Restek training seminars
are full-day courses presented in
an engaging multimedia format. They are equally valuable
to beginning chromatographers, those who have moderate
experience and want a better understanding of the subject
matter, and those interested in the “best practices” and
latest technologies.
No sales pitch is presented
, just the
facts on how to make your chromatography results better.
