ATR Probe for Lab and Process Applications
Sep 10 2014
Attenuated Total Reflectance enables direct measurement to be made in very strongly absorbing samples. The Katana Range of ATR probes from Hellma Analytics are available in 6mm and 12mm diameter versions both using a Sapphire crystal. Their three-bounce optics gives an effective path-length of around 1µm, generating an effective dilution of 10,000 times versus a standard 10mm path-length cuvette.
These probes can be configured for lab and process applications at www.mypatprobe.com and can be manufactured in a range of materials depending on their usage. They can be supplied with fixed fibre-optic cables or SMA connectors as required. Versions are also available for use in the UV (240 to 1100nm) or NIR (400 to 2300nm) wavelength ranges.
ATR measurements are made by the loses in the evanescent wave that passes through the crystal, making the probe a sealed unit, and so requiring minimal maintenance compared to other types of optical immersion probe.
