Maintenance schedule – nebulizer/spray chamber
Daily
Clean the nebulizer/spray chamber assembly thoroughly at the end of
every working day by aspirating at least 50 mL of the appropriate solvent
through the system.
Test all connections for leaks with a brush and soap solution or a
proprietary leak-detecting solution. Never use a naked flame when testing
for leaks. Rectify all leaks before lighting the flame.
Test the nebulizer for leaks. If any leakage is detected, replace the internal
O-rings.
Monthly
Remove and check the nebulizer, re-install the nebulizer (outlined in the
following section) and measure the uptake rate to verify the Performance
checks– see Page 85.
