This is a City of Amarillo, Texas Purchase Specification (Specification No. WWT-82) for Specialty Laboratory Gases for the Environmental Laboratory in the Wastewater Treatment Department. The specification aims to establish an annual contract for laboratory gases, with the goal of providing year-round, uninterrupted service for operating lab equipment. The document outlines detailed requirements for gas purity grades, cylinder sizes, and fill levels for various gases including Nitrous Oxide, Acetylene, Hydrogen, Nitrogen, Argon/Methane, Helium, and Liquid Nitrogen. The city has consulted eight potential vendors: Matheson Gas Products, Air Products, U.S. Airgas, Big 3 Industries, Cen-tex, Scott Specialty Gases, Airco, and Alphagaz.

The specification provides comprehensive details on cylinder specifications, including shoulder height high-pressure steel cylinders, acetylene cylinders, liquid containing vertical gas pack type cylinders, and argon cylinders. The city requires specific purity levels ranging from 99.0% to 99.9999%, with precise definitions for each gas type. Ordering and delivery terms stipulate maintaining one active cylinder on-line with a full backup cylinder, and vendors must respond within two weeks of a call. The document also addresses cylinder rental pricing, with the city noting that prices (including rental prices) typically remain valid during contract extensions. A special note highlights the laboratory's use of Liquid Argon and Nitrogen, with delivery expectations and flexibility for increased usage scenarios.
