In Brief This glossary defines the technical vocabulary used in TDLAS-based gas analysis, from the spectroscopy fundamentals through instrumentation, performance metrics, and system integration. The definitions are practical rather than academic: they focus on what...
In Brief Greenhouse gas monitoring requires measurements that are selective, stable over months, and fast enough to capture short-duration emission events. TDLAS meets these requirements for CO₂, CH₄, N₂O, and H₂O by referencing each measurement to a molecular...
In Brief Leak detection and repair (LDAR) programmes require instruments that distinguish the target gas from background species, respond fast enough to localise the source while the operator is still at the measurement point, and hold their calibration across a full...
In Brief Tunable diode laser absorption spectroscopy (TDLAS) measures gas concentration by scanning a narrowband laser across a molecular absorption line and quantifying the attenuation of the beam through the gas. The measurement is tied to a physical property of the...
In Brief Selecting a gas analyzer starts with the measurement requirement, not the technology. Define the target gas, the concentration range, the required response time, the process matrix, and the installation geometry. Then match these requirements to the...
