| titleOfInvention | Method for detecting exhaled breath acetone on line |
| abstract | The invention discloses a method for detecting exhaled breath acetone on line, which adopts a pretreatment method of on-line semiconductor refrigeration dehumidification, effectively eliminates the interference of humidity in exhaled breath on the detection of acetone by photoionization ion mobility spectrometry, and improves the sensitivity of the detection of exhaled breath acetone by photoionization ion mobility spectrometry. The method comprises the following specific steps: preparing relative humidity 100% RH acetone standard gas, sequentially introducing into a semiconductor refrigerating device for online dehumidification, and then continuously sampling by a sampling pump for detection to obtain a standard curve of 100% RH acetone; introducing the sample into a semiconductor refrigerating device for online dehumidification, and then detecting by photoionization to obtain an ion mobility spectrum spectrogram of the exhaled breath sample to be detected; and comparing the ion mobility spectrometry spectrogram to calculate the actual concentration of the acetone in the exhaled breath sample to be detected. The method can provide a rapid, noninvasive and accurate method for effectively screening and diagnosing the diabetic patients through the detected acetone concentration in the exhaled breath. |
