We are getting poor 18O peak shape which we think is possibly due to
memory effects from the GC column.
We are looking to replace this which is a Chrompack packed column to
replace one in our Thermo TC/EA system connected to a Delta XP. The
label says Column No. TN 1403 which is 0.6M x 1/4" x 4mm ID S/S
packed with molecular sieve 5A 80-100 mesh.
I cannot seem to find a Chrompack distributor who still deals in
packed columns. Does anyone know of an equivalent?
