Maintenance works must only be undertaken after the temperature of each part has been lowered to less than 50 deg.C.
Place any detached items on a clean sheet or tray. Do not lose or contaminate these items.
Undertake the works using the appropriate tools. Any dirt on the tools being used must be wiped off in advance using gauze etc. dipped in acetone.
10x12 wrench (standard accessory), two 6x8 wrenchs (standard accessory), capillary cutter (option, Part No. 221-50595-91)

Shutdown the system. |

Pass the capillary column entrance side through a hexagon cap nut and the graphite ferrule. Cap nut 221-16325-01 Graphite ferrule 0.5mm 221-32126-05 Graphite ferrule 0.8mm 221-32126-08 |

Fix the graphite ferrule provisionally using the graphite fixing jig. When doing so, let the capillary column protrude about 10mm from the graphite fixing jig, and cut the column using a capillary cutter etc. at the tip of the fixing jig. If the fixing jig for the SPL is used, the position will be fixed at 34mm from the column tip. Capillary cutter 221-50595-91 |

Using the fixing jig, fix the graphite ferrule on the detector side of the capillary column as well. Since, normally, a locking nut is used, a cap nut need not be used ahead of the graphite ferrule (if analyses are conducted at column temperatures over 350 deg.C, it may be a good thing to reduce the thermal capacity by using a small cap nut in the same way as the entrance side). For the FID(FTD)
69mm (make it 2 to 3mm shorter if a metal capillary column is
used.) For the BID 74mm Remove the fixing jig once the position of the graphite ferrule is set. |

5 |
Pull the lever on the bottom right of the door towards you to open the column oven.
|
|
6 |
Hang the column on the column hanger. |
|
7 |
Insert the column into the sample injection port from the column oven side. |
|
8 |
After tightening the nut by hand, fix in place by turning the nut another half-turn using the wrench. |
|
9 |
In the same way, insert the column into the detector from the column oven side, and after turning the nut by hand to tighten it, fix it by tightening it about a half-turn further with the wrench. |
|
10 |
Close the column oven door and start up the system. |
