What is DILC​TM

Direct Inject Liquid Chromatography (DILCTM) is a hardware and software ecosystem that enables direct sampling and analysis of chemical reactions. The system consistently samples your reaction vessel and delivers aliquots to an external liquid chromatography instrument for real-time analysis.

DILCTM enables unattended sample capture, quenching, dilution, and analysis using a variety of industry standard CDS platforms including Agilent OpenLab, Agilent ChemStation, Waters Empower 3, and Shimadzu LabSolutions.

DILCTM is the only tool that works together with Mettler Toledo iC LC software for sample scheduling and data acquisition.
