Attenuated Total Reflection Probe
The PRO-PROBE-ATR Probe is a Attenuated Total Reflection Probe designed for measuring highly absorbent samples. The ATR Probe is ideal for applications where the absorbance of samples is in the 4000-5000 AU/cm range. The ATR Probe can be inserted directly into the sample and spectra can be taken without sample dilution. Typical applications involve measurement of pure inks, dyes and crude oil samples. What's more, the ATR Probe can be used as a general deposition probe if the refractive index (RI) of the material that is depositing on the probe tip is greater than the RI of the ATR's sapphire crystal or is greater than 1.7.
