Technological Innovation

The core technology of IRUBIS is the microstructured silicon crystal, an innovative sample carrier for ATR infrared spectroscopy.

During the manufacturing process, our sample carriers receive a special MEMS (Microelectromechanical Structuring) on the underside.

While other sample carriers for infrared spectroscopy are usually made of diamonds, zinc selenide or germanium, the IRUBIS crystals are manufactured of silicon wafers. They therefore only cost a fraction while achieving the same high quality results.

The crystals can be purchased separately, we also offer special accessories that are suitable for all standard spectrometers.

In a nutshell: What is ATR infrared spectroscopy?

Infrared spectroscopy uses infrared light (heat radiation) to identify a large number of chemical substances like fluids, solids or gases. ATR stands for attenuated total reflection and is the method of choice for almost all routine analyses of fluids and solids.

In ATR infrared spectroscopy, an infrared light is pointed from below on a crystal, an infrared transparent prism. The light is almost totally reflected on the top surface, but a small part of the energy gets absorbed by the interaction with the molecules in the sample.

This loss of energy is measured and results in a spectrum which contains information about the sample.

We took the MEMS technology to the next level and improved it with our patent-pending signal enhancement technology. In addition to the microstructures on the underside, we also added them to the crystal surface. This leads to higher peaks in the spectrum.
