Cleaning the PTV Injector Head Assembly
260 TRACE 1600/1610 Hardware Manual
Perform this operation when cleaning the injector head assembly is desired or required, due to
contaminants.
WARNING This operation must be carried out by authorized and trained Thermo Fisher
Scientific Service Field Engineers.
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 head assembly
Materials needed
Ultrasonic cleaning bath
GC-grade methanol/acetone mixture 1:1
1/8-inch -wrench
5.5 x 25 mm Slotted Stubby Driver
T10 Torxhead screwdriver
Forceps or tweezers
1. Put the GC in standby condition.
2. Cool the oven, injectors, and detectors to room temperature.
Note By pressing the Maintenance button, the GC cool down is automatically
carried out.
3. Power off the GC.
a. Pull down on the power switch (breaker), located at the back of the instrument, to
the position O.
b. Unplug the power cable from the AC Input connector on the back of the GC, and
from the wall outlet.
4. If external modules are present, unplug the power cable from the AC Input connector of
each external module, and from the wall outlet.
5. Close the gas supplies.
6. Put the autosampler away if present.
7. Remove the top parts of the injector. See Figure 227.
