Polystyrene for FTIR, MidIR, and NIR Wavelength Calibration
Starna supplies polystyrene film references for use in the mid-infrared (MidIR) and near-infrared (NIR) with full traceability to National Institute of Standards and Technology.
Starna supplies polystyrene film references for use in the mid-infrared (MidIR) and near-infrared (NIR) with full traceability to National Institute of Standards and Technology (NIST) and covering a total wavelength range from 1.1 µm (8750 cm-1) to 18.5 µm (540 cm-1).
The references are available in two film thicknesses: RM-1921/38 is a 38 µm polystyrene film with 14 certified peaks from 540 cm-1to 3080 cm-1(18.5 µm to 3.25 µm) whose values are traceable to NIST standard reference materials (SRM) 1921b, and RM-1921/65. A thicker version is 65µm thick, and in addition to the 14 peaks in the MidIR, eight peaks are certified in the NIR from 3060 cm-1to 8750 cm-1(3.25 µm to 1.15 µm). These peaks are traceable to NIST SRM 2065. The references are presented as card mounted films in the conventional industry pattern and slip into the standard sample holder of any Fourier-transform infrared spectroscopy (FTIR) instrument.
These references are produced under the company’s ISO 17034 reference material producer accreditation and certified under ISO/IEC 17025 for calibration. They will also comply with the newest revisions of United States Pharmacopeia General Chapters <854> and <1854> on MidIR spectroscopy.
