The APCI spray chamber operates at high temperatures. Allow sufficient time to
cool down before handling.
Some mobile phases are dangerous. Use the degree of caution appropriate for the
mobile phase being used.
Do not spray the mobile phase upward into the vaporizer.
Do not spray directly toward the tip of the capillary. This can cause pressure surges in
the vacuum system.
