What is role of degassing in HPLC?

Some points on role of degassing in HPLC are:

• Degassing reduces the concentration of dissolved air in the mobile phase before it enters the high-pressure pump.
• It removes oxygen and nitrogen that can come out of solution when pressure conditions change inside the HPLC system.
• Degassing limits gas solubility effects that occur when solvents are compressed during pumping.
