Turn off the high pressure valve of each steel cylinder. At this time, the low pressure indication value on the pressure

3.5 Installation of Packed Column
For the on-column injection, the side of the injection inlet should be allowed for a section of empty column (at least
50mm), in order to facilitate the needle of the sampler to be fully inserted into the gasifier during injection.
Due to the rigidity of the column, φ5.7mm glass packed column must
be installed on the side of the injection inlet and
the detector inlet as well. For both side, the installation procedure is the same.
