The MS requires ultra-high-purity (UHP) and high-purity (HP) supply gases for optimal performance. Ensure that the laboratory site meets the gas requirements as listed in the following table.

NOTE

If the location of your gas supply exceeds the length of the provided tubing, you must provide suitable tubing for the gas connections. Consumption values are approximate when operating 24 hours and 7 days a week.

CAUTION

Contaminants in the laboratory gas lines can cause damage to the instrument. Make sure that all gas lines have been cleaned of all particulates and oils. You must use either copper (provided) or stainless steel for the UHP gas lines. Avoid using particulate filters, as they can be a source of contamination. You are responsible for any damage to the instrument caused by contaminants introduced from your gas delivery system.
