SplitPea™ ATR Microsampler - UNS-XXX

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. 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.

Features

• ATR and specular reflection capabilities provide application versatility.
• High sample throughput due to little or no sample preparation.
• Usually retains sample integrity.
• Small sampling area - less than 250 µm in diameter for ATR with a silicon crystal and less than 500 µm in diameter for diamond.
• Minimizes stray light due to the small sampling area.
• Inert ATR crystals available for use from the NIR to the Far-IR.
• Calibrated pressure applicator for reproducible ATR measurements.
• Designed for optimal contact between the ATR crystal and hard surface solids.
• Flip-up, streamlined pressure applicator for easy access to sampling area.
• High energy throughput with DTGS detectors.
• Harrick's exclusive PermaPurge™ allows rapid sample and ATR crystal exchange without interrupting the purge of the FT-IR system.
• Spill-resistant cover.
• Options include Flow-Through Liquid Cell and Heatable Sampling Plates for operation to 200°C.

Includes

• Two ATR holders with mounted Si hemispheres or one ATR holder with a mounted diamond ATR hemisphere.
• Powder Retainer for studying powders by ATR.
• Specular reflection sample holder and alignment mirror.
• Mating hardware for the specified FT-IR spectrometer.
