CRM for UV-Visible Spectroscopy
|
Instruments exclusively employed within the visible region are subject to comparatively less stringent regulation when juxtaposed with their UV counterparts. Nevertheless, adherence to best practices necessitates the rigorous qualification of such instruments to ascertain their optimal performance. Starna offers a comprehensive selection of Certified Reference Materials meticulously tailored for applications within the visible region.
The ideal approach entails the judicious selection of reference materials endowed with calibrated values that effectively encapsulate and encompass the specific analytical conditions envisioned for deployment. |
ABSORBANCE REFERENCE
- Neutral Density Filters (440-635nm) - glass filters with absorbances from 0.04 A to 3.5 A
- Metal-on-Quartz Neutral Density Filters (250-635 nm)– equivalent to NIST SRM 2031
- Starna Green (250-650 nm) - wavelength and absorbance for instruments with bandwidths >5nm
- Combined Holmium/Neutral Density glass (360 - 640 nm) – check absorbance and wavelength with one filter!
- Combined Didymium/Neutral Density glass (430 - 890 nm) – check absorbance and wavelength with one filter!
Wavelength reference
- Holmium Oxide Liquid (240-650 nm) - the most widely used reference for wavelength accuracy
- Didymium Oxide Liquid (290-870 nm) – useful peaks in the NIR
- Starna Green (250-650 nm) - wavelength and absorbance for instruments with bandwidths >5nm
- Holmium Oxide Glass (270-640 nm) – useful for routine checks
- Didymium Glass (430 - 890 nm) – useful for routine checks
- Starna wide-range wavelength reference (335 - 1945 nm) - 20 peaks for wavelength calibration from UV to NIR.
- Starna Holmium Oxide/Neutral Density glass (360 - 640 nm) – check absorbance and wavelength with one filter!
- Starna Didymium Oxide /Neutral Density glass (430 - 890 nm) – check absorbance and wavelength with one filter!
- Samarium Oxide Liquid (230 – 560 nm) – narrow peaks throughout the spectrum
