STATEMENT OF WORK

Title: Quadrupole Mass Spectrometer

NB646050-25-02231

I. BACKGROUND INFORMATION

The Chemical Sciences Division is currently developing instrumentation, measurement techniques, and technical reference materials in support of Direct Air Capture (DAC) studies within the NIST Carbon Capture Program (CCP). To enhance NIST’s capability in studying the impacts of long-term simulated aging via temperature cycling and the characterization of candidate sorbent materials, the acquisition of a quadrupole mass spectrometer is required.

The acquisition of a mobile general-purpose quadrupole mass spectrometer will permit two distinct measurements: the identities and concentrations of materials evolving from sorbent materials subjected to a temperature-cycling in simulated aging experiments and reaction products from gas solid reactions in situ with simultaneous infrared spectroscopy to study both solid-phase composition variations and the identities and concentration-time profiles of gas-solid reactions, including adsorption processes. In this way, candidate materials for DAC can be evaluated and studied under conditions more consistent with those found in actual use.

II. SPECIFIC REQUIREMENTS

The contractor shall provide a mobile, general-purpose quadrupole mass spectrometer. The spectrometer must meet following minimum specifications:

1. System shall be capable of measuring samples with an inlet pressure ranging from 300 hPa to 1200 hPa, absolute.

2. System shall provide a heated transfer line (at least 70ºC) at least 50 cm in length; a variable temperature from room-temperature to 150 ºC or higher is preferred but not required.

3. System shall be capable of measuring a mass range up to 200 atomic mass units (amu).

4. System shall have a detection limit of 10 parts per billion or lower by volume (10 nmol/mol).

5. System shall have a response time to changes in inlet concentrations of 400 ms or lower.

6. System shall utilize a turbomolecular pump for high-vacuum and include a oil-free backing pump, such as a scroll pump.

7. System shall utilize variable-energy electron impact ionization for ionizing the inlet analyte;

ionization energies must be selectable with a minimum of 20 electron-volts (eV) and a maximum of 80 eV.

8. System must have a variable dynamic range and must be able to change this dynamic range during a single scan or when scanning multiple mass-to-charge ratio regions.

9. A cart with casters shall be provided that will house the instrument and any necessary auxiliary pumps, including the turbomolecular pump backing pump in a single unit that can be readily moved from area to area in a normal laboratory setting.

10. System must have a means to synchronize the mass spectral acquisition with an external trigger, for example via a 5 V or 10 V pulse.

11. System shall include a control computer with monitor or laptop for controlling the instrument and collecting the data.

12. Control software shall provide the following capability: selection of a single-ion or narrow range (< 2 amu) for monitoring; scanning over the entire range of available mass-to-charge ratios;

recording a single-ion or a narrow range over time – maximum time must be at least 4 hours.

Note that the dynamic range (see #8 above) must be selectable in software. Quadrupole parameters must be selectable in software.

13. Software shall include a version of the NIST mass spectrometric database not exceeding 2 years prior to the date of award; control software must provide an interface between the measured spectra and the database.

14. Electrical requirements must be U. S. standard 60 Hz, 110V and not exceed 20A with a U. S.

style plug.

15. Warranty: The Contractor shall provide, at a minimum, a one-year warranty for the equipment.

The warranty shall cover all parts and labor. The warranty shall commence upon successful delivery.

All work shall be completed at the Contractor’s facility. Installation of the instrument shall be accomplished by the Subject Matter Expert at NIST, Gaithersburg, Maryland. Normal duty hours are Monday through Friday, 8:30 a.m. to 5:00 p.m. with the exception of Federal holidays.

III. GENERAL REQUIREMENTS

Inspection & Acceptance In addition to the inspection and acceptance terms articulated in the specific FAR clause, the Government reserves the right to perform such performance tests and evaluations as defined below to verify specified system performance. Such tests and evaluations, if performed, shall be conducted within the environment that the system is to be operated. The Contractor has the right to be present during the tests and evaluations, if performed, at the Contractor’s expense.

NIST may choose at its discretion to forego this part of acceptance testing.

A visual inspection of the equipment will be performed by the NIST POC to identify surface defects or any form of indication that any equipment was damaged during transport to NIST. The Government shall have sole discretion to require repair or replacement of damaged and/or nonconforming supplies at no cost to the Government. The Government at any time prior to acceptance shall reject the equipment due to defects and/or nonconformance. The vendor is responsible for latent defects discovered any time during the warranty period. However, the extent of its liability shall be prorated over the useful life of the equipment.

Ownership of the equipment shall transfer to NIST upon acceptance by the Government.

The Government will test, inspect, and accept or reject the equipment within seven (7) business days of the receipt of the equipment unless otherwise indicated above. The Government reserves the right to conduct quality assurance testing to confirm that a given instrument(s) meets the manufacturer’s and/or the Government’s performance specifications. It is anticipated that the equipment will meet all manufacturer’s specifications and/or the Government’s performance specifications identified in the most recent operations and maintenance manual for each piece of equipment and/or in this document.
