NIST-Compliant and NIST-Traceable Stray Light Calibration Standards are calibrated in the ISO-17025 accredited facility and are traceable to NIST SRM 2032 (www.NIST.gov/srm).

These stray light (SL) calibration standards are key spectrophotometry validation standards in accordance with requirements of European (Ph.Eur), US (Chapters 857 and 1857), British, and Canadian pharmacopoeias.

Liquid SL calibration standards are offered with various spectral ranges (please see in [ ] below) and corresponding nominal cut-off wavelengths at 2.0A (please see in { } below):

Aqueous potassium chloride [190nm - 210nm], {200nm}

Aqueous sodium iodide or potassium iodide [210nm - 270nm], {260nm}

Acetone [250nm - 330nm],  {326nm]

Aqueous sodium nitrite [300nm - 400nm], {391nm}

Solid-State SL calibration standards are offered for the same cut-off wavelengths as said above.

We also manufacture a large selection of SL calibration standards with custom cut-off wavelengths. Please contact us for for more information.
