After sniffing of glue solvents (mixture of aliphatic hydrocarbons: boiling fraction 60-90 degrees C, ethylacetate and toluene) a blood alcohol concentration of 1.96 permille was indicated with an instrument using the infrared wavelength of 3.4 micrometer for the spectrophotometrical determination of breath alcohol. Testing of the individual solvents with a simple manual procedure showed linear relationships between concentrations in breathing air and the false positive breath alcohol values. Aliphatic hydrocarbons predominantly are responsible for the false positive breath alcohol determination. With 500 micrograms/liter a value of nearly 1.5 permille can be produced (using the factor of 2100 for the calculation of the blood alcohol concentration from breath alcohol). With ethylacetate or toluene up to 1 milligram/liter 0.5 permille ethanol in the blood will erroneously be found. The problem of recognition of crossreactive other gases by the measurement at two wavelengths (3.4 and 9.2 micrometer) is discussed.
在吸入胶水溶剂（脂肪烃混合物：沸点范围为60 - 90摄氏度、乙酸乙酯和甲苯）后，使用波长为3.4微米的红外光进行分光光度法测定呼气酒精含量的仪器显示血液酒精浓度为1.96‰。采用简单的手动程序对各个溶剂进行测试，结果表明呼吸空气中的浓度与呼气酒精假阳性值之间呈线性关系。脂肪烃是导致呼气酒精假阳性测定的主要原因。当浓度为500微克/升时，可产生近1.5‰的值（使用2100的系数从呼气酒精计算血液酒精浓度）。当乙酸乙酯或甲苯浓度高达1毫克/升时，会错误地检测出血液中含有0.5‰的乙醇。文中还讨论了通过在两个波长（3.4和9.2微米）进行测量来识别交叉反应性其他气体的问题。
