RESOLUTION

STRANASKA® Spectral Bandwidth/Resolution Standard

Resolution is one of the instrument parameters that must be tested in accordance with USP guidelines. Compliance can be ensured because spectral bandwidth and resolution testing is now simplified and easy to do! The new STRANASKA method offers several key advantages and improvements over the use of toluene in hexane (TOL/HEX) for this vital performance evaluation and qualification task. In fact, the STRANASKA method does not necessarily require that you need to even purchase a new standard – Stranaska Scientific may be able to add the spectral bandwidth (resolution) functionality to one of the standards that you probably already have.

AVOID RISK – If your spectrophotometer qualification procedure does not include verification and validation of spectral bandwidth (or resolution), your UV/VIS absorption spectra and measurement results may not be correctly interpreted. Misinterpretation of measurement spectra and results can create undue risk that impacts laboratory management decisions.

Stranaska CA2M 719 is a certified reference material artifact that is intended for the verification and validation of the spectral bandwidth (SBW) of molecular absorption spectrophotometers in the ultraviolet (UV) region of the electromagnetic spectrum. First issued in 2015, the CA2M 719 product has been proven to provide significant advantages over the out-dated toluene/hexane solution. The CA2M 719 solution is flame-sealed in a fused-silica cuvette of optical quality. The science-based calibration procedure ensures rigorous measurement traceability of the certified apparent absorbance ratios to the NIST SRM 1935a and/or NIST SRM 2031 series photometric standards.
