DeltaNu Advantage 785

The Advantage 785 is our most popular NIR system. Fluorescence usually stems from minor impurities that absorb the laser excitation and emit at the same wavelengths as Raman scattering. This system greatly reduces or eliminates competing fluorescence found in samples using visible excitation. The Advantage 785 comes with a library of over 1200 materials. (808 nm also available)

Ceramic insulator inside oven
Hello, I have an Agilent 7890A GC. I removed the oven shroud inside the oven. When I did so a ceramic insulator that connects to the wire on the heating source broke. I called Agilent and they are not sure if they sell them seperately. I am curious if you have the parts I am looking for?
