ICL
has brought back the 3M® card, which we manufacture
under a license from Minnesota Mining and Manufacturing
Company. PTFE and polyethylene IR sample cards provide
inexpensive disposable sample substrates for qualitative
analysis. The 2” x 4” cards mount vertically
in the universal slide mount in any spectrophotometer.
The cards have a clear aperture of 19mm and space is provided
to write on the card to identify the date of the analysis,
the sample and the name of the analyst. The cards are
sold in packages of 10, 25 and 50 and the polyethylene
cards are also available with two
sample substrates.
PTFE
and Polyethylene cards exhibit absorbance bands in the
4400 to 400 CM-1 spectral range. Absorbance spectra of
the cards are shown in Fig. 1 and Fig. 2 below. Real
Crystal® IR Sample Cards which do not exhibit
any absorbance peaks are also available.
