| Our spectroscopy labs elucidate your molecular structures from the tiniest to highly complex organic molecules. We also identify and quantify the various components in mixtures with the aid of a range of spectroscopy methods such as NMR spectroscopy, mass spectrometry and optical spectroscopy.
The services provided range from rapid acquisition of spectra to self-interpretation by the client to a complete package of fully interpreted measurements. Our analytical expertise covers virtually all areas of chemical research and chemical production involved in the improvement of synthesis, process and production steps. |

Our equipment and test methods: |
|
 |
- 360 – 600 MHz NMR spectrometer for all nuclei with a magnetic moment (mainly H, C, P, N, F)
- 600 MHz system fitted with a Cold Probe for extremely sensitive measurement of the tiniest amounts of a substance or for rapid measurement in complex NMR experiments. We also use this system to conduct HPLC/NMR online or GC/NMR offline couplings for structure elucidation of mixtures.
