WHY MEASURE INVERT SUGAR ? – BACKGROUND Inverted sugar syrup, also called invert syrup is essentially sugar in water. Hydrolytic saccharification of sucrose produces invert sugar, a mixture of the monosaccharides glucose and fructose. The mixture rotates light in the opposite direction of the original sugar, which is why it’s referred to as invert sugar. […]

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 […]
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: Gel Permeation Chromatography Refractometer 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 […]
Medición de la dependencia de la concentración del índice de refracción para mejorar la cromatografía de permeación en gel para la caracterización de polímeros
Medición de la dependencia de la concentración del índice de refracción para mejorar la cromatografía de permeación en gel para la caracterización de polímeros Autor: Gabor Kiss Fecha: Octubre 2019 Antecedentes: Una de las técnicas caballo de batalla para la caracterización de polímeros es la Cromatografía de Permeación en Gel (GPC) que se utiliza para medir el peso molecular, la distribución del peso molecular, el grado de ramificación, el radio de giro, el poder disolvente, etc. La [...]
