Air quality of compressed air FOR NITROGEN generators for LCMS, and zero air :
ISO 8573.1 CLASS 1.2.1

The new international standard for compressed air quality introduces a simple classification system for the 3 main contaminants present in any compressed air system : dirt, water and oil.

Quality class	Dirt Particules size in micron	Water Pressure dewpoint °C at 7 bar	Oil Including vapor mg/m3
1	0,1	-70°C	0,01
2	5	-40°C	0,1
3	10	-20°C	1
4	40	3°C	5
5	-	7°C	25
6	-	10°C	-

Note :

If the LCMS nitrogen generator is connected to a non-lubrificated compressor, the fridge dryer is efficient.

If the compressor is lubrified, it is recommended to use an adsorption dryer.
