Hey Steve...

The ceramic tubes that Thermo are selling are thicker walled these days.  Try the IVA...they still have the original thinner walled ceramics.

Hello all,

A question for TCEA users.

The ceramic tubes I've been buying have an I.D. of ~12.8mm. The glassy carbon tubes I use have an O.D. of ~12mm. This doesn't leave much room for the helium flush.

I recall discussing this with someone at the CF-IRMS conference in New Brunswick, who had found a supplier of thinner walled ceramic tubes (but with the same O.D.) ... but I can't recall who that person was ...

Anyone out there found a suitable thinner walled ceramic tube?

Thanks,
Steve
