Radially Symmetric Polystyrene Calibration Films & Calibration
Films Cast On KBr Windows
( U.S. Patent No. 6,254,931-- Other Patents Pending)
Boron Doped KBr Calibration Windows
(U.S. Patent No. 6,594,008)
PhEur 2.2.24 Calibration Standards
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
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.
||Polystyrene Test Film - 38 microns thick
||Polystyrene Test Film - 76 microns thick
||Pair of polystyrene calibration films of different thickness. One film is 38 microns and is provided with certification of traceability to five (5) NIST 1921b frequencies. The second film is 76 microns and is provided without certification. Both films are mounted on 2" x 3" cardstock holder with a 19mm aperture for mounting in the universal slide holder in all instruments. Includes instructions for two (2) film ordinate calibration and storage case. Also available with PhEur 2.2.24 certified polystyrene calibration film (inquire for quote).
||Same as 0009-8182, but with PhEur 2.2.24 certified films.
||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.
||Pair of polystyrene calibration films of different thickness cast on KBr, radial symmetry certification, summary of NIST standard 1921 with frequency locations, certification of traceability to five (5) NIST 1921b frequencies, instructions for two (2) film ordinate calibration, slide mount holder. Kit also includes a pair of standard polystyrene films, without NIST traceability certification, mounted on 2" x 4" cardstock which enables mounting in the standard universal slide mount found in all spectrophotometers. Storage case provided.
