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.

N/A 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. Real Crystal® IR Sample Cards which do not exhibit any absorbance peaks are also available. |
