Milligram mass metrology for quantitative deposition of liquid samples
Gordon A. Shaw
Quantitative dispensing of liquids by mass becomes increasingly difficult as sample volume decreases. Whereas ml quantities of liquid can be directly weighed as dispensed on an ana…

Meta-study of laser power calibrations ranging 20 orders of magnitude with traceability to the kilogram
Paul A. Williams, Matthew T. Spidell, Joshua A. Hadler +11
Laser power metrology at the National Institute of Standards and Technology (NIST) ranges 20 orders of magnitude from photon-counting (1000 photons/s) to 100 kW (10^23 photons/s at…
