Requirements.docx

C.1 Requirement

The Contractor shall deliver, install, and provide training for one (1) Liquid Chromatograph equipped with a high-resolution mass spectrometer detector providing the capability to determine exact mass of ionic species that meets the Government’s minimum requirements as follows in Section C.2.

C.2 Salient Characteristics

C.2.1 Mass accuracy shall be to 4 parts per million (ppm) or better (e.g. lower number ppm is better), with both internal and external calibration methods.

C.2.2 The spectrometer shall be a high-resolution Fourier Transform bench-top system with a footprint no deeper than 34 inches, a width no more than 40 inches, and must be usable when positioned on a standard-height laboratory bench (30 inch base).

C.2.3 The spectrometer shall not require liquid cooling. The spectrometer shall not require a gas supply besides nitrogen (N2), no helium or argon required.

C.2.4 The maximum mass resolution shall be at least 120,000 and be obtainable at 200 (mass/charge) m/z based on full-width half-max peak treatment.

C.2.5 Dynamic detection range shall be >4000:1 for a spectrum acquired in a single transient/scan.

C.2.6 Scanned mass range shall comply with or exceed the following formula, expressed as the terminal limits of observed mass range as a function of the lower mass observed m/z ratio. The system shall observe an upper mass limit of at least 15 times the lowest mass observed (e.g. last mass = 15x first mass; e.g. scanning mass range = 1x-15x, where x = a mass fragment in m/z) in a single transient/scan.

C.2.7 Unit shall be capable of and include hardware for ElectroSpray Ionization (ESI) and Atmospheric Pressure Chemical Ionization (APCI).

C.2.8 A N2 generation unit shall be included if a N2 source is required for operation.

C.2.9 The Liquid Chromatography (LC) system shall include pumps & columns to accommodate both aqueous and reverse-phase use, with flow rates spanning 0.2 to 5.0+ (milliliter/minute) mL/minute.(broader range is better)

C.2.10 The LC system shall include autosampler capability with space for at least 12 samples.

C.2.11 The LC system shall include gradient pumps to enable the use of binary solvent systems.

C.2.12 The Contractor shall deliver the system to Aberdeen Proving Ground, MD 21005 within twelve (12) weeks after contract award for inspection and acceptance. The Contractor shall ensure the user acceptance by testing to demonstrate that the required functions are operating in the manner required for the ARL end users/customer base.

C.2.13 The system must be covered by a warranty of not less than one (1) year from the date of installation & certification at the Government site. The warranty shall cover all system components including accessories and vacuum pumps.

C.2.14 The Contractor shall include training on-site at the Government site no later than six (6) weeks after system installation. The Contractor shall provide a three (3) day training class to accommodate at least three (3) users. The Government will provide instructions detailing the specific date, time, and location of the training no later than one (1) week prior to the start of the training course. The Government may provide additional users based on available space and schedule for the training.
