A CHIRALPAK IG column (immobilized meta selector) was used to develop the enantioselective separation of methylclothiazide. Meta-substituted immobilized chiral selectors have been shown to have remarkable affinity for resolution of chiral compounds from different types of molecules. Available in 3 and 5 micron.

exposure to MOHs (Mineral Oil Hydrocarbons) via packaging could contribute significantly to the total exposure to these contaminants and may pose a human health hazard. In the present work, migration of MOHs and DIPN from recycled paperboard boxes in direct contact with dry pasta (both semolina and egg pasta) has been monitored during shelf life at regular times (up to two years).
