J.T. Baker Research Products can supply all the appropriate materials you need for chroma tographic chiral separations. B A K E R B O N D ™ Chiral Phase HPLC Columns use high purity DNBPG ((B)-N-3,5-dinitrobenzoylphenylglycine) bonded to aminopropyl silica to separate a wide range of optical isomers. Up to 10 mg of sample can be ap plied to the column in a single injection. Preparative chiral sorbents. in 40 urn particle size, are also available for scale-up of separa tions. In addition, longer column life can be achieved with our Chiral Column Regenerating Solution. For more information, call or write today. J.T.

Model 8300 Gas Chromatograph incorporates built-in data handling with a 12-in. video display and postrun manipulation of data. Two versions are available—one for packed-column operation and one for dedicated capillary systems. Easy interchange between injector and detector types permits analysis of a wide range of samples. Perkin-Elmer 402
Organic Vapor Monitor/GC Model 590 contains both a continuous organic vapor monitor and a gas chro matographic system in one compact portable unit. It allows an operator to survey an area for high concentrations of organic vapors and quantitate them on site. With a PID, the instrument can detect 5 ppb benzene and can operate for 8 h without an external power source. Analytical Instrument Devel opment 405
Polarographic Analyzer/Stripping Voltammeter System Model 264A-1 makes automated po larographic and stripping voltammetric measurements and can perform cyclic voltammetry. It features microproces sor control to automate measurement sequences and perform self-diagnostics and includes a newly designed elec trode system that can be converted to an electrochemical HPLC detector.
