Hi Dachun,

At times these parts can be considered as a consumable. What helps is by reducing the ice build up on the top of the trap.  By mounting a small 12V fan blowing towards it and insulating the cables with heat shrink and LN2 tubing going into the trap cascade, this has considerably reduced our consumables.

Best regards

Stewart

Betreff: [ISOGEOCHEM] Frequently broken heater and thermocouple of Kiel

Dear Colleagues:

Both the new heating cartridge and measuring resistor in our Kiel device
trap 1 are broken (not the same time) in less than two month. It
happened twice already. Any suggestions would be appreciated.

Thanks.
