The application multiparameter-measurements-of-eliquids explains the setup of a multiparameter system that simultaneously determines density, refractive index, pH and UV/VIS color in multi component samples like E-liquids. Samples of different nature, given by the presence or absence of nicotine as well as different flavors are easily characterized with this configuration.
Background:
E-liquid refers to a liquid solution typically used in e-vapor products such as e-cigarettes. Together with flavoring agents and nicotine, they are mostly composed of vegetable glycerine (VG) and propylene glycol (PG).
Determination of density and the specific gravity of e-liquids are important quality indicators and are used in routine analysis. Together with these properties, pH and color determinations can be performed with a complete METTLER TOLEDO multiparameter system containing an Excellence Density Meter, Excellence Refractometer, Spectrophotometer and SevenCompact pH/Ion Meter.
The multiparameter system fully automates your processes and determines all parameters in a single procedure, either as standalone setup or connected to LabX® PC Software.
