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


  • Determination of cadmium in biological samples by inductively coupled plasma atomic emission spectrometry after extraction with 1,5-bis(di-2-pyridylmethylene) thiocarbonohydrazide.: This study utilizes Isobutyl methyl ketone (IBMK) as a solvent in the extraction process for determining cadmium in biological samples. The research highlights the efficacy of IBMK in enhancing the sensitivity and accuracy of inductively coupled plasma atomic emission spectrometry (ICP-AES), crucial for trace metal analysis in various biological and environmental samples (Espinosa Almendro et al., 1992).

  • Colorimetric determination of acetylenic hypnotics by formation of silver acetylides.: This research demonstrates a colorimetric method for determining acetylenic hypnotics using Isobutyl methyl ketone (IBMK) as a solvent. IBMK is instrumental in the formation of silver acetylides, facilitating the detection and quantification of these compounds in pharmaceutical formulations. The study underscores the versatility of IBMK in analytical chemistry applications, particularly in the pharmaceutical industry (Rizk et al., 1980).
