electrochemical detectors for liquid chromatography In 1974 BAS introduced the first commercial LCEC system. With over 5 0 0 0 units installed and the largest research team to support them, it's not surprising that our nearest competitors are several generations behind us. Our thin-layer transducers lead the w a y with ο wide selection of electrode materials in a variety of interchangeable configurations. The latest members of the family are revealed in the new LC4B/17 dual electrode amperometry package. Parallel and series amperometry can enhance selectivity, detection limits, speed and gradient compatibility. Let us show you how it's done, no one else can. Write or call for a detailed assessment of your trace analysis problem.
