STATEMENT OF REQUIREMENTS

TITLE: Direct Combustion Mercury Analyzer

I. BACKGROUND INFORMATION

The Chemical Sciences Division (CSD) is involved in the development, renewal, and maintenance of reference materials and leading several quality assurance programs. This work involves the measurement of mercury in solid and liquid samples that include food, dietary supplements, coal, water, and environmental samples.

Measurement of mercury is of great interest to a wide variety of stakeholders due to its toxic effects. In order for

CSD to be able to meet the needs of customers and stakeholders, it is required that a current, reliable, high throughput, and state of the art direct combustion mercury analyzer be available within CSD.

II. SPECIFICATIONS

The Contractor shall provide one (1) analytical instrument system that meets the following minimum technical requirements.

System Requirements:

• Must be a benchtop direct combustion mercury analyzer that measures total mercury (Hg) through integrated sample drying, thermal decomposition, amalgamation, and atomic absorbance spectrometry.

• Must be capable of measuring total Hg in solid samples (fresh frozen, dried, or freeze-dried) and liquid samples containing up to 20 % acid.

• Must be able to analyze samples directly in weigh boats with no sample preparation or digestion required.

• Must include weigh boats for solid samples and liquid samples that are made of a material that can accommodate these diverse matrices and withstand up to 20 % acid without compromising the weigh boat integrity.

• Must have a weighing stand to hold sample boats on balance for capturing sample mass.

• Must have a lower working range limit less than or equal to 0.01 ng Hg and upper working range limit greater than or equal to 1500 ng Hg.

• Must have a method detection limit less than or equal to 0.001 ng Hg.

• Must have precision less than or equal to 1.5 % at 10 ng Hg.

• Must be able to auto blank to minimum Hg threshold set by operator when measuring high level Hg samples before moving to the next sample for measurement.

• Must have ability to pre-concentration of multiple low level Hg samples before releasing Hg from amalgamator for detection.

• Must have an integrated autosampler that can hold a minimum of 40 sample weigh boats.

• Must have autosampler that is enclosed or covered to protect samples.

• Must be able to analyze an individual sample in approximately 5 minutes.

• Must be able to use a carrier gas of high purity oxygen.

• Must have an exhaust outlet that can connect to an Hg trap or exhaust hose into fume snorkel.

• Must be able to utilize a 110v power supply.

• Must include an external laptop to control the instrument and connection cables.

• Must include spare consumables kit with catalyst tube and amalgamator.

• Must include a 4-place balance (0.1 mg readability; at least 220 g maximum capacity; full enclosure) with connection cables that can interface with the instrument to capture sample masses in instrument software.

• Must come with a minimum of a 1-year manufacturer warranty.

• Must include extended warranty for at least 2 years beyond the manufacturer warranty and the extended warranty includes annual preventative maintenance visits.

• The system must include an operations and maintenance manual covering proper operation, routine maintenance, and trouble shooting for the instrument and controlling software o The manual may be supplied in hard copy or electronic format (or both).

Software:

The direct combustion mercury analyzer software must be able to be installed on a laptop with a Windows operating system, have a library of broad application methods, and ability to download data as csv files or to

Microsoft Excel. Instrument software must display peak profiles, calibration information, raw data, statistics, and continuous instrument temperatures and voltage monitoring during operation. Software must autosave data as samples are measured.

Installation:

The Contractor shall install the instrument in Building Hollings Marine Laboratory, Room C203, at NIST

Charleston, SC. Installation shall include, at a minimum, uncrating/unpacking of all equipment, set-up and hook-up of all equipment, start-up, demonstration of specifications, and removal of all trash. . Installation will take place during normal business hours, between 7:30 am and 3:30 pm Eastern Time, Monday through Friday except Federal Holidays, and will be coordinated with the NIST Contracting Officer’s Representative (COR).

Installation is to occur within 10 days after receipt of direct combustion mercury analyzer.

Warranty:

The Contractor shall provide, at a minimum, a one-year warranty for the equipment. The warranty shall cover all parts, labor and travel. The warranty shall commence upon Government acceptance. The additional 2-year warranty shall cover the equipment for a total of three (3) years from Government acceptance.

Training:

The Contractor shall include training at NIST for up to four (4) NIST personnel covering normal operation, troubleshooting, and routine maintenance. Training will be provided during normal business hours, between

8:30am and 5:00pm Eastern Time, Monday through Friday, except Federal Holidays, and will be coordinated with the NIST COR to ensure maximum availability of NIST personnel. Training is to occur within 10 days of installation. The training may be completed on-site at NIST immediately after installation and demonstration of specifications.

III. PLACE OF PERFORMANCE

Manufacturing shall be completed at the Contractor’s facility. Installation of the instrument and training shall be accomplished at NIST, Charleston, SC. Normal duty hours are Monday through Friday, 7:30 a.m. to 3:30 p.m. with the exception of Federal holidays.
