A new series of five polymer block fluorescence references from Starna Scientific can be supplied with certified spectral scans for spectral correction that are traceable to NIST Standard Reference Materials. In some cases, they can be traceably certified for calibrated intensity as well. Designed for the routine performance qualification of fluorescence spectrophotometers and fluorimeters, they can be used in both continuous- and flash-source instruments and a wide spectral range allows the user to select a reference material with broadly similar spectral properties to those of the analyte. They are available in a variety of physical formats, suitable for use in conventional spectrofluorometers or for specialist applications such as microscopy or PCR.
