Mettler-Toledo TDL analysers receive Frost & Sullivan award

Based on its recent analysis of the process tunable diode laser (TDL) analysers market, Frost & Sullivan has recognised Mettler-Toledo AG with the 2014 Global Frost & Sullivan Award for Competitive Strategy Innovation & Leadership. Mettler-Toledo's TDL series, the GPro 500, has an original design that is adaptable to almost any kind of process. The series comprises four separate products for the measurement of oxygen, carbon monoxide, carbon dioxide and moisture.

Mettler-Toledo's GPro 500 TDL series can be used for both in-situ and extractive measurement. In-situ measurement is increasingly preferred by customers, as direct measurement in the process is fast and reliable. Others prefer extractive systems where a sample of the gas is literally extracted from the gas stream before measurement. The GPro 500 combines the laser source and analyser in a single unit. The laser beam from the source passes down a probe and is reflected by a three-sided mirror back up the probe to the analyser. This design makes alignment unnecessary.

The GPro 500 TDL series is available with a range of adaptions that fit directly to the analyser's head. These adaptions are the reason for the GPro 500's flexibility in application. Most TDLs use a large quantity of purge gas to prevent the analyser's optics from being coated by dust in the gas stream. The GPro 500 is available with a robust probe fitted with a shielded particle filter that eliminates the need for purge gas. The series also has a wafer cell, which enables accurate measurement in confined spaces such as 5 cm pipes. Previously, this has not been possible with TDLs.

"Mettler-Toledo stands out for its ability to integrate unique and standout features into its product line. Unlike competing solutions, the GPro 500 TDL series is compact and lightweight and, therefore, easy to install," said Frost & Sullivan Research Analyst Janani Balasundar. "Furthermore, the company collaborates with various local approval boards to ensure compliance with regulations. For example, FM Global certification is a key requirement in petrochemical plants globally, particularly in the United States, a requirement that is satisfied by the GPro 500 TDL series."
