Why are reactive gases measurements a huge challenge?

02/27/2018

In the last decades sensitive analytical techniques have become available for measuring reactive gases in air even at part-per-billions levels. However, less progress has been made in developing materials compatible with those gases.

Sub-millikelvin traceability for water calorimeter

02/27/2018

Ionizing radiation is used as treatment in cancer therapy. For the treatment it is necessary to control the exact position and dose of the radiation as a too low dose will not kill all the cancer cells and a too high dose will cause too much damage in healthy tissue.

Traceability of mercury measurement results

02/27/2018

A novel mercury vapor generator was developed to establish metrological traceability of mercury measurement results, based upon a gravimetric approach, for ambient air levels as well as higher concentrations.

How measurements can contribute to improved healthcare?

12/18/2017

In preparation for the call ‘Metrology for Health’ that is issued in the European Metrology Programma for Innovation and Research (EMPIR), VSL organized a workshop and networking meeting, which brought together more than 20 participants from medical industry, universities and academic hospitals.

Better flow measurement, safer patients

Vulnerable patients receiving drug infusions in intensive care or for palliative relief require low volume drug delivery over extended time periods.

Virtual standards, real advantages

09/26/2017

Atomic force microscopy (AFM) is a powerful technique to measure surface characteristics on the nanometer scale. AFM is based on scanning a measurement probe over the surface under study while recording the interaction between the probe and surface.

First proficiency test on the siloxane content in biomethane

09/21/2017

Siloxanes are silicon-containing volatile organic compounds which occur in biomethane and upgraded biogas. They are formed during the fermentation of organic matter, both in fermenters as well as in landfills. The maximum permissible levels in biomethane are regulated in EN 16723.
