Answer:It is a cation suppressor used in compatible ion chromatography methods with suppressed conductivity detection.
Answer:This configuration is the 2 mm CDRS 600 cation suppressor with reduced internal volume for appropriate narrow-bore IC systems.
Answer:No. CDRS is the cation suppressor configuration; ADRS is used for compatible anion suppression methods.
The Thermo Scientific Dionex CDRS 600 is a 2 mm cation dynamically regenerated suppressor for compatible suppressed-conductivity ion chromatography methods. Its purpose is to lower the conductivity contribution of the acidic mobile phase while supporting sensitive conductivity measurement of separated cations. The 2 mm format has reduced internal volume for narrower-bore chromatographic configurations and should not be substituted directly for a 4 mm suppressor without reviewing the separation method and fluidic requirements. The CDRS 600 is a cation suppressor, not the ADRS anion version or an ion-exchange analytical column. Installation requires the appropriate eluent, regenerant arrangement and electrical connections for the specific IC system. Follow the suppressor conditioning and operating procedure, then verify background conductivity, baseline noise and the response of known cation standards. Protect the membrane assembly from particles, unsuitable chemistry and prolonged operation outside the specified flow and current conditions. Compatible methods may include determination of inorganic cations using methanesulfonic acid eluents.
