General
Since its introduction into the market in
1996 YMC*Gel Pro C18 has proved to
be one of the first choices for a wide
range of HPLC applications in pharmaceutical
and biotechnological research
and production, where efficiency and
reliability are of the highest importance.
The main reasons for this success include the excellent performance in
HPLC separations and the high lot-to-lot
and column-to-column reproducibility
which are essential for chromatography
in general. The achievement of this superior
performance is not as trivial as
first impressions might give. To ensure
high quality continuously, a consistent
and stringent quality control system is required.
The figure below demonstrates
the high lot-to-lot reproducibility
for three lots selected at random.
