Field and Laboratory

Publication Date



This article suggests a paper chromatographic separation of the dyes in commercial black inks, which has been designed for completion in one 3-hour laboratory period with the use of equipment and solvents found in practically all laboratories. The experiment gives very satisfactory results, and allows the student to become familiar with the general field of paper chromatography and some of the factors which affect Rf values of constituents of mixtures. It also may be used to demonstrate the use of simple statistical tests, if desired.
