Celebrating 20 Years of HPLC-CAD Technology
Author(s)Thermo Fisher Scientific
The first charged aerosol detector (CAD) was introduced in 2005. Nearly twenty years later, this near-universal detector has become an indispensable tool in the analytical chemist’s quantitative arsenal. This paper explores the CAD’s origin story, its adoption into everyday use by separation scientists, and its comparison to evaporative light scattering detector (ELSD). Technical highlights will include how parameters such as evaporation temperature influence application versatility, and how the power function impacts linearity and response behavior.
