Afin de mieux vous servir, JASCO, vous propose différents films polystyrènes pour la validation de vos spectromètres infrarouges.
Films polystyrène ICL certifiés conformes aux recommandations de la Pharmacopée Européenne ( 2.2.24 ).
Nos nouveaux films pour Pharmacopée Européenne ( 2.2.24 ) sont maintenant conformes avec la norme actuelle et avec la révision d'avril 2019.
ICL’s PhEur 2.2.24 Reference Standard is a calibration standard certified to conform to the requirements of Chapter 2.2.24 of the European Pharmacopoeia. Each of these polystyrene reference films is mounted in a convenient holder for easy insertion in the standard slide holder of any IR or FTIR spectrophotometer. PhEur 2.2.24 Reference Standards are certified to the following wave-numbers using a NIST 1921 certified film as a reference standard: 3060 cm -1 , 2849.5 cm -1 , 1942.9 cm -1 , 1601.2 cm -1 , 1583.0 cm -1 , 1154.5 cm -1 and 1028.3 cm -1 . PhEur 2.2.24 calibration standards are certified to show a difference between the absorption maxima to absorption minima at 2849.5cm -1 and 2870cm -1 greater than 0.33 and a difference between the absorption minima and absorption maxima at 1589 cm -1 and 1583 cm -1 greater than 0.08 as required by PhEur 2.2.24.

| 0009-8182 | Pair of polystyrene calibration films of different thickness. One film is 38 microns and is provided with certification of traceability to five (5) NIST 1921 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). |
| 0009-7676 | NIST traceable Polystyrene Test film, certificate of traceability to five (5) NIST 1921 frequencies, set of 2 films each mounted to 2” x 4” cardstock holder |
| 0009-7393 | 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 1921 frequencies, radial symmetry certification for film cast on KBr and storage cases for all films. |
| 0009-7394 | 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 1921 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. |
