Abstract
1446085 Ionization detectors R KAISER 21 Nov 1973 [21 Nov 1972] 54124/73 Heading H1D A flame ionisation detector, for detecting the presence or absence of either hydrocarbons or hetero-compounds (by which is meant organic compounds containing inorganic atoms such as P, N or S.) comprises a chamber 1, a duet 4 having an outlet in the chamber directed towards a collector electrode 3 for carrying a first combustion flame during use of the detector in the detection of hydrocarbons. A second duct 8 is angled with respect to the duct 4 and has an outlet in the chamber directed generally towards the outlet of duct 4 and away from electrode 3 for carrying a second combustion flame during the use of the detector in the detection of hetero-compounds. A carrier 5 supports a salt 7 in the path of the second flame but not in the path of the first flame. The electrode 3 is frusto-conical and positioned in the chamber for collecting ions. To detect hetero-compounds, H is supplied to duct 8 and ignited at the outlet, so that the tip of the flame is in contact with a salt 7 appropriate to the compound being detected in the cup 6 of a salt-carrier 5. The sample is supplied to duet 4. Duct 8 is connected to a potential of - 200v. to - 300v, carrier 5 to earth or a positive potential and duct 4 to a potential of 0v. to + 300v. Carrier 5 is adjustable parallel to the axis of duct 8. To detect a hydrocarbon, the sample is mixed with combustion gas, supplied to duct 4 and burnt at the outlet. No gas is supplied to duct 8. Duct 4, duct 8 and the salt carrier 5 are all connected to a negative potential. In either case, ion current to electrode 3 increases in the presence of the compounds to be detected, and this current is amplified by an amplifier 12 and recorded by a recorder 13.
