Abstract: PURPOSE:To obtain a self-excitation type fluorescent lamp lighting device having simple light control operation and high safety by sending a clock pulse to a rekeyed counter via a touch switch, changing a brightness of the fluorescent lamp and installing a no-load generation and oscillation stopping device so as to prevent an electric shock. CONSTITUTION:One clock pulse is output from a clock pulse generating circuit 16 to a rekeyed counter 17 per touch to a switch 15. A terminal P0 turns to 'L' and a terminal P1 turns to 'H', and a contact S1 of a relay RY1 is closed to make an inverter 8 to oscillate. A contact S2 is closed to light a fluorescent lamp 9 in full light. With next touch, a terminal P2 turns to 'H', a contact S2 of a relay RY2 is open to make a brightness lower by one step which depends on a capacity C1, and a contact S4 is closed to make LED to display a light control step lamp. With further one touch, the counter 17 is reset. At the time of no-load, a preheating circuit 13 is open and a transistor Q5 takes off. The charge of a capacity C4 in a time constant circuit 21 is started and at the predetermined value, the counter is reset. The relay RY1 takes off so as to stop the inverter 8 without danger of electric shock. Restarting is secure by discharging of the capacity C4 after stopping of oscillation.

     CONSTITUTION: A bypass valve 16 is arranged as close to a quantitizing valve 7 as possible, and their relative positions are set such that a sample conduit 8 has its length (or volume) minimized. A sample is always returned through the bypass valve 16, a needle valve 19, a flow meter 20 and a bypass conduit 21 to a sample return outlet 15. Under this particular condition, the sample does not flow into the quantitizing valve 7 so that it is not released to the atmosphere. Safe gases such as N 2  are fed to a purge gas inlet conduit 17 and are discharged to the atmosphere from a sample outlet 12 through the bypass valve 16, the quantitizing valve 7 and a quantitizer 8. In the case of quantitizing the sample, the bypass valve is operated, and the passage in the valve has communication at its broken line portion so that the sample flows through the conduit 18 into the valve 7 and the quantitizer 8. After this quantitizer 8 is substituted with the sample gases, the valve 7 is operated to inject the quantitized sample into the column.
