Harrick's SplitPea™ is a horizontal ATR accessory with the smallest sampling area of any ATR accessory - less than 250 µm in diameter for its Si ATR crystal and less than 500 µm in diameterfor its diamond ATR. The SplitPea™ is configured to apply localized, measured pressure to produce superior contact between the sample and the ATR crystal. This makes the it ideal for quick and easy spectroscopy measurements for a wide range of samples. These include: hard samples, like paint chips and combinatorial chemistry substrates; small samples, such as individual fibers and nanoliters of liquids; large samples, such as transparency film and defects thereon. For positioning samples on the sampling area, a 50X viewing microscope is available. In addition to making ATR nanosampling simple and straightforward, the SplitPea™ features PermaPurge™ for rapid sample and crystal exchange without interrupting the purge of the spectrometer. The Harrick SplitPea™ HATR accessory is an innovative alternative to infrared microscopes, beam condensers, and diamond cells.
