UHP nitrogen, or Ultra High Purity nitrogen, refers to nitrogen gas with a purity level of 99.999% (5N grade) or higher. It contains extremely low concentrations of impurities such as oxygen, moisture, hydrocarbons, and other trace gases. This level of purity is essential for sensitive analytical, semiconductor, and research applications where even trace contamination can compromise results.
