■ Radially Symmetric Polystyrene Calibration Films & Calibration FilmsCast On KBr Windows

(미국 특허 제 6,254,931 호 )



■ Boron Doped KBr Calibration Windows (U.S. Patent No. 6,594,008)



■ PhEur 2.2.24 Calibration Standards



■ ICL (International Crystal Laboratoy)

In addition to standard polystyrene calibration films, ICL offers several other calibration options.

Superior calibrations are performed with radially symmetric films which eliminate the orientation effects of extruded films used for NIST Standard 1921 calibrations.



This makes the films consistent from film to film. 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.



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.

Films cast on KBr windows will not exhibit any interference fringes.

KBr windows with films are sold with a mount with a 2” x 3” backplate that fits the standard universal slide mount in all spectrophotometers.

The polystyrene coating prevents degradation of the KBr window from moisture effects. Boron doped crystal windows are also available as calibration standards.

These windows can be matched in pairs with comparable absorbances. PhEur 2.2.24 films are described in a separate section.

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





Pair of polystyrene films of different thickness, both with NIST traceability certification. Kit also includes a pair of standard polystyrene films, but without NIST traceability certification.



One NIST traceable film is mounted on 2" x 4" cardstock, which enables mounting in the standard universal slide mount found in all spectrophotometers, and is the same thickness as an NIST 1921 standard film (38 microns).



The second thinner NIST traceable film is cast on KBr and includes holder and mounting device.



Kit includes certification of traceability to five (5) NIST 1921b frequencies, radial symmetry certification for film cast on KBr and storage cases for all films.
