1. GENERAL These specifications are for the purchase of one replacement ICP mass spectrometer (UNIT) for the South Cary Water Reclamation Facility, which is currently using NexION 300X model. The selected replacement UNIT shall adhere to all the following minimum specifications. a) The specifications were not written to intentionally eliminate any one bidder. The specifications were prepared to meet the requirements of equipment dimensions, system compatibility, Town standard operating procures and internal controls. b) Other alternatives to the UNIT will be considered but the equipment shall be reviewed and preapproved by the Town as equivalent during the Question-and-Answer Period. (see schedule on page 2). • The bidder shall send their question to the bid contact where it will be reviewed and answered in the form of an addendum at the conclusion of the Q&A Period. c) Shipping, handling and any other appliable fees shall be submitted separately on the Bid submittal form. Any price discrepancies outside of the submitted bid will be at the bidders’ expense. d) Installation & Startup costs shall be submitted as a separate line item on the bid submittal and not factored into the item price. Any price discrepancies outside of the submitted bid will be at the bidders’ expense. e) The equipment manufacturer shall have a minimum of five (5) years of design and manufacturing experience with ICP mass spectrometer. f) A copy of the instrument hardware manual, specification sheet and dimensional drawings must all be submitted with the bid. A) GENERAL REQUIREMENTS: The UNIT must be able to meet method performance standards and minimum MDL and PQL requirements not only for the current permit and long term monitoring program (LTMP), but also account for the possibility of lower requirements in the next 10 years. For economical purpose, Town plans to continue using the existing computer (Windows 10 Enterprise LTSC V1809, 64-bit operating system, Intel Core i5- 8500 CPU @ 3.oo GHz, RAM 8.00GB), auto-sampler (SC2-DXS, Elemental Scientific Inc.), and chiller (DuraChill, PolyScience). Therefore, the proposed UNIT shall be compatible with the existing items. Exceptions may be granted with the proposed new computer, auto-sampler, and/or chiller depending on the bid price. The UNIT/system must include the following components: a) All items and accessories for automated turn-key operations b) RF plasma ion source c) Maintenance free RF coil d) Liquid sample introduction system e) Triple cone interface f) Quadrupole Ion Deflector g) Quadrupole with a 90 degree ion beam path h) Quadrupole-based Universal Cell to eliminate spectroscopic interferences using either collision gases with KED or pure reaction gases such as ammonia and oxygen for DRC Mode with Dynamic Bandpass Tuning i) Quadrupole mass filter j) Mass range must be to 285 amu or greater k) Simultaneous dual stage discrete dynode detector l) System must include all items and accessories for automated turn-key operations (instrument, cables, software(s), etc.). Note Town plans to continue using the existing computer, auto-sampler, and chiller. m) Full system must use single-phase power and remains in specification as laboratory temperature varies 10 to 35°C at up to 2°C per hour. n) System must be fully compliant with US EPA methodology for Method 200.8 and Method SW 846- 6020 o) UNIT/system must have a full color plasma view window for useful visuals on the sampler cone, plasma color and injector tip p) UNIT must be a bench top design with a utility free rear, enabling it to be placed directly against the wall (some service procedures may require movement from wall) q) Maintenance free system must not require any periodic maintenance (cleaning) or replacement of: a. Extraction lenses b. Focusing lenses c. Collision, collision/reaction, or universal cell d. Main filtering quadrupole for the system’s lifetime by the user or the manufacturer’s service engineers.
