ISO 15680:2003规定了通过吹扫和捕集分离和气相色谱法（GC）测定水中挥发性有机化合物（VOCs）的一般方法。附录A、B和C提供了可使用ISO 15680:2003测定的分析物示例。其范围从二氟二氯甲烷（R-12）到三氯苯，包括所有具有中等挥发性的非极性有机化合物。 检测最好在电子碰撞模式（EI）下通过质谱进行，但也可以使用其他检测器。 检测极限在很大程度上取决于使用的探测器和操作参数。通常可以达到低至10纳克/升的检测限。工作范围通常高达每升100微克。 ISO 15680:2003适用于饮用水、地下水、地表水、海水和（稀释）废水。

ISO 15680:2003 specifies a general method for the determination of volatile organic compounds (VOCs) in water by purge-and-trap isolation and gas chromatography (GC). Annexes A, B and C provide examples of analytes that can be determined using ISO 15680:2003. They range from difluorodichloromethane (R-12) up to trichlorobenzene, including all non-polar organic compounds of intermediate volatility. Detection is preferably carried out by mass spectrometry in the electron impact mode (EI), but other detectors may be applied as well. The limit of detection largely depends on the detector in use and the operational parameters. Typically detection limits as low as 10 ng/l can be achieved. The working range typically is up to 100 micrograms per litre. ISO 15680:2003 is applicable to drinking water, ground water, surface water, seawater and to (diluted) waste water.
