Well, the killer problem is with Pro-Met-Val. Once you loose that
separation, kiss
the column goodbye. I never saw problems with Ser-Gln-Thr. I use a
Beckman micro-
PTH column. Good luck. Regards. Tom

I read recently about the problems a few people were experiencing with PTH
columns for the Procise. I too have been waiting for a couple of months for
a new column that I ordered. I did receive a PTH column but sent it back
just before they went onto backorder because the resolution between Q/T and
K/L didn't look right. I did manage to get another column sent and it too
gives a similar profile. The Q/T separation is not great. Is it true that
if
a column is on its way out then the resolution between Q/T and K/L are the
first ones to go ? Again, any views or updates would be appreciated.
