水对非甲烷总烃（NMHCs）的测量可能产生以下影响：
湿度影响
高湿度环境下，空气中的水汽可能与非甲烷总烃发生溶解或吸附作用，导致气体浓度测量偏差。此外，湿度变化还可能影响仪器内部电子元件性能，降低测量精度。 ‌
水洗作用
在地质环境中，水洗作用可能优先带走低碳烃类物质，导致非甲烷总烃的组成和浓度发生变化。例如，原油中轻质烃类在地下水作用下易流失，影响油气藏的物性特征。 ‌
样品处理干扰
若非甲烷总烃样品需脱水处理（如使用干燥剂），未彻底去除水分可能导致后续检测中离子化反应异常，影响检测结果准确性。 ‌

The measurement of non methane total hydrocarbons (NMHCs) by water may have the following effects:
CHmin
In high humidity environments, water vapor in the air may dissolve or adsorb with non methane hydrocarbons, leading to measurement deviations in gas concentration. In addition, humidity changes may also affect the performance of electronic components inside the instrument, reducing measurement accuracy.  ‌
water washing
In geological environments, water washing may preferentially carry away low-carbon hydrocarbon substances, leading to changes in the composition and concentration of non methane total hydrocarbons. For example, light hydrocarbons in crude oil are easily lost under the action of groundwater, which affects the physical properties of oil and gas reservoirs.  ‌
Sample processing interference
If methane total hydrocarbon samples do not require dehydration treatment (such as using desiccants), incomplete removal of moisture may lead to abnormal ionization reactions in subsequent testing, affecting the accuracy of the test results.  ‌
