Application Note: Measuring Ethanol and Methanol Mixtures with ATR Fiber Probes

In the high-stakes environment of complex chemical processing, the ability to distinguish and quantify components like ethanol and methanol in real-time is often the deciding factor between a strictly controlled reaction and an off-spec batch. Traditionally, operators have relied on manual extraction for laboratory analysis. However, this method introduces significant delays and safety risks that […]

How to Measure ATR Spectra Directly in Solution with Fiber Optic Probes

Moving Beyond the Bench: In-Line FTIR Monitoring with ATR Probes For decades, Attenuated Total Reflection (ATR) has been a standard technique for FTIR spectroscopy. However, most users are restricted to standard ATR inserts or benchtop accessories. While effective for static lab samples, these setups introduce a critical bottleneck: the sample must be extracted from the […]

Categories: , Tag:

Main features:

  • High transmittance in selected parts of 3 - 17μm range for customized applications
  • No Fresnel reflection at the end faces
  • Inner diameter spans from 500 to 1000μm
  • Double polymer coating for high flexibility

Description

Hollow Silica Glass IR-Fibers  (Hollow Glass Waveguides) design is a perfect option to transmit a low divergent IR-light of Mid IR-spectrum from 3 to 17μm. High performance fibers are produced with core diameters span from 500µm to 1000µm with double polymer jacket to secure a superior mechanical strength and high flexibility of HGWs.

Low optical losses at the selected spectral windows without Fresnel reflection enable a broad variety of HGW applications in Mid IR-range.
