WebThe precision of the Thermal-Optical method of analysis, measured as a relative standard deviation, falls into the 4-6% range for samples that are in the concentration ranges of 5 to 400ug/cm2 for OC, and 1 to 15ug/cm2 for EC. This relative standard deviation range applies to the OC/EC speciation values as well as to the total carbon.

WebDec 12, 2011 · Kinetic methods of analysis are based on the fact that for most reactions the rate of the reaction and the analytical signal increase with an increase of the analyte concentration. In kinetic methods, measurement of the analytical signal is made under dynamic conditions in which the concentrations of reactants and products are changing … WebSep 11, 2024 · 10: Spectroscopic Methods. An early example of a colorimetric analysis is Nessler’s method for ammonia, which was introduced in 1856. Nessler found that adding an alkaline solution of HgI 2 and KI to a dilute solution of ammonia produced a yellow-to-reddish brown colloid, in which the colloid’s color depended on the concentration of … WebBecause current methods of measuring these aerosols — optical and thermal — produce method-specific results, one can never be sure whether concentrations of black carbon or elemental carbon measured with different techniques really are comparable. In extreme cases, method-specific differences can be a factor of two. how to sync safari favorites with edge
