Introducing the NEW 1977Basic™Gas Chromatographs ...now Carle puts a low price on the answer APPLICATION ENGINEERED B G C s α • α • • • • π ο π • Q • • •
The Basic Gas Chromatographs have been around a long time. There are plenty of good reasons why, things like de pendability and offering the most GC value for the fewest dollars. Now a new generation of BGCs have been given a new dimension: each model is factory-dedicated to perform a specific analysis. You can select a new BGC to perform one of fifteen different analyses, accomplished by either a dedicated GC 8700 (thermal conductivity detector) or a dedicated GC 9700 (flame ionization detector). Each model has the proper columns to do the job, proven in the Carle applications laboratory, plus built-in gas sampling and column switching valves

where applicable. Nothing else is required but your sample. Factory-dedication to specific problem solving is the biggest change in the 1977 Basic Gas Chromatograph, but there have been numerous engineering changes too, like in corporating Carle Mini Volume Val ves.The results are new standards for ease of operation and compact mobility, along with the proven BGC performance. To learn the complete technical story, call or write for your copy of the new full-color 8-page technical bulletin describing Carle's 1977 Basic Gas Chromatographs. Also available on request are individual Application Data Sheets detailing results for each of the 15 different analyses.
