About this file
This is a Specifications attachment for a Request for Quotation (RFQ) solicitation numbered 1232SA26Q1230-B issued by the Department of Agriculture Agricultural Research Service for procurement of a single quadrupole gas chromatograph-mass spectrometer. The specification details a sophisticated analytical instrument with electron ionization and chemical ionization capabilities, supporting full-scan and selected ion monitoring modes. Key technical requirements include a mass range of 1.2 to 1,100 atomic mass units with quadrupole scanning at 16,000 units/second minimum, acquisition rates exceeding 200 scans/second during SIM and 60 scans/second during full-scan operations, and a detector with a minimum linear range of 0 to 100 microamps. The instrument must feature an integrated three-axis autosampler capable of handling liquid injection, headspace, and SPME sample processing with compatibility for various vial plate formats (4608-well plates, 840-place vials, 648-place 2mL vials, and 240-place 10-20mL vials), along with an automated SPME arrow expansion kit and headspace tool configured for a 2.5mL syringe with 65mm needle.
The equipment shall be delivered within 60 days after receipt of order to Lab 02 at Harbor Branch Oceanographic Institute, 5600 US Route 1, Fort Pierce, Florida 34946. The acquisition is designated as a Total Small Business Set-Aside with a NAICS code of 334516 and small business size standard of 1,000 employees. Quotations are due September 22, 2026 at 9:00 AM Pacific Time and must include firm fixed pricing valid for at least 30 days, place of manufacture for all items, SF-1449 form completion, SAM.gov UEI, and a capability statement with technical documentation demonstrating compliance with all specifications. Prospective quoters must submit all required documentation or face automatic rejection of their quotation without further consideration.

SPECIFICATIONS
1.0 Specifications Description:
Single quad gas chromatograph – mass spectrometer Single quadrupole Capacity for electron ionization, chemical ionization, with full-scan (FS), selected ion monitoring (SIM) and simultaneous FS/SIM within sample injection. Has capacity for vacuum region of the mass spectrometer to be isolated from the column to enable the gas chromatograph columns to be quickly changed with no venting necessary. Compatible with capillary columns within a range of 0.32 – 0.1 mm (internal diameter) with split/splitless injector module. Equipment should come with data system software using common platform for gas chromatograph – mass spectrometer quantification. Software should include commercial mass spectral library. Should have headspace syringe tool for a 2.5 mL syringe to accommodate a needle length of 65 mm.
Detector: minimum linear range of 0 – 100 microamps (μA) Ion source types: programmable to 350°C Acquisition rate: during SIM, more than 200 scans/second. During FS, more than 60 scans/second Pumping: more than 250 liters/second, minimum mechanical rotary vane of 3 m3/hour oil pump, minimum turbomolecular pump capacity of 60 liters/second Mass range: minimum of 1.2 – 1,100 u with unit mass resolution Mass filter and mass analyzer: needs to have some protection in place to minimize quadrupole from burning and for noise reduction. Minimum quadrupole scanning of 16,000 units/second.
Carrier gas: should be able to be operated with either helium or hydrogen.
Gas capabilities: digital flow control on a sample-by-sample basis. Gases include ammonia, methane, isobutane or mixtures of these with carbon dioxide presets. Capacity for pulsed positive ion negative ion chemical ionization to allow for switching on a scan-to-scan basis between positive and negative ionization mode.
Electrical: can be adjustable up to 150 electronvolts depending on the ion source. Has a maximum of 125 volts.
Emission current: up to 350 μA Transfer line temperature: up to 400°C Mass resolution and stability: has capacity for automatic tuning down to 0.4 units as well as manual tuning. Better than 0.1 units/48 hours/delta temperature.
Auto sampler: Integrated 3 axis autosampler capable of advanced sample handling and ability to integrate liquid injection, headspace, and SPME (Solid Phase Micro Extraction) and SPME arrow sample processing and injection. Capable of automatic and unattended injection tool changes. Selectable from 0.1uL/s to 2000 uL/s injection speed and 0.1 to 10,000 uL injection volume. With washing station and 3 trays for 2 mL vials. Compatible with trays to accommodate 4608 well plates, 840 place 0.5 or 0.7 mL vials, 648 place 2 mL vials, and 240 place 10 mL or 20 mL vials.
SPME arrow kit: Automated SPME and SPME arrow expansion kit compatible with the Auto sampler for automation of all SPME and SPME arrow sample preparation steps (i.e., Fiber preconditioning, adsorption, desorption and fiber washes). Includes tray to hold 20 mL vials.
Headspace Tool: Headspace tool compatible with the autosampler to accommodate a 2.5 mL syringe with a 65 mm needle length.
