2.6 Chilled Mirror Dew Point Limitations
AquaLab limitation is its ability to accurately measure samples with
high concentrations (typically > 1%) of certain volatiles such as
ethanol or propylene glycol, which can condense on the surface of
the chilled mirror. The extent of the effect is determined by how
readily the material volatilizes, which is both concentration and ma-
trix dependent. Therefore, even if your sample contains materials
that could volatilize, it may still be possible to make accurate read-
ings using the chilled mirror dew point sensor.
AquaLab Series 4TEV which incorporates both a chilled mirror sen-
sor and a capacitance sensor for measuring volatile substances is
Decagon’s solution for products containing volatile materials. If you
are unsure if you need the TEV model, please call and discuss your
product with a Decagon Representative. Refer to the Chapter 8 sec-
tion titled “Volatile Samples” or contact Decagon for more details.
