Gassanalyse

Gassanalyse is a term used to describe the analysis of gaseous samples to determine their composition, concentration, and physical properties. In practice, gassanalyse encompasses a range of analytical approaches and technologies, rather than a single method, and is applied across environmental science, industry, and medicine.

Common techniques include gas chromatography (often coupled with mass spectrometry), infrared and Raman spectroscopy, and electrochemical sensing. Sampling can be performed on-site or in the laboratory, using methods such as gas bags, sorbent tubes, or direct-line probes. Analytical work typically involves calibration with known standards, quality control checks, and data processing to quantify individual gas components.

Applications include monitoring ambient air for pollutants and greenhouse gases, detecting combustible or toxic leaks in industrial settings, controlling combustion and energy processes, and exploring biomarkers in breath analysis for health research.

Challenges in gassanalyse include dealing with complex mixtures, overlapping spectral features, and matrix effects; accuracy depends on calibration, instrument maintenance, and method validation. Harmonization of reporting units and detection limits is common across laboratories.

Pronunciation and spelling vary; the term is often linked to the German word Gasanalyse and the English phrase gas analysis, with gassanalyse as a stylized or brand-like form used in some contexts.
