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

The ATR-Loop Infrared PIR-fiber probe was the first in FlexiSpec® product line designed for use with FTIR and other Mid IR spectrometers. ATR-Loop PIR-fiber probes are well-suited for remote analysis of composition of liquids, pastes and soft surfaces and do not require sample preparation. The Loop fiber probe is the simplest one in the FlexiSpec® product family to allow for low cost ATR-spectroscopy. Loops with different number of turns (single, double or triple) serve to fit the desired sensitivity.
