General description

EMSURE grade solvents are suitable for a broad spectrum of classical lab applications, and are frequently used in regulated and highly demanding lab applications. EMSURE provides worldwide best and most extensive product specifications. We declare our EMSURE range to be in compliance with the ACS, with the reagent part of the European Pharmacopoeia (Reag. Ph Eur) and also with the ISO standards.

Application


  • 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).
