Standard Golden Gate Diamond ATR

Golden Gate ATR

Durable crystal ATR top-plate

Specac’s Golden Gate™ ATR is a high performance single reflection monolithic diamond ATR sampling accessory, featuring a Type IIIA diamond ATR element metal-bonded into a tungsten carbide mount and providing outstanding durability and exceptional chemical resistance.

ZnSe and KRS-5 lens options are available when ordering the Golden Gate™ ATR; KRS-5 gives a wider range of Mid-IR studies than ZnSe, but with reduced throughput.

Easily adapt your ATR analysis

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 robust design, strength and inherent inertness of the Golden Gate™ diamond ATR element allows the spectral analysis of abrasive, hard, reactive or corrosive samples

Germanium ATR accessory

This ATR spectrometer accessory, with a high refractive index Ge crystal, is suitable for the FTIR ATR analysis of traditionally difficult samples that require controlled penetration of the infrared beam. The shallow depth of penetration of the Germanium Golden Gate™ ATR allows ATR analysis with no band distortion to overcome the often difficult quantitative analysis of strongly infrared absorbing materials.

Optimum sensitivity is achieved using a 4 by 4 mm germanium crystal cemented into a rugged stainless steel disk for maximum strength and support. Corrosive samples, thin films and surface coatings can also be analyzed.

Heated ATR spectroscopy

A high-performance single reflection monolithic diamond ATR product provides the ATR analysis of samples up to 200°C. 

The design of the Heated Golden Gate™ ATR couples the uniquely high thermal conductivity of diamond with a low thermal mass mount in which high power heaters are placed in close proximity to the diamond element to deliver both rapid and efficient, and gives a high degree of temperature control. This facilitates rapid sample analysis. The Heated Golden Gate™ ATR is supplied with a temperature controller with digital readout to 1°C. Low voltage heaters are used, and thermal fuses are fitted as standard for added safety. The controller complies with European CE regulations.

High Temperature ATR

Specac’s High Temperature Golden Gate™ ATR Accessory is a high performance single reflection monolithic diamond ATR product offer for spectroscopic sample analysis of samples up to 300°C. This ATR product extends the capability of the standard Specac Golden Gate™ ATR Accessory and Heated Golden Gate™ ATR Accessory, to provide high-quality spectral data in the high temperature analysis of a broad range of materials including those that are abrasive, hard, reactive, or corrosive. This product is especially well-suited for the spectroscopic analysis of reactions and processes that only occur at temperature.

The High Temperature Golden Gate™ ATR is supplied with a temperature controller with digital readout to 1°C. Low voltage heaters are used, and thermal fuses are fitted as standard for added safety. The controller complies with European CE regulations.

Low Temperature ATR

The Low Temperature Golden Gate™ ATR is a single reflection monolithic diamond ATR accessory for FTIR ATR analysis from -150°C to 80°C. The system uses a thermally insulated copper and stainless steel dewar in conjunction with an integral heater. The high thermal conductivity of the diamond crystal provides rapid temperature stabilisation, accurate temperature measurement, and avoids temperature gradients across the sample.

This ATR product extends the capability of the standard Specac Golden Gate™ ATR Accessory to provide high-quality spectral data in the low temperature analysis of a broad range of materials. This product is especially well-suited for the spectroscopic analysis of reactions and processes that only occur at low temperature.

Micro Specular Reflectance ATR

Specac offer a 45° angle Micro Specular Reflection Top Plate version of Golden Gate™ Accessory is for spectroscopic analysis of flat samples greater than 2mm x 2mm, or powders that can be pressed into a self-supporting wafer.

A scribed reference grid allows accurate repeat positioning of samples.

Reaction Cell ATR

The Reaction Cell Golden Gate™ ATR is a single reflection monolithic diamond ATR accessory for in-compartment FTIR ATR reaction analysis over a broad range of pressure and temperature conditions. This ATR product extends the capability of the standard Specac Golden Gate™ ATR Accessory to provide high-quality spectral reaction analysis at pressures up to 3000 psi and temperatures up to 200°C.

Super Critical Fluids ATR

The Super Critical Fluids Golden Gate™ ATR extends the capability of the standard Specac Golden Gate™ ATR Accessory to provide high-quality spectral data under super critical conditions, with pressures up to 6000 psi and temperatures up to 300°C.

Infrared spectra of super critical fluids, high pressure gases, and liquids, as well as materials subjected to super critical, high pressure gases, and liquids, can be measured. The spectral measurements can be obtained from the gas phase through to the supercritical region and to liquid like densities.

Golden Gate ATR reviews:

  • "I've been using one of these for over 20 years now, producing excellent quality spectra for all types of materials from corrosive, volatile liquids to hard, crystalline solids and everything between. It is a very robust product, very simple-to-use and keep clean. Can be used in both research and QC/factory environments" – Dave Clark of International Paint
  • "Very easy-to-use ATR, high quality IR spectra produced, using only a few mg" – Sami Goussous of Cambridge University
  • "The Heated Golden Gate ATR Accessory is very useful, stable and lasts long. It is very easy-to-use and does great job" – Iman Khazal of University of York
  • "Had two of these for over 10 years. They have been robust, easy-to-use, reliable, accurate and provide rapid results" – Gordon Allison of Aberystwyth University
