Cleaning the SSLBKF Injector Body
252 TRACE 1600/1610 Hardware Manual
Perform this operation when a more efficient cleaning of the injector body is desired or
required, due to contaminants.
Note Some of the cleaning procedures in this section require the use of methanol.
If methanol is unavailable or prohibited, substitute LCMS-grade or GC-grade ethanol
or isopropyl alcohol. Do not use denatured ethanol as it may contain impurities that
contaminate the GC-MS system.
 To clean the injector body
Materials needed
Ultrasonic cleaning bath
Methanol/acetone mixture 1:1
GC-grade methanol
1/8-inch -wrench
T20 Torxhead screwdriver
Forceps or tweezers
1. Put the GC in standby condition.
