Need a hand ? Are you juggling ions from one piece of glassware to another— performing a ticklish, tedious round of distillations, extractions, and crystallizations?
Well, the AMBERLITE ion exchange resins won't make museum-pieces out of flasks, condensers, and funnels; but here are a few of the jobs that these synthetic adsorbents have done: • removed acids from reaction mixtures • separated hafnium from zirconium • separated uridine from a nucleoside solution the 17 steps previously used) • • • • • • • •
isolated vanillin from sulfite waste liquors removed argols from grape wastes recovered alkaloids purified organic nitriles prepared vanadium pentoxide sols hydrolyzed nitrite groups to amides aided in analysis of chromium compounds, aided in the fractionation of blood

Next time you say to yourself, "I need another pair of hands," investigate the AMBERLITE cation and anion exchange resins. Jot down your problem—concentration, isolation, or purification— and send it to Dept.CEI-5. Suggestions and literature (and samples, if you say so) that may help you save time and increase your yield will be in your laboratory in a few days.
