If the supply of compressed nitrogen from a storage facility (gaseous in pressure vessels or as liquid nitrogen with subsequent evaporation) is still qualitatively secured by a Certificate of Analysis (CoA) from the nitrogen manufacturer, it becomes more difficult for the compressed air produced on site: The compression takes place using the ambient air as a resource, which can be very different in various locations or can be strongly affected by environmental influences which have a direct impact on the quality.
