Vacuum Ultra Violet Spectroscopy
There are several names given to wavelengths below the Ultra Violet. However, because of the absorption of the air down to few nanometers, and the need to evacuate any part of the environmental
Based on a toroïdal grating design, the TGS (Toroïdal Grating Spectrograph) series are compact flat field spectrographs. In this design, the grating is fixed, which allows achieving a very good stability and compactness. Detector slides over the 40 mm exit flat field of the spectrograph. With a choice of three gratings (both master and replica) the TGS series covers a large VUV range from 9.5 to 170 nm.
The TGS300 is offered as standard, other models can be available upon request.

Clinical chemistry measurements are based on optical spectrometry for most of the blood molecules and also based on potentiometry for a few blood ions.
