About this file
The file is a Question and Answer (Q&A) Log related to a Request for Information (RFI) for an XRD Diffractometer System issued by the U.S. Department of Labor's Occupational Safety and Health Administration (OSHA). The Q&A log contains two specific questions and responses regarding sample holder requirements for the diffractometer system, with clarification that the sample holders must accommodate 25 mm diameter silver membrane filters used for crystalline silica sample deposition.
The RFI was released with a question submission deadline of December 17, 2025, and responses are due on January 07, 2026 at 2:00 PM EST. The solicitation number is OAA-26-00018, and it is currently in the pre-solicitation stage. An amendment was issued on 12/19/25 to incorporate vendor questions, though the response submission date remains unchanged. The federal agency conducting this procurement is the Department of Labor Office of the Assistant Secretary for Administration and Management.

Sheet1
| Section | Question | Response |
| SOW | Do you have any specific requirement for what types of sample holders can be used with the automated sample changer (for example, 51.5 mm or 40 mm holders)? | There is no specific requirement for type of sample holder, as long as it does not affect the compatibility of the sample holder with the instrument. The sample holder also must be able to hold 25 mm diameter silver membrane filters used for deposition of crystalline silica. |
| SOW | What does it mean by “ a function of the automatic sample holders that can accommodate 25-mm diameter silver membrane filters"? Could you please provide more details about this? | OSHA makes depositions of crystalline silica samples on 25 mm diameter silver membrane filters. The sample holders must be able to hold these filters for analysis. |
