Our new metrologist is making good progress in obtaining his qualification. We expect to be able to provide our humidity calibrations around April 2020.
We can now offer a limited range of calibrations:
VSL’s LNG Research and Calibration facility has delivered its first SI-traceable LNG flow meter calibrations results. A total of six flow meters from five leading flow meter manufacturers were calibrated in the test facility using liquid nitrogen.
VSL, the Dutch Metrology Institute, and NIST, the American National Institute of Standards and Technology, are happy to announce the official signing of a new edition of our Declaration of Equivalence, by means of which both institutes recognize the equivalence of Primary Reference Materials prod
A key staff member has recently left VSL and due to this we are not able to calibrate humidity instruments until the second quarter of 2020. A new staff member is currently being trained in this area.
At the end of 2018, the VSL Temperature and Humidity laboratories were moved to different locations within the Metrology Tower building. Unfortunately, due to unexpected laboratory conditions, the opening of the Temperature laboratory got delayed.
Preceding the 14th International Conference on Mercury as a Global Pollutant (ICMGP 2019) (8 – 13 September 2019, Krakow, Poland) VSL and partners host an expert workshop “Comparability of mercury measurements in air” (Sunday 7 September 2019 13:00 – 15:30).
To obtain trace level concentrations for reactive components, the preparation of dynamic gaseous reference materials becomes more and more important.
Volatile Organic Compounds (VOCs) are a group of organic chemicals that have low boiling points and high vapor pressures at ambient conditions.
Nitrogen dioxide (NO2) is the air pollutant which has the greatest impact on human health and wellbeing. A major source of NO2 in cities comes from automotive exhausts. These exhaust gases contain NOx, which refers to mainly NO and NO2.
