Good Results: The following table shows results obtained for a CaO material using a Spectro Analytical Instruments Halogen (UV Plus) spectrometer. This test was done primarily to check delivery smoothness of the PowderPump™, taking five (5) replicate measurements over perhaps sixty (60) seconds. Better RSD's (relative standard deviations) were likely possible by integrating data collection over the entire sample delivery and normalizing the data to the mass of sample delivered. (Mass of sample may be determined by measuring mass of vial before and after sampling, giving the mass of sample delivered to the plasma.) Note Cl, Br,I in the results:
