  • Patent number: 10161906
    Abstract: To widen the dynamic range of a dielectric barrier ionization detector (BID), an insertion length of a sample injection tube 16 into a second gas passage 11 is set so that a sample-gas ejection port 16a is located on the downstream side of a dilution gas from the upper edge of a collector electrode 14 at which a DC electric field concentrates. By this setting, although the detection sensitivity is lower than in the case where the sample-gas ejection port 16a is placed to maximize the detection sensitivity, the decrease in the detection sensitivity to high-concentration samples is reduced since absorption of light by the sample gas is alleviated. Consequently, the sample-concentration range with a linearly-changing sensitivity becomes wider than that of conventional BIDs. Although the detection sensitivity becomes lower than that of conventional BIDs, a detection sensitivity adequately higher than that of FIDs can be ensured.

  • Patent number: 10114059
    Abstract: In the present invention, the connection between an external power supply and a unit for detecting welding of a relay is disestablished at least when a short circuit is detected, thereby preventing the short circuit from being falsely detected in the event that the short circuit and the welding of the relay can both be detected. A device for detecting welding of a relay detects welding of a relay provided to a path via which a cell is charged by an external power supply. Welding of a power-supply-side relay or a ground-side relay is detected on the basis of a current flowing disproportionately more toward the external power supply than the power-supply-side relay or ground-side relay when a control unit has deactivated the power-supply-side relay or ground-side relay during an interrupting in charging. A disconnecting switch establishes or disestablishes the connection between the external power supply and a weld-detection switch.
