About this file
This document is a Statement of Need that describes the requirement for a Dual Inlet system and accessories to be integrated with an existing Delta V Plus Isotope Ratio Mass Spectrometer (IRMS) at the Geology, Energy and Minerals Stable Isotope Lab (GEMSIL). The Dual Inlet system will allow for higher precision measurement of isotope ratios of gases compared to the current continuous flow capabilities. This upgraded capability is needed to support the Mineral Resources Program's research on the origins and transformations of critical minerals and tracing environmental impacts related to mining activities.
The related federal contract opportunity is a Request for Quote (RFQ #140G0124Q00258) issued by the Department of the Interior US Geological Survey Office of Acquisitions and Grants.

PR # [Insert PR Number] Statement of Need
Description Of Need:
The stable isotope measurement of gaseous, dissolved, and solid materials provides information about the sources, transfer, and processes that affect chemical elements at the Earth surface. In many cases, the information provided by isotopic measurements cannot be acquired through other means. Therefore, stable isotope measurement capabilities provide unique insights into such Mineral Resources Program (MRP) interests such as the origin and transformation of critical minerals and their chemical constituents and the tracing of environmental impacts related to mining activities. The requested Dual Inlet system, with associated differential pump and spare parts, is an upgrade to the Delta V Plus Isotope Ratio Mass Spectrometer (IRMS) (Serial number 08529D, Property number G9001734) that is in use in the Geology, Energy and Minerals Stable Isotope Lab (GEMSIL). Currently, the GEMSIL Delta V Plus can only be operated in continuous flow mode. In contrast, the Dual Inlet upgrade allows for the measurement of isotope ratios of gases at higher precision than is possible with continuous flow techniques. For example, this higher precision would permit the comparison of the multiple stable isotopes (i.e., 16O, 17O, 18O) of gaseous oxygen (O2) from natural samples and experiments at the higher precision required (within the second decimal of per mille of Δ17O) to resolve triple oxygen isotope variations that commonly occur within the first decimal of per mille of Δ17O. In turn, such measurements can be used to track O2-consuming processes during abiotic and biological mineral weathering reaction experiments such as being undertaken as part of the MRP-funded Sulfur Cycle project.
Specifications/Salient Characteristics:
· Sample and reference gas inlets (hence, Dual Inlet) for the Delta V Plus IRMS
· Sample and reference gas bellows that allow precise control and balancing of the pressure of sample and reference gases, and thus the identical treatment of sample and reference materials that is a fundamental principal of isotope ratio mass spectrometry
· Differential pump (turbo pump) needed for the Dual Inlet capability
· Spare parts kit required for repairs and maintenance of the Dual Inlet system
· Dual Inlet system is fully compatible with the existing Delta V Plus isotope ratio mass spectrometer in the GEMSIL lab
· Installation of the Dual Inlet system on to the existing Delta V Plus IRMS located in the GEMSIL lab
