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.

The Quest’s innovative optical design is based around all reflective gold-coated optics, and features Specac’s Synopti-Focal Array technology with precision-moulded aspheric mirrors. These features allow for a high throughput accessory with an extended wavelength capability suitable for both mid and far-IR spectroscopy.

Interchangeable ATR FTIR crystal puck

Various interchangeable ATR crystal pucks are available for the Quest.

  • High throughput diamond
  • Extended wavelength diamond
  • ZnSe
  • Ge
  • Silicon
  • Specular Reflectance

Each puck is made from hardened stainless steel and held in place on the accessory magnetically making them easily interchangeable without requiring additional alignment.

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
