The Science Acquisition Team for USGS Programs, Reston Science Acquisition Branch is conducting market research to identify sources capable of providing simultaneous measurement of stable isotope ratios from biogenic carbonate materials for one base year and four one-year option periods USGS, St. Petersburg Science Center requires a laboratory that can perform simultaneous measurement of δ18O, δ13C, and δ15N in samples of powdered CaCO3 from biogenic materials such as coral skeletons, mollusk shells, and crustacean shells. These measurements should be made using an IRMS with dual-inlet and continuous-flow inlets coupled to a Gas-Bench II prep device for headspace analysis of evolved CO2 δ18O, δ13C, or an IRMS w/ continuous-flow inlet coupled to a Thermo Flash EA - ConFlo IV for gas analysis of combusted samples (δ13C, δ15N).

Specifications:

-Working sample preparation laboratory with adequate bench-top space and facilities to prepare and process CaCO3 samples. Required equipment includes: microbalance; appropriate spatulas and brushes for transferring carbonate samples.

-Working SIR-MS laboratory capable of measuring CaCO3 samples for δ18O, δ13C, and δ15N. Required equipment includes: Thermo Scientific Delta-series SIR-MS with Gas-Bench II prep device for analysis of CO2 gas (δ18O, δ13C) from CaCO3 prepared in 12 mL and 4.5 mL Exetainer analysis vials; Thermo Flash EA - ConFlo IV for gas analysis of combusted samples (δ13C, δ15N); software, peripherals, and interface to operate SIR-MS using a desktop computer; setup required to react CaCO3 samples with 100% H3PO4.

Responses: All interested parties should notify this office via e-mail by posted date. Responses shall include:

(I)To what extent each of the specifications can be met.

(II) Include your type of business (i.e. commercial, academia), whether your organization is classified as a large or small business. If a small business, you must also list any small disadvantaged status you hold [HUBZone, 8(a), Service Disabled Veteran Owned Small Business (SDVOSB), Women Owned Small Business (WOSB), Economically Disadvantaged Women-Owned Small Business (EDWOSB), etc.].

(III)Experience/ performance through the description of completed projects. If an authorized distributor/reseller provide relevant documentation.

Your company must have a UEI number and be registered on-line at the System for Award Management (SAM). You will also be required to provide your small business status information either via the Online Representations and Certifications also located at the SAM.gov website before an award to your company can be made. Your on-line registration will cover any/all of your offers to the Federal Government and only needs updated annually.

Responses to this source sought notice will be used by the Government to make appropriate acquisition decisions. All interested sources must respond to future solicitation announcements separately from responses to this market survey. Any solicitation that may be issued will be posted on the SAM.Gov. It is the responsibility of potential responders to monitor the site for additional information pertaining to this announcement.
