The DiaMaxATR is the highest performance single reflection diamond ATR available at an unbeatable price.  This accessory is designed not only for straightforward infrared spectroscopy of common laboratory samples like liquids, powders, pastes and solids but also for analysis of challenging samples such as extremely hard solids, abrasive powders and highly corrosive liquids.  The sampling plate features a high performance diamond crystal sealed into a chemically resistant stainless steel.  It can be readily removed from the base and snaps firmly into place.  Tamper-resistant adjustments are provided to allow for optimal performance with virtually any infrared spectrometer.   This accessory is enclosed for purge.  Liquid are measured by simply placing a drop on the crystal.  Solids can be compressed against the ATR crystal using the built-in pressure applicator with its force-limited slip-clutch.  Optional heated and flow cells are available, along with a force sensor with digital read-out for more precise compression.
