This Reference Material can be used to Estimate the Stray Light (Stray Radiant Energy) of Near Infrared spectrophotometers at approximately 2365 nm.

Spectroscopic grade chloroform, is permanently sealed by heat fusion in a high quality far UV quartz cell. Heat sealing the cell in this way virtually eliminates the risks associated with handling this volatile, hazardous substance.

The spectrum shows a cut - off (i.e. Absorbance >2.0A) at approximately 2365 nm. Any light detected within ± 20 nm of this wavelength will be stray light. For the measurement to be meaningful, the spectrophotometer should have a bandwidth such that the spectral distribution at 2365 nm does not exceed ± 20 nm. 

 

RM-CHCL3 

chloroform-NIR

The certified cut-off wavelength is the wavelength at approximately 2365 nm at which the absorbance value exceeds 2.00 A
