This ECO Funnel® has been modified to accept 3/4" hosing from LCMS outlets, trapping any droplets of liquid in the ECO Funnel® and then venting the residual fumes to a ventilation hood. Two hoses, from the MS unit and an ELSD unit, have both droplets as well as fumes from acetonitrile and trifluoroacetic acid. A third hose connects to the ventilation hood.
