Author Stephen Ball Agilent Technologies, Inc. Craven Arms, UK High sensitivity analysis of phthalates using HPLC with low temperature evaporative light scattering detection Application Note Specialty chemicals, consumer products Abstract This Application Note describes how the Agilent 385-ELSD Evaporative Light Scattering Detector can successfully detect highly volatile dialkyl phthalates at very low concentrations. Dialkyl phthalates are a class of widely used industrial compounds selected for their many benefi cial chemical properties. Because of their high volatility, dialkyl phthalates have always presented a challenge for evaporative light scattering detection after separation by HPLC. The 385-ELSD has a built-in Peltier cooler and unique gas control to evaporate high boiling solvents at very low temperatures, making it ideal for detection of highly volatile dialkyl phthalates.
