is a fluorinated hydrocarbon solvent that is ideal for preparation
of samples to be run from 4000 to 1360 cm-1 where it is
non-absorbing, except at 2321.9 cm-1. This very high viscosity
liquid will make virtually any sample adhere to a crystal
substrate, making it ideal for preparing mulls with Real
Crystal IR cards or with water polished crystal blanks.
To prevent contamination, Fluorolube® comes in a convenient
size squeeze bottle, which contains enough solvent to produce
over 100 samples.
is a high purity mineral oil that is used for the preparation
of mull samples in the wavelength range of 1370 cm-1 to
the far infrared, with only one absorption band at 720 cm-1.
Nujol® is ideal for preparing mulls with Real Crystal
IR Cards or salt crystals.
