METTLER TOLEDO Publishes eBooklet: “Tunable Diode Laser Spectroscopy – Theory and Background”


Source: Mettler - Toledo Int. Inc

METTLER TOLEDO Process Analytics has launched an eBooklet discussing the theory of Tunable Diode Laser (TDL) absorption spectroscopy and how TDL analyzers are being employed in an increasing number of process and safety-critical industry applications.

Since their first use in the 1990s, Tunable Diode Laser gas analyzers have seen rapid growth in industry due to their exceptional performance and reliability. Today, TDL spectroscopy continues to make technical advances, making this class of sensor the preferred choice by many chemical and petrochemical companies.

This booklet is intended as an introduction to the field of tunable diode laser spectroscopy (TDLS) and its applications for different analytical tasks. A special emphasis is placed on process analytics and the re¬quirements of a range of measurement environments. Included in the booklet are topics such as advantages for TDL in process gas analytics, some of the most common application examples for TDLs in process analytics, signal processing techniques for TDL spectroscopy, and wavelength spectroscopy among others.
