3.6.1 External pressure regulator installation
This optional accessory is used to regulate the pressure of the gas used for the syringe flushing
(e.g. Nitrogen).
The pressure regulator output must be set at 1 bar maximum (15psi or 100kPa). The external
pressure regulator is shown in the figure below:
Figure 75: External pressure regulator
The pressure regulator must be inserted between the gas source and the gas inlet of the
autosampler in order to regulate the inlet pressure.
In detail, the 1/8” tube coming out from the regulator (number 1 in the following figure) must be
connected to the gas inlet 1/8” located on the rear of the autosampler (number 8 in Figure 22).
