General description

4-Methyl-2-pentanone also known as MIBK, is widely used in analytical chemistry as a solvent due to its excellent volatility, low water solubility, and compatibility with both polar and non-polar analytes. In chromatography, MIBK is particularly valued for its role in gas chromatography (GC) and sample preparation workflows, where it enhances analyte recovery and resolution in complex matrices.

Application

  • MIBK is used as a solvent and diluent in GC analysis of volatile organic compounds (VOCs), hydrocarbons, and environmental pollutants.
  • MIBK has well-characterized retention indices and vapor-phase behavior, making it suitable for use in GC method development and calibration

    C of A's for EMD chemicals

    What happened to the C of A's that had actual Lot results in them? The C of A now is more like a product spec sheet, not a real C of A. I'm not pleased!
