Analyttene

Analyttene are the substances of interest measured in a sample in analytical chemistry. They can be a single chemical species or a group of compounds, including inorganic ions, organic molecules, or biomolecules. The term is used to distinguish what is being analyzed from the sample matrix and the measurement process.

In practice, identifying and quantifying analyttene is essential across fields such as environmental monitoring (pollutants in water and air), clinical chemistry (hormones, metabolites, drugs), pharmacology (drug levels in plasma), and food safety (contaminants and additives). The selection of analyttene depends on the purpose of the analysis and regulatory requirements, as well as the analytical method available.

Analytical methods detect analyttene using instrumentation such as high-performance liquid chromatography (HPLC), gas chromatography (GC), tandem mass spectrometry (MS/MS), UV–visible spectroscopy, or immunoassays. Quantification typically relies on calibration with standards, along with quality control procedures. Sample preparation may be required to extract or concentrate the analyttene and to remove interfering substances, thereby improving accuracy and sensitivity.

Etymology and usage: The term is borrowed from English analyte, used in Norwegian and other languages to denote substances subject to analysis; the definite plural form is analyttene. While “analytt” may appear in technical writing, the international literature often uses the English term. The concept of analyttene underpins how laboratories report concentrations, identities, and the presence of target compounds in diverse samples.
