66 -- SXP-300 QUADRUPOLE ELECTRONICS UPGRADE POC William J. Wise, Contracting Officer, 513/366-2025 The USEPA intends to negotiate on a sole source basis, under the authority of FAR 6.302, with Fisons Instruments for the acquisition of an SXP-300 quadrupole which will replace the existing VG12-12 quadrupole in a VG PlasmaQuad Inductively Coupled Plasma Mass Spectrometer (ICP-MS). This upgrade will replace the ''heart'' of the mass spectrometer (quadrupole). The quadrupole is controlled by the analyst via the instrument OS2-based software. This software via an IEEE port communicates with a dedicated control module within the instrument, which converts this set of instructions into a set of digital scanning conditions. This communication is facilitated by proprietary software and highly specialized electronics. Given the proprietary nature of the software and the need for 100% compatibility of both the software and hardware, Fisons Instruments is the only known vendor which can accomplish the required upgrade. THIS IS NOT A REQUEST FOR PROPOSALS. Sources wishing to be considered must submit documentation to the office identified above which establishes the ability to furnish equipment which is fully compatible with the existing ICP-MS system. Documentation must be submitted within 15 calendar days of publication of this notice. (0236)
