sampler, for example: oven 150

, and detector 180

.
6)
After the temperature of the sampler, detector (FID) and oven are in equilibrium, turn on the air and hydrogen gas
source. Adjust the air needle valve on the air panel and two hydrogen needle valve knobs to the appropriate flow
rate, according to the required operating conditions. (The flow rate will display on the screen.)
7)
Ignition: Press the two ignition buttons (FID A and FID B) on the FID amplifier panel, and the stylus will deviate
from the original position after the flame is ignited. There are two common methods to determine whether a fire
ignites:
a)
Press the ignition box on the screen detector dialog box to see the signal change, and thenthe ignition is
successful.
b)
A metal or glass sheet with a clean surface is placed in the "vent" of the ion chamber. If the surface of the metal
body or glass sheet is condensed by water vapor, the fire has ignited.
Note: To make it simple, the back-end equipment only uses a recorder as an example. If you are using a
chromatographic data processor or a chromatographic workstation, refer to the specific operating instructions,
including the operation of necessary signal attenuation.
