Diamonds, Nanotubes and Onions made from Carbon

The product portfolio of Berlin based LUM GmbH provides innovative analytical instruments for the characterization of the entire life cycle of carbon materials, for carbon black and graphene, nano-diamonds, Carbon nanotubes and Carbon onions.

For the quality control of raw materials, on the basis of their particle size distributions, the Dispersion Analyser LUMiSizer is used for nanoparticles. For the characterization of dispersibility and separation stability or shelf life the user needs to know the product properties in its original concentration. This requirement is also fulfilled by all measuring instruments of the product families LUMiSizer and LUMiReader. Depending on the formulation properties and application the samples are measured in real-time or directly physically accelerated, to obtain the information in time lapse mode, instead of waiting for weeks, months or even years.

Complex interactions between particle surface properties, dispersibility and resulting suspension quality can be described by the Hansen Dispersibility Parameters. Prof. Dr. Lerche, Managing Director of LUM GmbH, is invited to show all conference participants an easy measuring approach for carbon black, with his scientific talk Carbon allotrope particle surface changes due to applied dispersing energy.

Applying Centrifugal Adhesion Testing Technology the LUMiFrac instrument determines adhesive and bonding strengths of composites. So it is used not only for coatings and treated surfaces but also for the characterization of composite materials, e.g. in automotive or aviation industries. Featuring a large force range and a clamping-free sample preparation, the LUMiFrac offers a wide application range. The simultaneous analysis of up to eight samples provides the operator with a high sample throughput under identical test conditions.

LUM is pleased to be a selected Diamond Sponsor of the NanoCarbon Conference 2019 to support the further scientific development of the nanocarbon research areas.
