Accurate Determination of Sulfuric Acid concentration within the Chemical, Accumulators, Fertilizers and Plastics Industries. The Density – Concentration Relationship of H2SO4 As the Sulfuric Acid concentration increases, the density also increases. This fairly linear relationship goes from 0% concentration up to approximately 96% or 97%. However, somewhere around 93% the linear relationship starts to become […]
ANALYSIS OF CLEANING PRODUCT RAW MATERIALS
Preamble – Measuring Cleaning Product Materials The current crisis is bad, but it is a crisis and will get resolved. One of the left-over effects from it that will persist for many years though is an increased effort on cleaning. Airplane seats, sports venues and even doorknobs on residential houses are going to be subject […]
Measurement of Concentration Dependence of Refractive Index to Confirm Gel Permeation Chromatography Parameter
Measurement of Concentration Dependence of Refractive Index to Confirm Gel Permeation Chromatography Parameter Application Note November 2019 by Gabor Kiss Background: One of the workhorse techniques for polymer characterization is Gel Permeation Chromatography (GPC) which is used to measure molecular weight, molecular weight distribution, degree of branching, radius of gyration, solvent power, etc. The instrument […]
