Fiber Optic ATR Loop Probe

Main features

  • High throughput at Mid InfraRed range
  • On-line absorbance spectroscopy of liquids, pastes & soft solid surfaces
  • Compatible with all FTIR, QCL and IR- Filter spectrometers
  • Cost effective alternative to more expensive ATR-IR-fiber probes
  • Replaceable ATR Loop PIR-Fiber Tips

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.
