Measuring the invisible: VSL’s Picodrift interferometer is pushing the limits of precision
This level of ultra-precision measurement is now helping to solve critical challenges in industry and science.
Thanks to White Rabbit, all Watches are Synced
The Netherlands is constructing a network capable of transmitting time with an accuracy of mere billionths of a second. Initially aimed at scientific research applications, it is anticipated that this ultra-precise timing will soon find everyday uses as well.
The lack of fit-for-purpose hydrogen standards could potentially the bottleneck of the hydrogen economy.
An article about the need for appropriate hydrogen standards
VSL explains how insulating a flowmeter can affect the flowmeter temperature measurement value
VSL explains how insulating a flowmeter can affect the flowmeter temperature measurement value and how this can affect the mass flow output.
VSL successfully completes calibration test with hydrogen-enriched natural gas
Report on the effect of hydrogen-admixture on the accuracy of high pressure flow measurement.
Guideline for the preparation and analysis of gaseous reference materials of indoor air pollutants
A healthy indoor environment can be achieved by controlling the sources and by eliminating or limiting the release of harmful substances into the air. One way is to use materials proven to be low emitting.
A new look at the sorption kinetics in reference gas standards
In the MetClimVOC project (https://www.metclimvoc.eu/), VSL developed an innovative approach to follow the adsorption and desorption phenomena of low levels of methanol in cylinders based on the use of different methanol isotopes and a new laser spectroscopic method able to discriminate them.
A formalism for traceable dosimetry in superficial electronic brachytherapy
Brachytherapy is an effective treatment option for many types of cancer. A newer variant, electronic brachytherapy (eBT), is increasingly used – but without a formal and traceable method to determine radiation dose.
Design of gravimetric primary standards for field-testing of hydrogen refuelling stations
The Federal Institute of Metrology METAS developed a Hydrogen Field Test Standard (HFTS) that can be used for field verification and calibration of hydrogen refuelling stations.
