Starna Scientificss Certified Reference Materials (CRM) for fluorescence spectroscopy have been specifically designed and developed for applications that require day-to-day validation and long term monitoring of fluorescence system responsivity.
Starna Fluorescent references are frequently used in the following types of system:
- ELISA fluorescent plate-readers
- PCR systems
- Point-of-care fluorescent based systems
Measurements on fluorescence based measurement systems are typically subject to a large number of instrumental variables. A given sample may give significantly different results when measured on different instruments even if they are of similar design.
The measurable signal of fluorescent analytes can be impacted by a number of chemical and physical effects, such as quenching or self-absorption of the fluorescence emission, which may lead to departures from the expected concentration/emission relationships outside of a narrow range. Additionally, many fluorescent materials are susceptible to photobleaching, such that detectable signal may noticeably fade with repeated measurement.
Therefore, to ensure confidence in results, a stable and consistent point of measurement reference should be used minimise or remove the effects of these variables.
Where applicable, specific properties of fluorescent CRM can be made tracible to NIST Standard Reference Materials in our ISO/IEC 17025 calibration laboratory.
All fluorescent CRM are manufactured in our ISO 17034 accredited Reference Material Production facility.
