The Department of Agriculture (ARS) has the need for the following products:

001) Portable Photosynthesis System

Scope of Work:

The USDA-ARS Agroecosystems Management Research Unit (AMRU) of the National Laboratory for Agriculture and the Environment (NLAE) in Ames, IA is requesting quotes for a portable photosynthesis system capable of rapidly quantifying leaf-scale photosynthesis and gas exchange in field, greenhouse, and laboratory conditions.


This instrument will assist our unit with the requirement to fulfill ongoing research obligations under National Program 216 Sustainable and Resilient Cropping Systems for Midwestern Landscapes (5030-12210-003-00D). This instrument will provide rapid, scientifically robust data pertaining to leaf-scale gas exchange in a variety of cropping systems. This data will inform research goals pertaining to crop growth and development, as well as system-wide nutrient balances and environmental quality.

Technical Requirements:

  • The instrument must be capable of measuring simultaneously measuring absolute CO2 and H2O in leaf gas samples with the following sensitivity:

    • CO2: up to 3000 ppm with a sensitivity of ±1 ppm

    • H2O: up to 75 mb with a sensitivity of ±1.5%

  • The instrument must be operational under ambient lighting and have the capacity to control photosynthetically active radiation (PAR) levels up to 3000 µmol m-2 s-1 with a sensitivity of ±5%.

  • Leaf chambers must be up to 9 cm2, with the potential for using apertures to make the sample area adjustable

  • The instrument must be able to maintain customized leaf temperature, CO2, H2O, and PAR levels during measurement periods:

    • Leaf temperature: ±0.5 C

    • CO2: ≤±1 µmol mol-1 variation at 400 µmol mol-1 from any orientation

    • H2O: ≤±1 µmol mol-1 variation at 400 µmol mol-1

    • PAR:

  • The instrument must be portable and easily moved by one individual

  • The instrument must come with accompanying software to transfer data from the instrument to commonly used formats (e.g., .csv, .xlsx)

  • The instrument should be equipped to rapidly (
  • The leaf chambers must be equipped with a light source capable of measuring chlorophyll a fluorescence simultaneously with leaf gas exchange

Note: Quoted products should be USA Manufactured if at all possible.

Government Furnished:

Contractor will not require access to government facilities as related to this purchase.

Evaluation Factors:

Lowest price, technically acceptable. The government intends to award a firm-fixed price award based on the lowest price technically acceptable quote. The lowest priced quote will be evaluated first; if not found acceptable, the next lowest priced quote will be evaluated, and so on until an acceptable quote is identified. The government will not review higher priced quotes if the lowest priced quote is determined to be technically acceptable. For a vendor’s quoted products to be considered technically acceptable, they must meet all of the technical requirements identified in the solicitation/SOW.

Key Deliverables:

  • Portable Photosynthesis System.

  • 1-year Manufacturer Warranty

  • Training for Instrument Operators.

  • Emergency Services
