Raman Spectroscopy is a fast, non-destructive method for measuring the composition of chemical compounds. In just seconds, the Raman effect can identify the different molecules and their quantities in sample types including solids, liquids, gasses, powders, pastes, and gels without damaging or destroying the sample.

Some examples of Raman Spectroscopy in action include:


      • Measuring glucose and lactate levels in a bioprocess
      • Full hydrocarbon analysis of natural gas
      • Categorizing concentration of omega 3 and 6 fats in salmon fillets
      • Identifying density and melt index of polymers
      • Measuring hydrogen gas concentration
What is Raman: TouchRaman Probes


Our simple-to-use, one-click instrumentation uses a laser as the light source. The sample is illuminated, and the filtered scattered Raman photons are dispersed onto an imaging detector. The intensity of the dispersed photons onto the detector are plotted as a spectrum. The information-rich spectrum contains unique chemical information to determine both chemical identity and concentration.

Raman analyzers are regularly used in research, product development, process development, manufacturing, process control and quality control in many industries; oil & gas, petrochem & polymers, biotech & pharmaceuticals, food & beverage, and academic & government.
