Re: CO reference for TC/EA
Dear Drew and others,

It appears we are all in the same boat, and some companies are trying to get European CO for us (MG Industries), but this taking some time.  We are also taking delivery of a TC/EA soon, and I have asked several times to the isotope community if anyone has any ideas about how to approach this problem.  Bill Showers is also a good person to contact.  Do not order any US-CO.  We did and made the $850-mistake, with a high purity tank and a delta of about -350 per mil.  You are better off using your own internal standards than a ref. gas with such a negative value.

-Bill
