Installation of Capillary Column (Vespel Ferrule)

Required parts¶

Procedure¶

Step 1¶

Allow GC/MS to come to an automatic stop. Wait until [Completed] is displayed.

Step 2¶

Insert your hand inside the door opening and open the oven door.

Step 3¶

Using the torque wrench(⑤⑥), remove the nut on the injection side.

Step 4¶

Using the torque wrench, remove the nut on the mass spectrometer side.

Step 5¶

Remove the column(④) from the column hanger.

Step 6¶

1. Pass the injection side of the column to be used through the nut(⑦).
2. Pass the column through the Vespel ferrule(⑧).

Step 7¶

Pass the column through the column attachment jig (for INJ)(①).

Step 8¶

1. With at least 1 cm of the tip of the column protruding out, tighten the nut. First tighten by hand, then use a torque wrench until it "clicks," indicating that the specified torque is reached.

2. Cut the protruding part of the column using the column cutter(③).
3. Attach a tape or septum at the end of the nut as a guide for positioning.

Step 9¶

Remove the column and nut from the column attachment jig.

Step 10¶

Following the same procedure used for the injection side, pass the mass spectrometer side of the column through the nut and Vespel ferrule.
Secure the column to the column attachment jig (for MS)(②).

Step 11¶

In the same way as with the injection side, cut the tip of the column and mark the positioning guide.

Step 12¶

Before attachment, wipe the column tip part (from the tips on the injection side and mass spectrometer side to the nuts) using a soft cloth soaked with acetone to remove any dirt adhesion.

Step 13¶

Attach the column to the instrument.

1. When attaching the column, tighten the nut while lightly pushing the positioning mark (tape or septum) against the nut.
2. First tighten by hand, then use a torque wrench until it "clicks," indicating that the specified torque is reached.

Step 14¶

Remove the positioning mark (tape or septum).
After checking that the column is fixed to the injection side and mass spectrometer side, close the GC column oven door.

Step 15¶

Launch the [Analysis] program.

1. Either click the [System Configuration] icon in the [Main] assistant bar, or click [Instrument] on the toolbar and then click [System Configuration].

2. In the system configuration, double-click [Column] in the modules used for analysis, or select [Column] and click the [Properties] button.

Step 16¶

1. Click the [Column] tab to open the column's system configuration screen.
2. When using a new column, you need to enter the name, type, inner diameter, and length of the column, as well as the film thickness of the liquid phase and operating temperature range. If necessary, additionally enter the starting date of use of the column, option items, and comment.
   When using a column registered in the column list, click [Refer to Column List] and select the column that you want to use for analysis.
3. After completing the setup, click the [OK] button.

4. Click [OK] in the [System Configuration] window to exit system configuration.
