Second-generation Polymer Fluorescent References Expands the Possibilities of Fluorescent Calibration

Starna fluorescent polymer references are well known and have been a de facto industry standard, dating back to the 1960s, for wavelength calibration and the monitoring of instrument performance in fluorescent applications.

The development by Starna of second-generation polymer references based upon new proprietary dyes expand on this capability. With increased stability and resistance to photo-bleaching, the performance of these materials is extended to allow their use as relative photometric intensity references.

Development of these second-generation materials, specifically under Starna’s ISO 17034 accreditation, has ensured appropriate stability and homogeneity studies. This is in line with the essential requirements of this Standard, which have to be met for reference material production.

These materials can therefore be used to qualify a wide variety of fluorescent instrumentation and provide traceability of measurement, facilitating comparison between measurements on a given instrument and between systems.

They are available in a variety of physical formats and concentrations, which may be optimised for specific instruments and applications. A range of concentrations further provide the possibility for linearity verification.

Starna offers a range of polymer, glass, and sintered formats as well as sealed liquid fluorescent reference materials to allow the testing of wavelength, spectral response, sensitivity and signal-to-noise.
