Abstract: A piece of fused-silica fibre coated with silica modified with ketamine-groups was used as a solidphase microextraction (SPME) fibre and its efficiency in the qualitative and quantitative analysis of volatile organic compounds released from coloured overprinting on DVDs was evaluated. The effect of the parameters that can affect the SPME procedure, such as extraction time, extraction temperature, desorption temperature, was investigated to determine the analytical performance of this novel fibre in the qualitative and quantitative analyses of organic compounds. The optimised procedure was applied to the qualitative and quantitative analyses of organic compounds released from coloured overprinting on DVDs. The limit of detection of 4-methoxyphenol (mequinol) was 88 × 10⁻³ μg mL⁻¹, while the limit of quantification (LOQ) was calculated as ten times the baseline noise, i.e. 3.1 × 10⁻¹ μg mL⁻¹. The proposed fibre was used successfully for preconcentration of the volatile organic compounds from the gaseous phase of DVD samples.
