アプリケーション

• Toluene Detection in Biological Samples Using SPME-GC-MS.: This research presents a method for detecting toluene in biological samples using solid-phase microextraction combined with gas chromatography-mass spectrometry (SPME-GC-MS). The method provides high sensitivity and accuracy, making it suitable for biological monitoring of toluene exposure (Suh et al., 2015).


• Adsorption Characteristics of Toluene on Metal-Organic Frameworks.: This paper explores the adsorption characteristics of toluene on various metal-organic frameworks (MOFs). The study identifies the most efficient MOFs for toluene adsorption, offering insights for industrial applications in air purification (Zhang et al., 2019).
