Analysis of highly polar compound (ionic liquid) by DART
Introduction
Direct analysis in real time (DART™) is applicable to a wide variety of samples; from low polar to highly polar compounds.
Ionic liquids have drawn much attention from various engineering fields, such as tribology, because of their unique properties of electrical conductivity, extremely low vapor pressure, low viscosity, low combustibility, etc. The sample was analyzed by dipping a glass rod to the sample and presented it directly to the DART™ ion source.
