FA860125Q0113 – WD XRF Instrument

Vendor Questions and Government Answers

1. Question: Are you exclusively considering Wavelength Dispersive XRF (WD-XRF) instruments, or would you also be open to Energy Dispersive XRF (ED-XRF) options?

Government Answer: We are exclusively considering WD-XRF instruments.

2. Question: The specified range of 0.5 to 3,000/30,000 ppm is quite broad. Do you anticipate that most measurements will fall within a narrower, more typical range?

Government Answer: No, a variety of products will be tested with this instrument with a wide variety of expected concentrations.

3. Question: 1. Can you confirm that the end user already has an XRF License for the state of Florida? Your office does have a valid XRF license, correct?

Government Answer: The end user already has an XRF license and XRF systems in use.

4. Question: In the past, the Aerospace Fuels Laboratory has ordered benchtop WDXRF systems, Supermini200 models. Is this what you need or a large system, such as the Primus IVi?

Government Answer: Vendors should quote the most cost effective system that meets all requirements of the Scope of Work.
