ELCD USERS - ATTENTION! To keep pace with Electrolytic Conductivity Detector (ELCD) technology, consider the newest design by O.I. Corporation's senior chemist, Dr. Randall Hall. Dr. Hall invented the first ELCD (which bears his name) in 1973, then in 1984, the O.I. Model 4420. After starting with patented new concepts in the 4420 cell and reactor design, he has continued to improve sensitivity, peak shape, and reliability with an intensive research program. The 4420 has been specifically engineered to interface with all major GC's. It can be installed in less than 30 minutes with proper fit assured. Capillary performance is unmatched, as is sensitivity. Your chromatography will never be limited by this detector, even in the most demanding applications involving detection of halogens, nitrogen, or sulfur. Get the benefit of state-of-the-art performance, continued development of new technology, and direct contact with the world's foremost expert on electrolytic conductivity detection. To find out how we can improve your results with our Model 4420, write or call for information today.
