6.2 Analytical problems
Analytical problems such as poor reproducibility and carry-over can occur in
any chromatography system. The cause is usually difficult to find. First of all,
you should attempt to determine whether the problem is caused by the
Autosampler or another component of the system.
Please take into consideration the fact that analytical problems can also be
caused by external influences such as temperature or light-sensitive sample.
Make sure that the application was able to be performed previously without
problems and that no changes have been made to the system.
Some causes and possible solutions for analytical problems are listed below.
Contact your service point for additional help.
6.2.1 Autosampler
Problem Cause Remedy
The reproducibility
does not correspond to
the specifications. There is air in the flow path. Carry out a standard washing procedure
(in MagIC Net
™
under Manual con-
trol ).
