Application Note: Identification of Organic and Pharmaceutical Powders

Real-time, in-line powder identification usually means a trade-off between speed and accuracy. We proved it doesn't have to. We recently teamed up with our Nynomic Group partner, m-u-t GmbH, to release a joint Application Note. The goal was simple: build a compact, field-ready NIR setup capable of analyzing complex organics directly in the bulk material, […]

Description

FlexiSpec® product line includes the latest generation of Transmission  fiber optic probes to be used with any spectrometer or photometer  in any part of UV –Vis or Vis – NIR spectra. Sapphire windows  allow to use Transmission probe  in wide range of liquids.

By request probe shaft can be  electrically heated to prevent moisture condensation on optical windows.

Stainless Steel or Hastelloy C22 schaft is suitable for the work in harsh environment.  Transmission  fiber optic probes are compatible with process-interfaces to ensure the cleaning and reaction monitoring in lab, pilot plant and industrial setup to  run process control.
