Introducing the FlexiSpec Combi Fiber Optic Probes

In the demanding fields of bio-pharma and advanced R&D, real-time data is essential. Traditionally, securing comprehensive analytical data meant physically switching between different spectroscopic setups, such as ATR, NIR, and Raman. This fragmented approach not only slows down critical processes but also introduces a higher risk of sampling errors. Why run three separate analyses when […]

CPACT Webinar: Bridging the Gap from the Lab to Real-Time Process Control

Transitioning from offline sampling to real-time, in-line monitoring remains one of the most significant bottlenecks in Process Analytical Technology (PAT) today. When process engineers are forced to wait on delayed lab results, it impacts both efficiency and process optimization. To help address this challenge, art photonics is proud to announce an upcoming webinar hosted by […]

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.
