Axiom Analytical, Inc. Releases the FDR-825 Self-Cleaning Diffuse Reflectance Probe for Non-Contact Analysis

Axiom Analytical, Inc. has announced that its self-cleaning, fiber-optic coupled FDR-825 Diffuse Reflectance Probe is now in full-scale production. Operating in the near-infrared (near-IR) and visible spectral regions, the new probe has been designed to yield optimum performance for the analysis of powders, slurries, and other diffusely reflecting materials.

A unique feature of the new probe is the provision of a set of orifices around the circumference of the probe window positioned so as to allow efficient flushing of the window by a solvent or dry vapor stream.

The proprietary optical design of the FDR-825 provides a unique combination of high sensitivity, low stray light, and large depth-of-field and is suitable for use at substantial distances from the material being analyzed. Its variable offset feature allows the optimum sample distances to be set anywhere between 50 mm and infinity. The probe’s integral bifurcated 80 fiber-optic bundle provides an ideal combination of sensitivity and economy.

The FDR-825 is being applied in fields such as chemical and pharmaceutical development as well in process analytical technology (PAT) modeling and scale-up. Methods developed using the FDR-825 can be applied on-line in full-scale process analysis in batch reaction vessels using the Company’s large scale diffuse reflectance probes such as its model FDR-1800.
