About this file
This combined synopsis and solicitation requests quotes for the purchase of handheld X-ray fluorescence analyzers to meet the technical requirements outlined in Attachments 1 and 2. The Consumer Product Safety Commission seeks to procure twelve analyzers under CLIN 0001 and up to four additional units under CLIN 0002. Optional on-site training valued at up to sixteen sessions is also requested under CLIN 0003. Quotes are due by August 10, 2021 and will be evaluated based on the ability to meet all mandatory technical requirements with consideration given to price and delivery terms. Live demonstrations of the analyzers functional capabilities will take place the week of August 2-6, 2021 according to the evaluation criteria defined in Attachment 2 which includes analyzing standard reference materials within specified tolerance ranges and automatically identifying sample matrices in test all mode. Award will be made to the responsible offeror providing conforming handheld XRF units at the lowest price.

Technical Evaluation: Handheld X-ray Fluorescence
(XRF) Analyzer
The XRF analyzer will be evaluated and performance validated based on a live demonstration of factors A and B Factor C will be evaluated by preparing the technical specifications of the quoted handheld XRFs to the requirements listed in the Statement of
Work.
This is a lowest priced technically acceptable award. All technical and performance requirements are mandatory and must be met in order to be eligible for award.
FACTOR A: The XRF will be evaluated based on measurement results obtained using the following reference standard materials:
Subfactor 1: ERM®-EC681k Polyethylene (high level)
Subfactor 2: ERM®-EC680k Polyethylene (low level)
Subfactor 3: NIST Standard Reference Material® 2861 PVC
Subfactor 4: Restriction of Hazardous Substances (RoHS) 2-3 Glass Standard
Subfactor 5: NIST Standard Reference Material® 2569 Level 3 Lead Paint Films
Measurement results shall be within the following low/high limit specifications outlined in the tables below for each of the reference standard materials:
Subfactor 1: ERM®-EC681k Polyethylene (high level) Standard
ERM®-EC681k
Element Certified Value (ppm or mg/kg)
Low Limit (ppm or mg/kg)
High Limit (ppm or mg/kg)
Lead (Pb) 98 74 122
Arsenic (As) 29 15 44
Cadmium (Cd) 137 96 178
Chromium (Cr) 100 50 150
Measurement time will be a minimum of 60 seconds on optimum filter setting configuration for each element
Subfactor 2: ERM®-EC680k Polyethylene (low level) Standard
ERM®-EC680k
Element Certified Value (ppm or mg/kg)
Low Limit (ppm or mg/kg)
High Limit (ppm or mg/kg)
Lead (Pb) 13.6 6 20 configuration for each element
Subfactor 3: NIST Standard Reference Material® 2861 PVC
NIST Standard Reference Material® 2861
Element Certified Value (ppm or mg/kg)
Low Limit (ppm or mg/kg)
High Limit (ppm or mg/kg)
Lead (Pb) 88.3 70 106 configuration
Subfactor 4: RoHS 2-3 Glass Standard
RoHS 2-3 Glass Standard
Element Certified Value (ppm or mg/kg)
Low Limit (ppm or mg/kg)
High Limit (ppm or mg/kg)
Lead (Pb) 1000 Must have a detectable measurement reading >100ppm.
configuration
Subfactor 5: NIST Standard Reference Material® 2569 Level 3 Lead Paint Films
NIST Standard Reference Material® 2569 Level 3 Lead Paint Films
Element Certified Value (ppm or mg/kg)
Low Limit (ppm or mg/kg)
High Limit (ppm or mg/kg)
Lead (Pb) 314 Must have a detectable measurement reading.
Measurement time will be 120 seconds on optimum filter setting configuration
FACTOR B: Evaluate the use of the “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.
The following reference standards will be used to evaluate:
Subfactor 1: ERM®-EC681k Polyethylene (high level)
Subfactor 2: NIST Standard Reference Material® 2861 PVC
Subfactor 3: MBH Analytical Tin Check Sample (180-606)
Subfactor 4: XOS Coated Reference Sample 900071-08 ZINC
The “test all” mode (or equivalent) will correctly identify the sample matrix and shall provide measurement results within the following low/high limit specifications outlined in the tables below for each of the reference standard materials:
Subfactor 1: ERM®-EC681k Polyethylene (high level) Standard
