High-performance ATR spectrometer accessory

The Quest ATR Accessory is a performance single-reflection ATR accessory from Specac designed for laboratory spectroscopic sample analysis in the mid- and far-infrared. With innovative optical design and durable monolithic diamond ATR crystal option, this sets the benchmark in performance and value for ATR spectroscopy. 

Interchangeable ATR-FTIR crystal pucks

Various interchangeable ATR crystal pucks are available for the Quest.

The Quest ATR FTIR accessory uses easy-to-remove pucks with diamond, extended range diamond, Germanium, ZnSe, Silicon and Specular Reflectance crystals.

*at 1000 cm-1. Calculated for a 45° angle of incidence and a sample refractive index of 1.5. 

Each puck is made from hardened stainless-steel and locates magnetically on the accessory, making them easily interchangeable without requiring additional alignment. 

Heated puck NEW

The Heated Puck enables high temperature measurements up to 110 °C, perfect for analysis of phase changes in soaps, food stuffs, and other multi-phase systems. A highly sensitive 4-wire RTD sensor is used for temperature measurement, while control is provided by a compact USB interface and a free PC-based software app.  

The heated puck is available with either a high throughput diamond ATR crystal or a ZnSe crystal.  

Pucks for easy liquid sampling 

Liquid pucks have a raised surface around the crystal, forming a bowl to confine samples on the crystal. This is useful for samples with low viscosity or prone to evaporation.  The bowl has a volume of approximately 100 µL. 

The pressure tower 

The Quest™ has a pressure tower which allows a clamping load of up to 40 lbs to be applied to solid samples to ensure full contact with the crystal. The tower gives an audible click when its pre-set load has been reached. 

Flow anvil 

The flow anvil enables samples to be flowed over the crystal at low flow rates and low pressures using a syringe. It has an internal volume of 28 µL and is held in place with the pressure tower. 

Compatable with measurement standards

Method Number  
Determination of Biodiesel by FTIR-ATR-PLS ASTM D7371

Quest ATR accessory reviews

  • "We have been testing liquids, powders (deposits) and plastics with absolutely no problems for the last 3 years"Marco Nunes of Cariri
  • "Of particular note is the use of all-reflective optics and the availability of an extended-range diamond option"Philip Ash of University of Oxford
  • "These diamond ATR units are practically indestructible and  extremely easy to clean and can be swapped out for liquid or gas cells very easily" – Susan Gannon of University of Glasgow‚Äč
  • "Perfect for organic chemistry practicals" – Peter Brien of Trinity College Dublin
