About this file
This notice announces the National Oceanic and Atmospheric Administration's intent to negotiate a sole source contract with Handix Scientific, Inc. for the purchase of 18 Portable Optical Particle Spectrometers, model POPS-1100, for use by the Chemical Sciences Laboratory in Boulder, Colorado. Delivery of the spectrometers is required by November 1, 2023. The sole source determination is based on Handix Scientific being the only vendor currently producing the POPS-1100, which is uniquely capable of particle detection below 150 nm while maintaining a small size, low power consumption, and weight suitable for field research use. While other low-cost optical particle counters are available, they are designed for industrial use and lack the POPS-1100's claimed low detection limit and performance in measuring background aerosol concentrations in the upper troposphere and lower stratosphere.

SPECIAL NOTICE
NRMJ30002301121SRG
*** National Oceanic and Atmospheric Administration's (NOAA) Acquisition & Grants Office, Western Acquisition Division-Boulder, intends to negotiation, on a sole source basis, under authority of FAR 13.106-1(b)(1), with Handix Scientific, Inc., to purchase of a quantity of 18 Portable Optical Particle Spectrometer Brand: Handix; Model: POPS-1100 (Core system without enclosure) for the Office of Oceanic and Atmospheric Research (OAR) Chemical Sciences Laboratory (CSL) Boulder, CO Office.
***The sole source determination is based on the NOAA/OAR/CSL, requirement that Handix Scientific, Inc. is the only vendor that currently produces the Portable Optical Particle Spectrometer (POPS). The POPS sensor is unique among research grade optical particle counters (OPC) in its combination of small size, weight and power consumption while achieving a low particle size detection limit below 150 nm (0.15 μm). There are a number of low-cost OPCs available [e.g. AlphaSense OPC-N2, Plantower PMSx003, Shinyei PPD42NS], but they are designed for industrial or air quality applications and none have a claimed detection limit below 0.3 μm and a number of assessments indicate their performance is of limited quality below 0.5 μm or even 1 μm particle diameter. With these minimum detectable sizes, most of the aerosol number in background conditions are not measured and they would be of no value for measurements in the upper troposphere and lower stratosphere.
Delivery will be by November 1, 2023 or sooner.
***This notice of intent is not a request for competitive proposals and no solicitation package is available. However, firms that believe they can fully meet the Government’s requirements may submit substantiating documentation in writing to the identified point of contact within 15 days after publication of this synopsis. Such documentation will be evaluated solely for the purpose of determining whether or not to conduct this procurement on a competitive basis. A determination by the Government not to conduct a competitive procurement, based upon responses to this notice, is solely within the discretion of the Government. Oral communications are not acceptable in response to this notice.
