant dilution with micro-peripump.

24.4.14 Can add volatile analytes such as Hg to ICPMS methods.

24.4.15 High speed sample loading minimizes sample uptake time.

24.4.17 Pre-loaded FAST and ICPMS methods for rapid implementation included.

24.4.18 Modular design enables multi-application flexibility (with plug and play ease-of-set-up).

24.5 The prepFAST offers many advantages as well to sample preparation and analysis including:

24.5.1 Software control and functionality: the prepFAST software allows for flexibility in method development due to the unique functions available in the software.

24.5.2 Multiple syringe system: The prepFAST utilizes the S400V which contains multiple syringe modules with various barrel volumes for precise dilution up to 400X.

24.5.3 Priority dilution: After a run of samples, the user can simply select the over-range samples from the list and then rerun without moving samples, rewriting shorter methods, etc.

24.5.4 Auto calibration: The prepFAST allows for calibration from a high standard with the user simply selecting the calibration points they desire and the prepFast does the rest.

24.5.5 Inline dilution: The prepFAST mixes/dilutes the sample inline thereby eliminating the need to take an aliquot of the sample and diluents and deposits it into another tube that could be the source of con-tamination.

24.5.6 The prepFAST automatically mixes the sample with the internal standard accurately.
