Durable diamond ATR Specac’s Golden Gate™ ATR is a high-performance single reflection monolithic diamond ATR sampling accessory, featuring a diamond ATR element metal-bonded into a tungsten carbide mount, providing outstanding durability and exceptional chemical resistance. The robust design, strength, and inherent inertness of the Golden Gate™ diamond ATR element allows the spectral analysis of abrasive, hard, reactive, or corrosive samples. Focusing optics The Golden Gate uses focusing lenses to achieve a tightly focused beam on the diamond ATR crystal. The standard lens material is ZnSe but KRS-5 lenses are also available as an option where access to the lower wavenumber region of the spectrum is required. Easily adapt your ATR analysis The demountable nature of the top plate enables it to be replaced with one that allows non-ambient spectroscopic analyses under different conditions of temperature and pressure. It also carries an advantage in 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.
