Despite the prevailing lack of quality systems that require commercial UV/VIS calibration providers to use a sound science-based calibration methodology in the recertification of spectrophotometer test filters, Stranaska Scientific LLC has recognized for more than 20 years that quality control, systems suitability testing and qualification of UV/VIS spectrophotometers are vital analytical scientific tasks ​which demand the highest scientific metrological attention and rigor. The “one size fits all” approach embraced by ALL other commercial UV/VIS calibration providers simply is inadequate for critical needs in science-based compliance​ and can put laboratories unknowingly at undue risk​.
Most laboratory UV/VIS applications require that the test filters be certified using an advanced calibration model (ACM) that has scientific and metrological traceability rigor exceeding that of the typical consensus calibration model used by ALL other commercial UV/VIS calibration providers. Based on the linkage to its unique NIST heritage, Stranaska Scientific offers UV/VIS calibration options that have different levels of scientific metrological rigor and defensibility. Only Stranaska Scientific customers are provided the special flexibility to select the appropriate option that is commensurate with the level of criticality of the laboratory UV/VIS methods.
