This document is Attachment A, a specifications sheet for Millipore Mitex Membrane Filters for the Texas Commission on Environmental Quality (TCEQ), issued under Solicitation Number 582-25-08668. The procurement is driven by the US Environmental Protection Agency's (USEPA) requirement for the TCEQ Monitoring Division to collect air monitoring data under 40 Code of Federal Regulations Part 58. The specification details the purchase of membrane filters to be used at existing air monitoring stations, with specific requirements for a Mitex Membrane Filter that is hydrophobic, 47 mm in diameter, with a 5.0 µm pore size, 170 µm thickness, and packaged in quantities of 100 filters.

The specifications are highly precise, calling for Millipore Part # LSWP04700 or an equivalent filter with a plain filter surface made of Polytetrafluoroethylene (PTFE). While no specific pricing, budget, or funding details are provided in this attachment, the document represents a targeted procurement to support the agency's air quality monitoring infrastructure. The technical specifications suggest a specialized scientific requirement that ensures consistent and reliable air monitoring capabilities across the TCEQ's monitoring stations.
