The analysis of volatile organic compounds (VOCs) emitted from biological fluids such as
blood, urine, breath and faeces, has been receiving more attention from researchers and …

In this chapter, we describe the procedure for metabolic profiling of hundreds of urinary
volatile organic compounds (VOCs) using headspace solid-phase microextraction (SPME) …

The diagnostic potential and health implications of volatile organic compounds (VOCs)
present in human feces has begun to receive considerable attention. Headspace solid …

Abstract Background Volatile organic compounds (VOCs) can be intermediates of metabolic
pathways and their levels in biological samples may provide a better understanding about …

Recent studies have illustrated the importance of the microbiota in maintaining a healthy
