Ohutkaasut

Ohutkaasut, often translated as "thin gases" or "rare gases," is a Finnish term that can refer to gases present in very low concentrations in the atmosphere or in specific industrial or scientific contexts. In atmospheric science, it generally pertains to trace gases that, despite their low abundance, can play significant roles in atmospheric processes, such as climate regulation or air quality. Examples include methane, ozone, and nitrous oxide. Their monitoring is crucial for understanding environmental changes.

In other fields, ohutkaasut might describe gases used in specialized applications where purity and minimal presence of other substances are critical. This could include gases used in semiconductor manufacturing, vacuum technology, or certain analytical instruments. The term emphasizes the high purity or the deliberate low concentration of the gas of interest, distinguishing it from bulk gases. The specific meaning of ohutkaasut depends heavily on the context in which it is used, but it always implies a state of low concentration or high purity.
