Submersible Fluorometer System   3

Submersible Fluorometer System (Turner Designs Model C6P)
The U.S. Geological Survey (USGS) is issuing this request for information (RFI) as a means of conducting market research to determine the availability of potential contractors who can provide a Turner Designs Model C6P Submersible Fluorometer. The project currently has two Turner C6Ps for the development of models for mercury proxies. The project will be expanding the modeling effort and requires another Turner C6P with the same configuration as the ones currently deployed to maintain model consistency and data quality objectives.
The C6P configuration is as follows:
turbidity (850 nm LED; range 1 -1,500 ntu)
chlorophyll (excitation 450-460nm, emission 674-718; range 0.3 200 g/L)
chlorophyll (excitation 625-635, emission > 695nm; range 0.3 200 g/L)
optical brighteners (custom configuration (excitation 360-370, emission 415-440 nm); range 0-30 ppb
fluorescein (excitation 45-470, emission 530-560 nm; range 0.1 - 100 ppb)
Tryptophan/wastewater (excitation 270-280, emission 322-378 nm; range 0.3 200 g/L)
The device must be robust for long-term field deployment with minimum maintenance and be telemetry capable. The optical brightener sensor needs to be customized to meet USGS requirements to match previously purchased C6Ps for consistency within and across USGS projects.
This request for information is issued for the sole purpose of conducting market research in accordance with the Federal Acquisition Regulation (FAR) Part 10.
