These Reference Materials can be used to qualify Mid IR – FTIR spectrophotometers for wavelength accuracy over an operating range of 540 cm-1 to 9000 cm-1 (1.1 µm to 18.5 µm). One version of the product can also be used to qualify the resolution of a Mid IR instrument as required by some pharmacopoeias and for the wavelength qualification of ATR (Attenuated Total Reflectance) measurements in the Mid-IR. Another version has additional
certified peaks in the NIR region.
