The FDR-825 fibre-optic coupled diffuse reflectance probe from Axiom is designed for optimum performance in the analysis of powders and slurries in pharmaceutical development and process monitoring.
The probe operates in the near-infrared (NIR) and visible spectral regions and is designed to yield optimum performance for the analysis of diffusely reflecting materials.
A feature of the 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 vapour steam.
The optical design of the FDR-825 provides a combination of high sensitivity, low stray light, and large depth-of-field, and is suitable for use at substantial distances from the material being analysed.
Its variable offset feature allows the optimum sample distances to be set anywhere between 30 and 100mm.
The probe's integral bifurcated 80 fibre-optic bundle provides an ideal combination of sensitivity and economy.
Axiom Analytical expects the FDR-825 to find application in fields such as chemical and pharmaceutical development as well as in process analytical technology (PAT) modelling 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.
