NEW: Silicon ATR Puck & Specular Reflectance ATR Puck

We have developed and released two new pucks for the Quest ATR accessory: Silicon and Specular Reflectance.


Silicon ATR Puck for the Quest accessory

Along with the standard options of diamond, ZnSe and germanium crystal puck options for use of Specac’s Quest ATR accessory, a new silicon crystal puck option (P/N GS10819) has been introduced.

Silicon and Specular Reflectance ATR Pucks are now available for the Specac Quest ATR spectrometer accessory.

A silicon crystal puck option of use allows for spectral collection of liquid and solid sample types into the Far IR region should this be necessary, at a fraction of the cost associated with use of an extended range diamond crystal puck option.

  • solid and liquid samples handled
  • 45° Incident angle for ATR study
  • sample penetration depth circa 0.9 microns
  • far IR spectral region measurement

Specular Reflectance ATR Puck for the Quest accessory

In addition to the new silicon crystal puck, a specular reflectance puck P/N GS10816 can now be offered using the optical unit of the Quest ATR accessory.

Silicon and Specular Reflectance ATR Pucks are now available for the Specac Quest ATR spectrometer accessory.

A solid sample is placed over an aperture hole of the puck assembly for a specular reflectance measurement to be made at a nominal 45° incident angle to the sample surface. A reference mirror is supplied with this puck option to use for collecting a reference background.

  • solid samples with thin surface films for measurement
  • 45° Incident angle for specular reflectance study
  • aluminium polished coated reference mirror supplied

Analyzing legal highs with ATR spectroscopy

Quick recap, Mia was asked to test 12 unmarked samples and detect the dangerous legal high known as mephedrone, for the Staffordshire Police Force.

Combining GCMS and ATR spectroscopy, Mia developed a quick, simple and efficient method for detecting and confirming drug samples.

Select Science interviewed Mia Abbott on her use of the Quest ATR-FTIR spectrometer accessory in her research and she was very pleased with the tool.

I like FTIR because it was fast... The (Quest) ATR was brilliant for the fact that it didn’t require sample preparation, which was a major advantage over the GCMS.

Quest ATR spectrometer accessory reviews

Reviews of our Quest ATR commented on its consistent performance, versatility across various sample types, ease-of-use, high throughput and durability. Read through the reviews below.

  • "This ATR is so easy to use. We have been testing liquids, powders (deposits) and plastics with absolutely no problems for the last 3 years. We see no loss of performance. Easy to clip in and out of our Shimadzu FTIR." – Marco Nunes of Cariri
  • "The Quest is a versatile ATR accessory, due to the easily interchangeable ATR 'pucks' that allow rapid switching over a broad spectral range and sample requirement. Of particular note is the use of all-reflective optics and the availability of an extended-range diamond option. This places the Quest amongst the best ATR accessories available for both routine characterisation and more demanding applications in a research environment." – Phillip Ash of University of Oxford
  • "Allows us to have a much quicker throughput by reducing sample prep. time and allows successful handling of small samples by students." – John Woodard of Chapman University
  • "This product is fantastic, we replaced the old plates in our IRs with these as they were continuously getting damaged and misused in the teaching labs. 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
  • "Very valuable tool when fast turnaround is required. Perfect for organic chemistry practicals." – Peter Brien of Trinity College Dublin
  • "This is a simple to use high quality ATR for FTIR, a good accessory to add to a standard instrument." – Robert Jacobs of University of Oxford
