NIGP 18060: Isotopes and Their Compounds (Organic and Inorganic)

NIGP 18060 Isotopes And Their Compounds (Organic And Inorganic), an Item code, covers specialty gases and gas mixtures that state and local governments procure for emissions monitoring, laboratory calibration, and industrial process support. The County of Orange, OC Public Works, has recently solicited EPA Protocol calibration and audit gases—carbon monoxide, nitrogen dioxide, sulfur dioxide, and other traceable mixtures prepared to EPA G1 methods—for use in continuous emissions monitoring systems serving air-quality compliance and cogeneration facilities. This code captures the procurement of certified reference gases, calibration standards, and related compounds where traceability to National Institute of Standards and Technology (NIST) reference materials or approved equivalents is a contractual requirement.

Recent activity shows limited but geographically concentrated solicitation. The County of Orange, OC Public Works, is the only issuing body represented in current opportunities, posting two IFBs in the past two months. The more recent and substantive solicitation, IFB 0803068001RE (EPA Protocol Calibration and Audit Gases, due August 10, 2026 at 2:00 p.m.), requires vendors to supply 13 EPA Protocol gas mixtures on a five-year usage agreement with firm, fixed pricing, 24-hour delivery capability, and cooperative-purchasing extension rights to other municipalities and public utilities. The County applies a 5% bid-price preference for Orange County Local Small Business (OCLSB) and Disabled Veteran Business Enterprise (DVBE) certification, with a maximum allowable preference deduction of $100,000. Performance and Labor and Material Payment Bonds are required. All bids must be submitted through the County's eProcurement Portal; Amendment No. 1 was posted October 1, 2026.
