The ATR method is used for measurements of mid-infrared fluids. The absorptions, which correspond to the fundamental vibrations of most organic chemicals, fall into the mid-infrared range of the spectrum. However, most of these absorptions are far too strong for a standard transmission analysis. ATR solves this problem because it uses very small optical path lengths. Hellma-Axiom has pioneered the use of ATR for a variety of laboratory and process line tasks and holds a number of important patents in this field.
With the DPR -210 or 212 ATR probe, you can perform rapid FTIR analysis on a wide variety of samples with virtually no sample handling. Just dip the conical sensing head into a sample container of your spectrometer for rapid screening or detailed analysis of liquids, pastes and mud. Rinse the DPR 201 or 212 with a suitable solution and wipe it with a soft cloth or a soft brush. Through the exchangeable ATR elements the performance of most chemical systems can be optimized.

DPR-207 and DMD-270 ATR probes features a small diameter and high assembly flexibility required for many research and process development applications. The key to their small diameter and high efficiency is the use of a single gold light guide to couple the IR radiation to both the probe tip and back to the instrument. This is combined with a patented design that eliminates stray light due to first surface reflections. For optimum performance, these probes should be used with a liquid nitrogen cooled MCT detector.
