by Helko van den Brom, Gert Rietveld, and Jan Paepen The accurate measurement of small electrical currents is essential for the measurement of ionizing radiation as generated by radionuclides. VSL has been involved in the […]
by Dean C. Ripple, Michael J. Carrier, Richard E. Cavicchi, Christopher B. Montgomery, and Zhishang Hu A common degradation pathway for protein-based drugs is the growth of protein aggregates or particles. Counting and characterization of […]
by Michael Schwartz Today’s new high dynamic range power sensors are not built the same as the older generations of sensors. Older generations of power sensors only had a correction table for their frequency response. […]
by Michael Bair and Tim Francis Fluid pressure is a derived measurand (N/m2) that is realized primarily through manometers and piston gauges at the NMI level. Piston gauges are becoming more useful as primary standards […]
