SPECTROPHOTOMETRY AND ELECTRONIC CELL, GAS PRESSURE AND FLOW CONTROL METHOD

摘要

The gas flux controlling method is composed of (a) inputting a predetermined value of gas flux in a computer of an automatic control means; (b) supplying the previously set gas flux through a main gas supplying tube of a gas flow controlling means according to the input data; (c) detecting and adjusting the gas pressure discharged from a discharge cell of a glow discharging means. The gas pressure controlling method is composed of (a) inputting a predetermined value of gas pressure in the computer of the automatic control means; (b) supplying the previously set gas flux into an interior of the discharging cell through the main gas supplying tube of the gas flow controlling means according to the input data; (c) perceiving continuously the gas pressure of the interior of the discharging cell and adjusting gas flux through a subsidiary gas flux adjusting device of a subsidiary supplying tube.
