GEM Calibrations

The Texas Commission on Environmental Quality (TCEQ) Office of Compliance and Enforcement is seeking annual calibration and preventative maintenance services for Landtec GEM 5000 and GEM 5000 Plus Portable Gas Analyzers across its sixteen regional offices. The procurement involves comprehensive instrument inspection and calibration for multiple gas measurements, including methane (0-100% volume), carbon dioxide (0-100% volume), oxygen (0-25% volume), carbon monoxide (0-2000 ppm), and hydrogen sulfide (0-1000 ppm). Key deliverables include a detailed calibration process adhering to ISO/IEC 17025 standards, manufacturer protocols, and equipment traceability, with each calibrated instrument requiring a unique, signed Statement of Calibration. The service must be completed within 21 days of receiving each analyzer, with potential component replacements such as sensors, transducers, pump, keypad, lens, tubing, USB cable, and battery. The solicitation was posted on September 17, 2025, with proposals due by October 1, 2025, and requires the successful vendor to provide monthly itemized invoices within 15 business days after work completion, including specific documentation and purchase order details.

While no specific set-aside designations are explicitly mentioned, the procurement requires vendors to meet numerous compliance certifications, including antitrust law compliance, child support verification, cybersecurity training, and intellectual property rights attestations. The contract involves return shipping to any of the 16 TCEQ regional offices or headquarters locations within Texas, with repair services to be charged at listed labor rates and parts billed according to special terms and conditions. An inspection fee may be charged for analyzers that cannot be calibrated or repaired. Although the exact budget range is not specified, the comprehensive nature of the calibration services and the potential for multiple instrument maintenance suggest a significant contract value. The TCEQ reserves the right to terminate contracts and audit vendor activities, emphasizing a rigorous selection process that prioritizes technical capability, compliance, and service quality.
