Pursuant to RFO 5.101(c)(4)(vii), the following identifies the intended source and explains why competition is not practicable for this requirement.
Intended Contractor:
Photothermal Spectroscopy Corp.
325 Chapala St Santa Barbara, CA 93101
CAGE Code: 83PQ8
The basis for limiting this solicitation to a single source is that only one source is reasonably available, consistent with RFO 13.101(b) and the single-source standard at RFO 12.201-1(c).
Photothermal Spectroscopy Corp “PSC” is the one and only supplier that can meet the performance requirements outlined in the Statement of Work. The counter-propagating mode upgrade must be 100% compatible with the existing Photothermal mIRageLS to provide a seamless integration and establish full system communication and control through the single, existing software currently at FDA. PSC owns the patent for intellectual property protecting the O-PTIR technology and its associated capabilities. O-PTIR is protected by multiple patents and is exclusively available from Photothermal Spectroscopy. PSC will be the only provider to support the FDA in this requirement of the necessary parts and knowledgeable installation team to ensure 100% compatibility of the upgrade with the current FDA instrument. Photothermal is a US company and is a registered small business. A Brand Name acquisition is recommended, since only one provider meets the requirements for the acquisition.
A written single-source justification has been prepared and approved in accordance with RFO 12.201-1(c) and RFO 13.101(b).
The contractor must provide a counter-propagating configuration upgrade for the mIRageLS Optical-Photothermal Infrared-Raman-Fluorescence (O-PTIR-R-FL) Microscope. The upgrade must include optical components for sub-500 nm spatial resolution, quantum cascade laser-based IR illumination, transmission detection, and seamless integration with the existing system. The contractor must also provide installation and ensure full system communication and control through the existing FDA software.
