OTHER DETECTORS
Some compounds are simply not UV active and require a different type of detector. Bay Scientific recommends the Knauer Refractive Index Detector as a universal detector for Isocratic HPLC applications.

For compounds such as anions, cations, metals, organic acids and surfactants, we recommend the Model 550 Conductivity Detector. It can turn any HPLC into an Ion Chromatograph. The Model 550 can be used with a single column or with a suppressor based system and can quantitate samples in the ppb (parts per billion) range.
