Specac launch NEW Heated Puck accessory for the Quest™ ATR

Specac are delighted to announce the launch of an all-new heated puck for the market-leading Quest™ ATR. It is capable of analysing both liquid and solid samples at up to 110 °C. Systems that may be studied at this temperature include soaps, oils, trans-fats, and proteins. The puck makes use of monolithic diamond ATR crystals, with ZnSe as an option. Diamond is best for most applications, having excellent physical toughness and chemical resistance, while ZnSe can be useful in the regions where diamond has phonon absorbances.

The stability and accuracy of temperature control is enhanced through the use of a high-precision 4-wire RTD sensor, while the use of monolithic diamond ATR crystals makes the accessory as robust and as chemically resistant as the standard Quest ATR. For the diamond material, in particular, we avoid the use of laminated diamond/ZnSe of our competitors, which is prone to breakage under point loads and narrows the spectral range of the accessory. The temperature of the accessory is controlled from a PC app which plots the current accessory temperature against experiment time, along with the target temperature the program is trying to reach. Several temperature “ramps” and “dwells” may be programmed in the app’s program editor. See the video below for a demonstration of the Quest Heated Puck in action
