Tveskaeg Lab

Tveskaeg Lab is a version for direct NMR isotope analysis in laboratories. The Operator initially transfers a sample into a blending scale. If dry matter content in the sample is estimated to be high, the operator can choose to add water. A hand blender is used to obtain a homogeneous sample prior to analysis. Tveskaeg Lab will automatically compensate final analysis results for any dilution applied.

  • No sample pre-treatment required
  • Up to 100% dry matter analysis of matter blendable with water
  • In-line weight scale for mass ppm (mg/kg) results, as well as volume ppm (mg/L)
  • Auto cleaning of blending scale before next measurement
  • Auto calibration for all NMR isotopes via content of oxygen and hydrogen in tap water

Who is NanoNord?

Nanonord - Who we are, and what we do.

NanoNord first launched the product Catguard, which was the world’s first device using the NMR technology to measure catfines in heavy fuel oil. The latest product to be introduced is Tveskaeg, which like its predecessor uses the NMR technology.
