Georges,
   Supelco will make the column as a custom column.  They were about $120 and were reasonable quick.  You can buy the packing from CRS as well

Subject: Re: [ISOGEOCHEM] TC/EA GC column molecular sieve

Hi Georges,

I replace my GC column on my TC/EA too.

The provider was RESTEK.(france)

The part Number PC 10751
Ref: MS-5A 80/100  .6m 5,4mmID  1/4 in OD

This replacement was successful, you must just adjust the He flow rate.
Because the molecular sieve packing depending of the provider.

Alexandre

> Does anyone know a good source for replacment molecular sieve 5a for the GC column in the Finnigan TC/EA?  Marilyn mentioned a while back that there was a Supelco kit for repacking the column, but I'm having a hard time finding it.  The Sigma Aldrich website has molesieve 5a packing in 60/80 mesh, but not 80/100 mesh.
