mixer, under conditions not damaging to the KBr crystals and the pellet is further dehydrated at 200掳C overnight. These conditions assured significant, though not complete, dehydration of the pellets. Such pellets were used to record spectra of carefully selected reference standards. Fifty spectra ...
In addition to typical sample preparation methods (such as micro-extraction, dilution, KBr pellet and mulling techniques), EAG also utilizes various Attenuated Total Reflectance (ATR) accessories, which allows insoluble or multi-layer samples to be examined directly. Ideal Uses of FTIR ...
Press a pellet for XRF with Specac's manual hydraulic press Up to 25 Ton Laboratory Press The manual laboratory press can be optimally used as an XRF press, KBr press, and FTIR press. Although all manual presses come in 15- and 25-ton load configurations, they can also be configured as...

As demonstrated by Faix and Böttcher [40], the traditional KBr pellet method suffers from poor spectral reproducibility caused by various factors including, among others, moisture content in the pellets, room humidity, sample inhomogeneity in the pellet, and variable pellet thickness. In contrast,...
