Two high frequency, field-deployable and low power CO2/N2O analyzers

Tender description

The requirements call for two high precision, high frequency field-portable and low power CO2/N2O analyzers to operate in field environments including in remote tropical environments. A single tender action is requested for the following key reasons: •N2O Sensitivity: The instrument must be able to resolve N2O at the parts per trillion level. This requires that the instrument operates in the mid infrared (Mid IR) spectral range. MID IR based instruments such as the Aeris MIRA ULTRA have orders of magnitude greater sensitivity for N2O than alternative technologies utilised by all competing manufacturers. •Field portability: The analyser must be weather resistant, capable of operating in humid environments (>90% humidity) and weigh no more than 6 kg as analyzers will be routinely carried to and operated around remote field sites. •12 hr+ run time: No alternative analyser can satisfy the low power requirement and thus long run time required. The Aeris MIRA Ultra has the added advantage that any portable external battery can be used to power the instrument allowing for long run times (up to 24 hours using commercially available portable battery banks) without the need for additional, expensive proprietary batteries. •Lead time: This purchase is funded by a UKCEH capital award and must be receipted before the end of 2022.
