has brought back the 3M® card, which we manufacture
under a license from Minnesota Mining and Manufacturing
Company. Polyethylene IR sample cards provide inexpensive
disposable sample subsrates for qualitative analysis.
The 2" x 4" cards mount vertically in the universal
slide mount in any spectrophotometer. The cards have two
clear apertures 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 are also available with
one sample substrate.
cards exhibit absorbance bands in the 4400 to 400 CM-1
spectral range. Absorbance spectrum of the cards is shown
in Fig. 1 below. Real Crystal®
IR Sample Cards which do not exhibit any absorbance peaks
are also available.
