that can arise when using the unit.
Personnel without such training or persons currently under-
going a course of training should be trained thoroughly. This
Instruction Manual should be the basis for this training.
2.3
Proper use
The unit is designed and built for use in laboratories. It is intended
to be used for determining the fat content based on fatty
acids or the butyric acid. Its function depends on the Büchi
Extraction Unit B-815: Some microliters of the upper extracted
phase which contains the fatty acids and the internal standard
are injected either manually into the Fat Determination Unit
B-820, or automatically into the Fat Determination Unit with
Autosampler B-821. The detection occurs with a flame
ionization detector (FID). The subsequent evaluation is made
by integrating the total peak areas.
Only original Büchi replacement parts and accessories may
be used. Any modifications to the device or accessories shall
be permitted only upon consultation with and obtaining a
written authorization from the manufacturer.
