sekaantumatonta

Seakaantumatonta is a Finnish adjective meaning not mixed with other substances or influences; uncontaminated or unmixed. It describes a state in which something remains free from contamination, alteration, or external involvement. The base form is sekaantumaton, and sekaantumatonta is the partitive singular form used before a noun referring to an indefinite quantity or mass, for example sekaantumatonta vettä (uncontaminated water).

In practice, sekaantumatonta is most common in technical, scientific, and quality-control writing. It is used to characterize samples, materials, or data that have not been mixed with other substances or subjected to external interference. It contrasts with forms such as sekaantunut or kontaminoitunut, which indicate mixing or contamination. The term can also appear in broader formal contexts to emphasize purity or integrity of information, procedures, or objects.

Morphology and related terms: the adjective derives from the verb sekaantua (to become involved or mixed) and the negative suffix. Related concepts include sekaantuminen (the act of becoming involved or mixing), sekaantumaton (the nonparticiple form meaning unmixed/uncontaminated), and kontaminaatio (contamination), which is often used as the counterpoint in technical writing.

Examples of usage: sekaantumatonta vettä, sekaantumatonta näytettä, sekaantumatonta dataa. While common in scientific and industrial contexts, the word is less frequent in everyday speech, where more general terms for purity or integrity may be used.
