Isotopic Water Analyzer

This combined synopsis/solicitation for commercial items prepared in accordance with the format at FAR Subpart 12.6, as supplemented with additional information included in this notice.  This announcement constitutes the only solicitation; quotes are being requested and a written solicitation will not be issued.

The solicitation number W913E521Q0004 is being issued as a request for quotation (RFQ).

The associated North American Industry Classification System (NAICS) code is 334516 – Analytical Laboratory Instrument Manufacturing.

The U.S. Army Engineer Research and Development Center (ERDC), Cold Regions Research and Engineering Laboratory (CRREL) has a requirement for an Isotopic Water and Vapor Analyzer with the following specifications:

Requirement

Details

Isotope Water Analyzer

Analyzer able to measure of 18O, D, 17O and 17O-excess in water or water vapor

Water Vaporizer

Required system component

Autosampler

Required system component

Monitor

Required system component

Onsite installation and training; One Day

Required system component

Desiccant Drier Kit

Required system component

Salt Liner Package

Required system component (to enable isotope analyses of high saline concentrations up to 20% concentration)

Pump

Required system component

Dry Gas “Zero Air” Kit

Required system component.  This is defined as a gas plumbing and regulator kit that connects the isotope analyzer system to tanks containing compressed dry air or “Zero Air”.

Field Portable Analyzer (weight less than 50lbs, volume less than 2200 cubic inches)

Field Portable is defined as a system that can easily be carried into the field by a scientist for use in remote camps or boats for field analyses;  specifically a field portable analyzer must weigh less than 50lbs and occupy less than 2200 cubic inches (i.e., the approximate size of a desktop computer) while meeting all the measurement precision and sensitivity standards of the DOR.  Peripheral accessories (monitor, pump, tray) are generally minor so are not included in the above weight/volume limits.

Saline water sample concentrations

Isotope Analyzer must be able to measure accurately in saline water sample concentrations up to 20%

Independent Operation

Independent Operation means that the system does not require a separate computer for operation

Export Data File as .csv Format

Analyzer data files may be recorded in .csv compatible format for export

Analysis of matrix bound water in solid samples (OPTION)

The analyzer shall have the optionality to expand via add-on peripherals to allow analysis of matrix-bound water in solid samples (e.g., soils, leaf matter, wood matter)

Maximum 24-hour Drift (vapor and liquid)

δ18O = 0.2‰

δ17O = 0.2‰

δD = 0.8‰

δ18O = 0.025‰

δ17O = 0.025‰

δD = 0.1‰

17O-excess = 0.015‰
