Permeation of methomyl in Lannate L~TM through nitrile gloves

摘要

The influence of the inert components on the permeation of methomyl in Lannate L water miscible pesticide formulation through 0.64 mm thick unsupported lined nitrile at 30 deg. C was assessed using an ASTM-tupe permeation cell with isopropanol liquid collection medium. Gas chromatograpy/mass spectrometric (GC/MS) analysis of 0.100 ml aliquots of the collection fluid taken every 10 min revealed that the breakthrough time for permeation of emthomyl was > 200 min with a steady state permeation rate of 5.24 ± 1.00 μg cm~-2 min~-1.
