NIST traceable Polystyrene Test film, certificate of traceability to five (5) NIST 1921b frequencies, set of 2 films each mounted to 2” x 4” cardstock holder Also available with PhEur 2.2.24 certified polystyrene calibration film (inquire for quote). Includes instructions for two (2) film ordinate calibration and storage case. Both films are mounted on 2″ x 3″ cardstock holder with a 19mm aperture for mounting in the universal slide holder in all instruments. The second film is 76 microns and is provided without certification. One film is 38 microns and is provided with certification of traceability to five (5) NIST 1921b frequencies. Pair of polystyrene calibration films of different thickness. To learn more, visit our catalog for FTIR calibration films today. PhEur 2.2.24 films are described in a separate section.
#Polystyrene on crystal maker windows#
These windows can be matched in pairs with comparable absorbances. Boron doped crystal windows are also available as calibration standards. The polystyrene coating prevents degradation of the KBr window from moisture effects. KBrwindows with films are sold with a mount with a 2” x 3” backplate that fits the standard universal slide mount in all spectrophotometers. Films cast on KBr windows will not exhibit any interference fringes.
#Polystyrene on crystal maker free#
Films are available in free standing pairs mounted on 2” x 4” cards that fit in the standard universal slide mount in all spectrophotometers or the films can be cast on KBr windows. Sold in pairs of two (2) different film thickness, the differential between the absorbance intensities created by the two (2) film thickness becomes the baseline, thereby making the pair of films suitable both as an ordinate calibration standard useful for detection of degradation in instrument performance and for calibrating the abscissa scale in accordance with NIST Standard 1921. This makes the films consistent from film to film. Superior calibrations are performed with radially symmetric films which eliminate the orientation effects of extruded films used for NIST Standard 1921 calibrations. In addition to standard polystyrene calibration films, ICL offers several other calibration options.
