Short-chain fatty acids (SCFAs) are very volatile compounds and choosing an appropriate isolation and enrichement technique is a key to their determination. Distillation is one of methods which can be applied. There are many types of distillation. The simplest ones are direct, steam and fractional distillation, but they are not used very often and have some drawbacks. However, many modifications of basic distillation have been developed and applied. A few techniques, such as simultaneous distillation-extraction (SDE), headspace co-distillation (HCD), stir bar sorptive extraction (SBSE) and nitrogen purge and steam distillation (NPSD), can provide specific conditions depending on what is to be achieved in determination of SCFAs. The main adventage of distillation is its application, not only for water samples but also for solids. In final determination, gas chromatography is a method of choice, mostly because of its sensitivity, accuracy and possibility of determination of single acid.
