Hi everyone,

I hope all is well with you.

In this lab there is a Carlo Erba EA1106 elemental analyzer which is 
presently unused because it is designed to accept only the very narrow 1 cm 
diameter combustion tube. Our lab processes large numbers of samples for 
d15N and d13C analysis so for this reason the very narrow combustion tube 
is not practical. 

However, I noticed that the diameter of the interior of the furnaces inside 
the EA1106 are large enough such that a full sized 2 cm diameter combustion 
tube will fit inside. 

I'm thinking that if I replace the fittings on the top panel of the EA1106 
with suitable fittings which enable a full sized autosampler to connect to 
a full sized 2 cm diameter combustion tube, the EA1106 could then be made 
into an improved capacity sample preparation unit for isotope analysis.

Do you know of a case in which this modification was successfully done? Do 
you know of any fundamental reason why this modification of an EA1106 to 
accept a full sized 2 cm diameter combustion tube will not work? If so 
please let me know.

Thank you,
