The influence of interfering substances on breath-alcohol measurements is handled by the OIML by giving a list of test gases and prescribing the maximum permissible cross-sensitivity of a measuring system. The expertise of the Federal Health Office for evidential breath analysers prefers an other way to detect interfering substances in expired air. By the use of two measuring systems with different analytical specificity interfering substances as e.g. methanol, isopropanol, aceton, ethylacetat, and toluene cause measured values with a difference which exceeds the limits permitted in the OIML recommendations. The same happens with interfering substances in expired air which are most commonly used by sniffers as e.g. Pattex, Uhu adhesive, or petrol.
国际法制计量组织（OIML）通过给出测试气体列表并规定测量系统的最大允许交叉灵敏度，来处理干扰物质对呼气酒精测量的影响。联邦卫生局对用于证据目的的呼气分析仪的专业意见倾向于采用另一种方法来检测呼出气体中的干扰物质。通过使用两个具有不同分析特异性的测量系统，甲醇、异丙醇、丙酮、乙酸乙酯和甲苯等干扰物质会导致测量值出现超出OIML建议允许范围的差异。呼出气体中那些嗅吸者常用的干扰物质，如百得胶、优力胶粘合剂或汽油，也会出现同样的情况。
