典型干扰现象
总烃浓度异常偏高：当进样空气或含氧废气时，总烃柱上会出现一个巨大的“氧峰”，导致总烃浓度远高于实际碳氢化合物浓度。
甲烷浓度虚高：在甲烷柱上，如果氧峰与甲烷峰分离不佳，定量结果会包含氧气贡献的信号。
非甲烷总烃为负值：当氧干扰导致总烃减去甲烷的结果小于零，即出现逻辑错误。

Typical interference phenomenon
Abnormal high total hydrocarbon concentration: When air or oxygen-containing exhaust gas is injected, a huge "oxygen peak" appears on the total hydrocarbon column, resulting in a total hydrocarbon concentration much higher than the actual hydrocarbon concentration.
Methane concentration is falsely high: On the methane column, if the separation between the oxygen peak and the methane peak is poor, the quantitative result will include a signal of oxygen contribution.
Non methane total hydrocarbons are negative: When oxygen interference causes the result of subtracting methane from total hydrocarbons to be less than zero, a logical error occurs.
