Analytical results provided by SLTC to CSHOs are often used as the basis for citations and these results must be accurate, precise, and defendable in court proceedings. 2. SCOPE OF WORK Vendor is to supply Salt Lake Technical Center with Inductively Coupled Plasma combined with Mass Spectrometry (ICP/MS) instrumentation including collision and reaction cell technology for interference mitigation; instrument is to be used for measurement of metal ions in acidic aqueous solutions derived from industrial hygiene sampling. The entire ICP/MS instrument system must be in new (unused) condition. 3.

The pumping system shall have enough capacity to reach operating vacuum from ambient atmosphere in less than 20 minutes. In the event of vacuum failure, the entire vacuum system is to be automatically back-filled by inert gas to preserve the cleanliness of the system. Turbo-molecular vacuum pump must be purged by an inert gas during operation to prevent damage by reactive gases and/or corrosive vapors. Auto-sampler The instrument package must include an auto-sampler with control software and sample dilution capability - Cetac model SDS 550 w/ASX 520, or equivalent. The auto-sampler must have a completely metal free fluid path and its own peristaltic pump for supplying rinse to the sampling probe.

The RF generator and load coil must have an internal cooling system that effectively provides stable temperature control. Safety interlocks throughout the system shall provide safe shut down of the generator without damage to the instrument in the event of power failure. In addition, all failure events must be recorded to an electronic error file and must include event description, time and date.

The cell shall be capable of reducing the intensity of isobaric and polyatomic interfering species by up to 8 orders of magnitude. There must be a provision to prevent non-ionized matrix components from entering the cell (thus eliminating cell contamination) and prevent photons from reaching the detector.

The vendor must specify in the bid the ability to remove following interferences: ArAr interference on Se-78 ArC interference on Cr-52 MoO interference on Cd-111 CaO interference on Ni-60 ArO interference on Fe-56 ClO interference on V-51 ArCl interference on As-75 ArNa interference on Cu-63 Quadrupole A high-performance quadrupole mass analyser shall be provided. Stability of the quadrupole mass calibration and resolution shall be maintained by having critical parts of the quadrupole power supply temperature controlled. The system should give the user the option to run selected isotopes at a user defined, alternative resolution setting. Safety interlocks shall cut off the power to the quadrupole under any instrument condition that could cause damage to the quadrupole or detector assembly.
