TDL (Tunable Diode Laser) Gas Analyzers

Rethinking gas analytics

Interference-free, drift-free TDL technology offers better process control and lower maintenance costs.

However, for reliable measurement with a TDL sometimes necessary framework conditions such as minimum optical path length, the availability of a purge gas supply and/or maximum dust load get in the way. Acknowledging these constraints, METTLER TOLEDO has developed specific process interface solutions that substantially increase the coverage of possible TDL applications. Based on the folded optical path principle, METTLER TOLEDO range of compact TDL spectrometers and unique process adaptions, for process, safety, combustion, and vapor recovery applications are essential instruments for improving your processes:

No need for alignment:With laser source and detectors on the same side, the GPro 500 standard (SP) probe does not need alignment, and fits in pipes down to DN100

For inerting and blanketing applications:With its probe specially designed for static process conditions the GPro 500 with NP probe allows reliable inertization control for increased safety and lower purge gas consumption.

Measurement location in small pipes:For DN 50 or 2 pipes where no flow restriction is allowed, the GPro 500 Wafer Cell allows precise and stable measurements even in harsh process gas streams.

Ideal for combustion applications:Where very high dust loads will typically obstruct measurement on longer optical paths, the GPro 500 with a Filter probe enables robust measurement in fired heaters and boilers.

Compatible with existing extractive solutions:If an extractive analyzer is already fitted, shorter response times and lower maintenance costs can be obtained by retrofitting the GPro 500 with an Extractive Cell adaption into your current sampling and conditioning system

FAQ

1. A tunable diode laser gas analyzer is what, exactly?

Ans - An apparatus known as a tunable diode laser gas analyzer (TDLA) utilises lasers to calculate the concentration of particular gases in a sample. By measuring the laser beam's strength, it is possible to determine the concentration of a gas since the laser beam is adjusted to a certain wavelength that is absorbed by that gas.

2. Just how precise are TDLAs?

Ans - TDLAs have a resolution of parts per billion (ppb), making them incredibly accurate. They are therefore perfect for uses including monitoring pollutants, the environment, and industrial process management.

3. What kinds of gases can a TDLA measure?

Ans - Numerous gases, including nitrogen (N2), carbon dioxide (CO2), methane (CH4), and oxygen (O2), can be measured using TDLAs.

4. How do TDLAs operate?

Ans - A TDLA measures the amount of light absorbed after a laser beam passes through a sample of gas. The concentration of a gas can be determined by tuning the laser's wavelength to a certain frequency that is absorbed by that gas.

5. What are the benefits of TDLA use?

Ans - In comparison to other methods of gas analysis, TDLAs have a number of benefits, such as extremely accurate readings, quick response times, and low cost. They also require little upkeep and are generally simple to use.
