While formidable masses are comparatively easy to measure, molecules and small particles require advanced techniques, such as mass spectrometry. A flow of new applications have been developed in a variety of fields, ranging from pharmacokinetics and microbiology to chemical analytics and medical diagnostics to environmental and even space research, the instruments often being combined with chromatographic techniques and large databases. This special topic updates you on recent developments.

As demonstrated here, there are a broad range of HPLC applications used in development, production, validation and release of protein therapeutics for human use. Some of the applications mentioned above are mandatory when submitting a new biopharmaceutical to approval at the regulatory agencies. The introduction of the first so-called biosimilars in Europe further increased the demand for highly efficient analysis methods. The continuous development of new stationary phases for the common modes of biochromatography, such as size exclusion, ion exchange and hydrophilic interaction chromatography support biochemists in increasing lab productivity and establishing high-throughput HPLC analysis not only for small molecules but also for large biopolymers more
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 or particle sizes distribution is essential for later application as well as for optimization of the production processes or quality control. In addition the knowledge about the chain structure of macromolecules or biopolymers as well as about the shape of particles is often necessary. For this reason those samples, which often can be very complex systems, have to be separated according to parameters such as e.g. hydrodynamic volume or molecular weight. After the separation process the resulting narrow dispersed fractions are detected with different techniques. more
Today's technology enables the near-perfect determination of trace elements in all concentrations down to the ultra trace range. Modern AAS, ICP-OES, ICP-MS or electrochemical procedures such as voltammetry are reliable and accurate measuring methods for almost every type of task. However, in most cases the sample material has to be supplied in a suitable, measurable form, i.e. as a largely matrix-free solution without contamination or loss of analytes more
In this study, an on-line polyoxometalate cluster (POM)/microfluidic (MF) separation system coupled with inductively coupled plasma mass spectrometry (ICP-MS) detection was developed for the determination of trivalent [Cr(III)] and hexavalent [Cr(VI)] chromium species in aqueous samples. In this sys more
