Understanding the Power of Infrared Spectroscopy in CEIRS™


Table of contents



CEIRS™, short for Chilled-mirror Evanescent Infra-Red Spectroscopy, utilizes the power of infrared (IR) spectroscopy to revolutionize dew point measurement. This document explores how IR spectroscopy elevates CEIRS™ above traditional methods.

Challenge of Traditional Chilled-Mirror:

While the chilled-mirror principle has been established for a while, precisely identifying the onset and nature of condensation remained a challenge. IR spectroscopy effectively addresses this issue.

IR Spectroscopy Explained:

Spectroscopy, a common technique in science, analyzes how light interacts with different molecules. Each molecule interacts uniquely with specific light wavelengths, categorized by type (UV, Vis, NIR, IR) or technique (Absorption, Raman).

This text focuses on IR absorption spectroscopy, crucial for CEIRS™ in detecting hydrocarbon and water dew points in natural gas.

IR Spectroscopy: Unveiling the Molecular Fingerprint:

IR light interacts with molecules, causing specific vibrations. These vibrations lead to the absorption of specific IR wavelengths, forming a unique fingerprint spectrum for each molecule, and allowing identification.

Versatility of IR Spectroscopy:

IR spectroscopy finds applications in various fields like pharmaceuticals, materials science, medicine, and environmental science. Its ability to identify compounds, quantify substances, and monitor real-time reactions makes it a valuable tool across diverse scientific domains.

Spectroscopic Analysis in Action:

Imagine IR light interacting with a sample, causing molecular vibrations. The resulting absorption spectrum provides detailed information about the sample's molecular composition, enabling accurate identification and quantification.

CEIRS™: A Leap Forward in Dew Point Detection:

ZEGAZ Instruments' CEIRS™ technology integrates IR spectroscopy with the chilled-mirror method, marking a significant advancement in dew point measurement.

CEIRS™ and IR Spectroscopy:

Unlike conventional chilled-mirrors, CEIRS™ instruments utilize IR spectroscopy for dew point detection. They direct IR light onto a chilled mirror and analyze the resulting spectrum. This analysis detects subtle changes indicating the phase transition at the dew point temperature.
