Trace Gas Analyzer TDLAS Technology Ppb To Ppm Measurement Online 19"4U Type
A trace gas analyzer is a device that measures the concentration of a trace gas in a sample. Trace gases are gases that are present in small amounts, typically at concentrations of less than 1%. Trace gas analyzers are used in a variety of applications, including environmental monitoring, industrial process control, and medical diagnostics.
There are a number of different types of trace gas analyzers, each with its own advantages and disadvantages. The most common type of trace gas analyzer is the infrared absorption spectrometer. Infrared absorption spectrometers work by measuring the amount of infrared light that is absorbed by a gas. The amount of infrared light that is absorbed is proportional to the concentration of the gas.
Other types of trace gas analyzers include mass spectrometers, electrochemical sensors, and chemiluminescent detectors. Mass spectrometers work by separating the gas molecules into their constituent atoms and ions. Electrochemical sensors work by measuring the electrical current that is generated when a gas reacts with an electrode. Chemiluminescent detectors work by measuring the amount of light that is emitted when a gas reacts with a chemical reagent.
The choice of which type of trace gas analyzer to use depends on the specific application. For example, infrared absorption spectrometers are well-suited for applications where the concentration of the gas is relatively high. Mass spectrometers are well-suited for applications where the concentration of the gas is very low. Electrochemical sensors are well-suited for applications where the gas is reactive. Chemiluminescent detectors are well-suited for applications where the gas is easily detected by a chemical reaction.
Trace gas analyzers are an important tool for a variety of applications. They are used to monitor environmental pollution, to control industrial processes, and to diagnose medical conditions. Trace gas analyzers are also used in research and development to study the properties of gases and to develop new technologies.
