European Pharmacopoeia Essential Oils for Changes Optical Rotation Measurements
Changes to the European Pharmacopoeia Essential Oils regarding Optical Rotation Measurements / Polarimeter Measurements In April 2022 there is a change coming to the European Pharmacopoeia regarding the measurement of essential oils such as Sweet Orange Oil. The revised monograph requires that samples now need to be measured in a 0.1 dm (10mm) length cell […]
Accurate Determination of Sulfuric Acid Concentration
ACCURATE DETERMINATION OF SULFURIC ACID WITHIN THE CHEMICAL, ACCUMULATORS, FERTILIZERS, METAL, AND PLASTICS INDUSTRIES The Density – Concentration Relationship of H2SO4 As the concentration of the Sulfuric Acid 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 […]
Measurement of Concentration Dependence of Refractive Index to Enhance Gel Permeation Chromatography for Polymer Characterization
Measurement of Concentration Dependence of Refractive Index to Enhance Gel Permeation Chromatography for Polymer Characterization Author: Gabor Kiss Date: October 2019 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 […]
