On the instrument monitor or workstation, check that the temperature of the column oven is lower than 40 °C, and check that the temperatures of the injection port and detector are 50 °C or lower.
After checking the temperatures, turn OFF the main power to the instrument.

Step 2¶

Remove the column installed on FID.

Step 3¶

Open INJ/DET cover.

Step 4¶

Remove the screw fixing the clamp for high voltage cable, and remove the clamp.

Step 5¶

Loosen the screw on the near side of the collector holding hardware.

Step 6¶

Remove the screw on the far side of the collector holding hardware.

Step 7¶

Slide the collector holding hardware clockwise.

Step 8¶

Raise the collector (③) to remove it.

Step 9¶

Remove the connector of the signal code.

Step 10¶

Raise the sheet metal fixing the high voltage electrode to remove it.
