## Summary

The National Physical Laboratory, a public body governed by law, has awarded a contract for the purchase of a G2401 Gas Concentration Analyzer to Amiston Limited. The procurement process was conducted as a limited procedure without prior publication of a call for competition. The contract, valued at £130,000, was signed on 24th January 2023. The equipment is intended for precise measurement of carbon monoxide, carbon dioxide, methane, and water concentrations, meeting international atmospheric monitoring requirements.

This tender for the G2401 Gas Concentration Analyzer presents business opportunities for suppliers in the laboratory and precision equipment sector. Businesses with expertise in providing analytical instruments for atmospheric science, air quality monitoring, and emissions quantification would be well-suited to compete in this procurement process. The National Physical Laboratory's procurement decision was based on technical reasons, as Picarro was deemed the only vendor capable of meeting the required specifications for the equipment.

## Notice

The Picarro G2401 gas concentration analyzer provides simultaneous, precise measurement of carbon monoxide (CO), carbon dioxide (CO2), methane (CH4) at parts-per-billion (ppb), and water (H2O).

### Lot Information

Lot 1

The Picarro G2401 gas concentration analyzer provides simultaneous, precise measurement of carbon monoxide (CO), carbon dioxide (CO2), methane (CH4) at parts-per-billion (ppb), and water (H2O) vapor at parts-per-million (ppm) sensitivity with negligible drift for atmospheric science, air quality, and emissions quantification. It meets the World Meteorological Organization (WMO) and Integrated Carbon Observation System (ICOS) performance requirements for CO, CO2, and CH4 atmospheric monitoring. Simultaneous and continuous measurement of four atmospheric trace gases Parts-per-billion sensitivity, precision, and accuracy with exceptionally low drift Compliant with WMO and ICOS international ambient atmospheric monitoring requirements Water correction automatically reports dry gas mole fractions Precision at 5 seconds, 5 minutes, and 60 minutes is 15, 1.5, and 1 ppb for CO; 50, 20, and 10 ppb for CO2; and 1, 0.5, and 0.3 ppb for CH4. Maximum drift at standard temperature and pressure (STP) over 24 hours is 10 ppb for CO; 100 ppb for CO2; and 1 ppb for CH4. Water correction software automatically reports dry gas mole fractions to help reduce research complexity and consumable costs.

### Procurement Information

Competition is absent for technical reasons: Picarro is the only vendor that can provide this equipment to the required specification.
