The analysis of volatile components in urine samples using INCAT device

摘要

Work was focused on the development of INCAT, a solventless microextraction technique with adsorbents inside a steel needle. The device was used for the extraction and preconcentration of volatile compounds, and subsequently analyzed by gas chromatographic methods. The sorption characteristics of INCAT devices with different sorbents were compared, and the device with sorbents Chromosorb W + 20 % SE-54, Carbopack X, and Carboxen 1000 (in 1:1:1 v/v ratio) was applied for the analysis of volatile organic compounds in urine samples of patients with metabolic diseases.
