Besides immersion probes, Hellma also produces measuring cells for spectroscopic analyses in the laboratory. These can be placed in the sample room or they can be connected using optical fibers (UV / Vis, NIR). Hellma measuring cells are distinguished and named according to their measuring principle.
In the UV/Vis range, you can perform ATR and Transmission measurements. For transmission measurements you can choose a pathlength between 1-10 mm.
In the Mid-Infrared range (IR), you can perform ATR and Transmission measurements. The standard pathlength for transmission measurements is approximately 1 mm.
