Surveyor Plus Refractive Index and Surveyor Plus Fluorescence detectors enhance analytical capabilities when integrated with the Finnigan Surveyor Plus HPLC product line (Thermo Electron Corp.). The fluorescence detector monitors the emissions of fluorescence, phosphorescence and chemiluminescence, and also analyzes polyaromatic hydrocarbons (PAHs), derivatized amino acids, carbamates and glyphosates. The refractive index detector is suitable for detecting compounds lacking chromaphores such as alcohols, fatty acids and esters. Thermo Electron Corp.800-532-4752www.thermo.com/lc
