Chlorine Production - Eliminating Mercury

The role of trace element analysis in the membrane process

20-09-2013

Nearly all industrial chlorine production is by the electrolysis of brine using a membrane cell. The efficiency of the membrane process can be impaired by the presence of trace impurities in the brine. This can be done using Inductively Coupled Plasma–Optical Emission Spectroscopy (ICP-OES). This ...

Sample Preparation for MALDI Imaging with SunCollect System

02-11-2012

During the last years, matrix-assisted laser desorption/ionization mass spectrometry has been subject to considerable improvements. Whereas the focus of MALDI before has mostly been on the analysis of peptides and proteins, the development and progress of MALDI imaging have clearly expanded its ...

A granular look at sugar

Use of novel analysis methods

12-01-2011

Our experience with sugar starts in early childhood – since breast milk contains lactose. Human sensory perception alone is, however, not enough to properly assess the useful but also potentially harmful effects of an age-old sweetener (saccharose). Nutrition researchers and physicians have, for ...

Field-Flow Fractionation - The Universal Separation Principle for Particle and Macromolecule Characterization

22-09-2010

High molecular weight polymers, bio molecules or particles in a range of a few nanometers up to several microns are more and more important in science and technology. Many applications are based on the specific properties of these materials. For this reason, an exact knowledge of the molar mass ...

Size and element specific determination of Ag nanoparticles in consumer spray products using asymmetric flow field flow fractionation (AF4) coupled to ICPMS

10-09-2010

The use of nanoparticles in consumer products shows a tremendous increase over the past years. A study of the Woodrow Wilson International Centre for Scholars reported that between 2005 and today the number of products based on nanoparticles increased almost twentyfold from 54 to 1015. As active ...

Absolute Molar Mass Characterisation

27-11-2009

Multi-angle light scattering coupled to SEC or other fractionation methods can provide an absolute means for measuring the molar mass, size and distribution of proteins, polymers and particles of all sorts. Wyatt Technology's MALS also enables the elucidation of additional data such as branching, ...
