A cool way to separate biological compounds is being developed by Japanese researchers. A stationary phase made of ice and water has been used to separate estrogen, amino acid derivatives and poly(oxyethylene) oligomers. Yuiko Tasaki and Tetsuo Okada from the Department of Chemistry at the Tokyo Institute used this phase to achieve a much larger theoretical plate number [(N) = 1,500] than previous ice experiments [N = 250] which allowed these applications.1 This novel stationary phase could be used to provide better separation selectivity for polar groups than silica gel, Okada told LCGC Europe.

Standard HPLC is often performed with mixtures of organic solvents and buffers. Methods have been defined and accepted for several years. A large number of separation methods run with high concentrations of organic solvents depending on the type of stationary phase with more or less environmental hazardous chemicals.
