Consumer Product Safety Commission Statement of Requirements

Handheld X-ray Fluorescence (XRF) Analyzer

SECTION I: Description of Requirements

The Consumer Product Safety Commission (CPSC) intends to award a contract for portable Handheld X-ray Fluorescence (XRF) Spectrometers. The XRF analyzers must be capable of measuring lead (Pb) content in children’s products to determine compliance with the Consumer Product Safety Improvement Act (CPSIA). The XRF must meet the requirements outlined for the testing apparatus in the ASTM F2617 Standard Test Method for Identification and Quantification of Chromium, Bromine, Cadmium, Mercury, and Lead in Polymeric Material Using Energy Dispersive X-ray Spectrometry. Units must be suitable for use as a handheld analyzer for the measurement of lead, cadmium, arsenic, antimony, selenium, barium, chromium, and mercury in consumer products including metals, plastic, glass, and paint. The XRF must be capable of effectively measuring elements with atomic number at least as low as phosphorus (P) without the use of vacuum or helium purge.

SECTION II: Contract Type

This will be a firm-fixed-price (FFP) contract.

SECTION III: Background

The CPSC laboratory, field, and import surveillance staff require XRF analyzers that are critically needed to screen consumer products for lead (Pb) and other elements of interest.

SECTION IV: Technical Requirements and Performance

The XRF analyzer must be new and a model currently in production. Refurbished or demonstrator instruments are not acceptable. The XRF analyzer will be robust and durable for daily use in both a laboratory and field setting and must be suitable for continuous local and/or long-distance transport.

The XRF analyzer system must meet or exceed the following functions and specifications:

A. Instrument must operate with a 50 kV X-ray tube and shall not employ a radioactive isotope source. X-ray detector with energy resolution equal to or better than 185 eV full width at half maximum of the Mn Kα line.

B. Instrument must contain a Silicon Drift Detector (SDD) capable of effectively measuring elements with atomic number at least as low as phosphorus (P) without the use of vacuum or helium purge. Should have the ability to process over 180,000 detector events per second.

C. Instrument will include a built-in camera to provide close up view of analysis area.

D. Instrument must be able to achieve a minimum 3mm small spot size with the capability of a larger spot size for sample data acquisition. The software must allow the user to easily switch (toggle) from the small spot (3mm) to the larger spot as needed.

E. Instrument must include a minimum of two (2) Li-ion batteries, each capable of powering the XRF analyzer at least 4 hrs. without external power and include a battery charger and accessories needed to recharge batteries; AC adapter.

F. Instrument will include a clip-on backscatter shield. No portable fully shielded test stand is desired for this acquisition.

G. Instrument will include preprogrammed software modes that will accurately quantitate lead and other elements in a variety of homogeneous matrices such as metal, plastic, and glass and a mode for user-definable calibrations and analyses. The analyzer must include modes for quantitative determination of concentrations in percent (%) and parts per million (ppm) of target elements in plastic, metal, and glass.

H. The preprogrammed software modes must include a specific “test all” mode or equivalent for sample analysis. The “test all” mode or equivalent will automatically select the mode for the user when the user is uncertain of the appropriate mode to choose. The “test all” mode or equivalent will determine the sample matrix (i.e.

metal, plastic, painted metal, PVC plastic) and apply the appropriate algorithms for elemental detection and quantification.

I. Instrument must be capable of detecting Pb, Sb, As, Ba, Cd, Cr, Hg, Se, Br, Cl in paint layers on painted consumer products. The analyzer must be able to detect < 80 parts per million (ppm) Pb on 20-micron thick paint layer. The analyzer must be able to detect and measure Pb on mass per unit area basis using the National Institute and Standards Technology (NIST) Standard Reference Material® 2569 Level 2 and Level 3 Lead Paint Films.

J. Instrument must be capable of quantifying and detecting Pb, Sb, As, Ba, Cd, Cr, Hg, Se, Br, Cl in metal, plastic, glass, rubber, textiles. The analyzer must be able to detect < 20 ppm Pb in plastics. The analyzer must be able to detect and accurately measure Pb on mass fraction basis in plastic certified reference materials that contain low and high levels of Pb such as the European Reference Material ERM®-EC680k, ERM®- EC681k and the NIST Standard Reference Material® 2861 PVC plastic. The analyzer must be able to detect < 70 ppm Pb in metal alloys such as zinc, tin, copper, steel.

K. Instrument must be able to detect and accurately measure Pb on mass fraction basis in glass certified reference materials that contain high levels of Pb such as the Restriction of Hazardous Substances (RoHS) 2-3 Glass Standard.

L. The instrument display must include a touch screen display which allows user input and reading of results (within seconds) at the point of use. The analyzer shall contain user-friendly, graphical interface software compatible with Microsoft Windows 10 or later. For data handling, the analyzer must include means for assigning sample numbers to test data, store, transfer, and retrieve reports and sample numbers securely including transfer of data to Windows PC.

M. Instrument must operate with a stand-alone laptop computer and include a PC connection cable. Laptop computer is not included in acquisition.

N. Instrument must include calibration check standards (a minimum of one metal alloy standard and one plastic standard material) for calibration check.

O. Instrument must have password protection capabilities in the software for added security for appropriate personnel use.

P. Instrument must include a carrying case to safely transport XRF analyzer.

Q. Maximum weight of analyzer with battery will not exceed 4 lbs.

SECTION V: Requirements

The contractor will provide the following:

A. Technical documentation:

• The contractor must provide a Certificate of Calibration with each analyzer purchased. The Certificate of Calibration shall contain all the measurement readings of reference materials the vendor used for calibration verification.

• The contractor shall provide a radiation safety certificate with the instrument stating that the instrument meets all federal and state radiation safety requirements.

• The contractor must provide a User Manual with the analyzer.

B. Maintenance:

• On or after the expiration of the warranty period and should it become necessary, the contractor will provide a quote within one week of request for the cost of repair and/or calibration of the XRF analyzer. In addition, a loaner XRF analyzer from the contractor must be made available to CPSC free of charge during any repair incident and shall be the similar make/model of the CPSC XRF analyzer being repaired.

• The vendor must be able to provide local service support.

C. Training: Upon request from the Contracting Officer Representative (COR), the contractor will provide a minimum ½ day on-site training that includes: operation of unit, routine maintenance, basic application, and safety. On-site training may require a maximum of sixteen (16) separate locations throughout the continental United States.

D. Warranty: The contractor will provide a minimum two (2) year warranty for the instrument that covers all parts, labor, and travel.

SECTION VI: Technical Evaluation

The contractor will provide the CPSC with a live demonstration to validate the performance of the XRF analyzer based on the Technical Evaluation Factors (Attachment 2). The demonstration will take place at the CPSC’s National Product Testing and Evaluation Center (NPTEC) located at 5 Research Place (5RP) in Rockville, MD. The performance requirements are mandatory and must be met in order to be determined eligible for award.
