Analyytit

Analyytit refer to the substances that are the subject of an analytical measurement. In Finnish, analyytit (plural) denotes analytes and describes chemical species, biomolecules, or other compounds that are being measured or identified in a sample. The concept is central across analytical chemistry, environmental science, clinical diagnostics, and food safety.

In an analysis, the goal is to identify the analyte's identity and to quantify its amount. Measurements are performed using methods that separate, detect, or quantify the analyte against calibration standards. Results are reported in concentration units such as mg/L, µM, or ng/g, or as other appropriate mass- or amount-based measures. The sample matrix and potential interferences can affect accuracy, so sample preparation, method validation, and quality control are important components of the process.

Common examples of analyytit include environmental contaminants (heavy metals, pesticides), nutrients and metabolites (glucose, cholesterol), pharmaceutical ingredients and impurities, and biological markers (proteins, hormones). Analytical methods vary by the properties of the analyte and the required sensitivity, with examples including chromatography coupled to mass spectrometry, UV–Visible spectroscopy, immunoassays, and electrochemical detection.

Notes: the term analyte is widely used in science, and analyytit is the Finnish plural form describing those substances being analyzed. Analytical laboratories emphasize validation, traceability to standards, and quality assurance to ensure reliable measurements.
