TDLAS Gas Analyzer With Gas Conditioning System High Temperature Extraction Type Monitoring HCL/HF/NH3
TDLAS stands for tunable diode laser absorption spectroscopy. It is a type of laser spectroscopy that is used to measure the concentration of gases in a sample. TDLAS is a very sensitive technique, and it can be used to measure the concentration of gases in very small amounts of sample.
TDLAS works by using a laser to excite the molecules in a sample. The laser is tuned to a wavelength that corresponds to the absorption spectrum of the molecule of interest. When the laser light is absorbed by the molecules, it causes them to emit light at a different wavelength. The amount of light that is emitted at the different wavelength is proportional to the concentration of the molecule in the sample.
TDLAS is a very versatile technique, and it can be used to measure the concentration of a wide variety of gases. It is also a very accurate technique, and it can be used to measure the concentration of gases in very small amounts of sample.
TDLAS is used in a variety of applications, including:
- Environmental monitoring
- Industrial process control
- Medical diagnostics

What is the difference between a gas chromatograph and a mass spectrometer?
A gas chromatograph (GC) is an analytical instrument that separates compounds based on their boiling points. A mass spectrometer (MS) is an analytical instrument that separates compounds based on their mass-to-charge ratio.
GCs and MSs are both used to analyze gases, liquids, and solids. However, GCs are more commonly used to analyze volatile compounds, while MSs are more commonly used to analyze non-volatile compounds.
GCs work by passing a sample through a column that is coated with a stationary phase. The stationary phase is a material that selectively absorbs different compounds in the sample. The compounds that are more strongly absorbed by the stationary phase will spend more time in the column and will elute later than the compounds that are less strongly absorbed.
MSs work by ionizing the molecules in a sample and then accelerating them into a mass analyzer. The mass analyzer separates the ions based on their mass-to-charge ratio. The ions that are more massive will have a lower mass-to-charge ratio and will be deflected less by the mass analyzer.
GCs and MSs can be used together to provide a more comprehensive analysis of a sample. The GC can be used to separate the compounds in the sample, and the MS can be used to identify the compounds.
