Low Temperature Golden Gate^™ ATR Accessory by Specac Ltd

Specac’s Low Temperature Golden Gate™ ATR Accessory is a high performance single reflection monolithic diamond ATR product. Samples can be analysed spectroscopically while being cooled to -150 °C or heated up to 80 °C. The high thermal conductivity of the diamond crystal provides rapid temperature stabilisation, accurate temperature measurement, and avoids temperature gradients across the sample.

Its key features include:

• A robust and strong design
• Continuous temperature control
• Little or no sample preparation is required
• Cooling down to -150 °C

The coolable top-plate is interchangeable with the other compatible Golden Gate top-plates such as the heated, reaction cell, or super critical fluids top plates. The demountable nature of the top plate is well suited for the preparation of toxic or harmful materials, as they can be prepared in a glove box, sealed, and then measured with a higher degree of operator protection than other infrared sampling methods.

The Golden Gate™ ATR series are particularly appropriate for samples that may polymerise or set during analysis since they can be cleaned off with a knife or abrasive pad without damaging the diamond ATR crystal. Good quality spectra can be achieved from liquids, gels, powders and even hard rocks. Special anvils are available to hold polymer pellets, to seal in and run air/moisture sensitive samples, and to analyse coatings on wires.
