ATR-Loop InfraRed Fiber Optic Probes

  • 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

 

 

 

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 perfect for remote analysis of composition of liquids, pastes and soft surfaces with no need in sample preparation.
 
Loop fiber probe is the simplest one in FlexiSpec® product family to enable low cost ATR-spectroscopy.
 
Applications:
  • Remote evanescent absorption (ATR-) spectroscopy in-citu
  • Multiple ATR-spectroscopy by immersion of fi ber loop in liquid
  • In-vivo molecular spectroscopy for medical diagnostics by simple touch of ATR-Loop to skin or tissue
