12. Clean the injector body.
a. Ultrasonically clean the injector insert using a warm 1% Liquinox™ solution (or
equivalent).
b. Thoroughly rinse the insert then ultrasonically clean in chromatographic grade
methanol or acetone followed by solvents of lower polarity such as methylene
chloride and hexane. Limit ultra-sonication to 5 min in each solvent.
c. Blow dry the insert using high purity gas (do not use compressed house air as it
contains residual oils from the compressor) then assemble in the reverse order of
removal.
