The PTRam is a compact, sensitive, and robust Raman spectrometer that can be placed on the bench or in a rack-mount cart. Just connect the fiber optic probe, plug it in and start your measurements, easily moving it to the process you are developing. With the PTRam you can increase your process understanding and decrease development time with real-time process monitoring.

In addition, the PTRam is a stable system, with high repeatability and reproducibility. It includes internal monitoring of system temperature and Raman shift, ensuring precise measurements throughout your analysis.

Flexible sampling accessories

PTRam

Fiber-optic sampling makes it easy to take your measurement to your sample, and measure through the transparent vessel wall.

The interchangeable fiber-optic probe shaft expands the capabilities of the PTRam with shafts operable in diverse environments. We also offer custom sampling interfaces suited to your unique needs.
