IR Sphinx ATR Product Family

IR Sphinx ATR product range uses the concept of Attenuated Total Reflection to record an infrared spectrum of a sample. The products are available in the wavelength range from 2.5–5.0 µm or of 5.5–11.0 µm. The spectral resolution varies between 18cm-1 and 36cm-1. All spectrometers include our proprietary software SphinxSuite which runs on all commonly used operating systems. The products are battery operated without having any moving parts and are designed to be truly portable. The IR Sphinx ATR spectrometer are available in three different configurations namely IR Sphinx Lab, IR Sphinx Industrial or IR Sphinx Portable.

All configurations can also be adapted for the following applications:

Continuous monitoring:

  • The ATR interface is modified with a special flow through cell to enable continuous monitoring

Constant pressure:

  • The ATR spectrometer are modified with a dedicated sample clamping mechanism that ensures that the pressure with which the sample is pressed onto the ATR crystal remains constant

SphinxSuite Software


The IR SphinxSuite software package is compatible with MS Windows PCs and tablets (XP / Win7 /Win8 / Win10). The software is intuitively structured, consisting of modular building blocks that allow each individual user to quickly configure and customize the software’s GUI for different applications and different skill levels of the user.

The user can currently choose from the following software modules:

Numerous Applications

Spectrolytic’s sensor platform analyses samples based on their mid-infrared (2–12 µm) absorption properties. We are working closely with our customers and the list of applications is expanding and the links on the page are continuously updated with new and exciting applications.

Oil Condition Monitoring

Lubrication is used everywhere in the modern world to reduce friction between moving parts. Frictions in many cases is undesired as it simply creates heat and reduces efficiency. One of the major lubricants used in today’s world is oil which come in different formats such as mineral oils, vegetable oils or synthetic oils.

The key focus of oil condition monitoring is on heavy/expensive equipment where the cost of failure can be significant, either due to replacement cost of an engine or due to loss of earnings in the period of downtime.

Lubricants for such demanding applications are optimised to take into account the specific working condition of the machinery such as operating temperature, load and speed. The understanding of the condition and the performance of the lubricant in a machine is therefore of vital importance to reduce unscheduled down-time and to improve efficiencies.

Key application areas where our equipment is used to monitor the condition of the oil are listed below and please follow the link (oil condition monitoring) to learn more about the topic and to find detailed application notes for specific applications.

Oil Condition Monitoring

  • Engine oils
  • Gearbox oils
  • Hydraulic oils
  • Grease

Fuel analysis

Time is money and fuel is the stuff that helps us moving from A to B as fast as possible. People as well as organisation rely on fuel as a power source that is used to operate heavy machinery or to ferry people around in planes, ships or cars. Any downtime due to contaminated fuels can be very costly.

Environmental aspects are also becoming increasingly important as governments are tightening the emission regulations of any engine driven vehicle related to CO2, NOx etc. It is therefore important that the correct fuels are used and that reliable controls along the fuel supply chain are in place.

Our portable fuel analyser enables our customers to carry detailed scientific analysis in the field anywhere and at any time. The results are available within minutes and provide clear indication about the quality of fuel.

The key focal areas of fuel analysis are listed below and please follow the link (Fuel analysis) to learn more about the topic and to find detailed application notes for specific issues.

Fuel analysis

  • Biofuels
  • Oil & Fuel mixtures
  • Fuel contamination

Agricultural Applications

Precision farming is a management strategy which identifies, analyses and manages within field variability for increased profit and reduced environmental impact. Preparing the soil by adding manure and using sophisticated spraying tools for fertilisation are all part of improving the efficiency of farming. All produce, fertilisers and chemicals are organic by nature and therefore our portable mid-infrared spectrometers are very powerful tools for the farmer to get relevant information in real time.

Our technology also provides valuable information along the supply chain of the relevant products to ensure that the final product arrives at the customer at the same quality as it left the fields / processing plants.

Together with our customers we are actively working in the applications listed below but we are always looking out for new applications. Please contact us to discuss your needs.

Agricultural Application

  • Manure analysis

Food Quality

Consumers are becoming more demanding and knowledgeable and it is therefore important to ensure excellent quality control along the supply chain. Detailed analytical checks of the foods during the different stages are often difficult as no relevant test equipment is available or laboratories are either too far away or the turn-around time for samples is too long.

With our products we are providing a cost effective solution to the food industry to carry out relevant analytical tests on foods in real time and at any place. Our products provide a lab in a box without the need for any additional chemicals or consumable.

We are working together with our customers on the applications listed below and please follow the link (Food Quality) to learn more about the topics and to find detailed application notes for selected specific applications.
