Multi Detection Gel permeation chromatography Analysis of Polymers GPC/SEC is the only chromatographic technique that can determine the molecular weight distribution of a polymer. Adding advanced detection boosts this capability, improving both the accuracy and information
Content of the experiment. Dual-angle light scattering or viscometer detectors not only provide more accurate molecular weights, but also an insight into the behavior of the polymer in solution. The 1260 Infinity MDS is an integrated detector suite designed as a simple add-on to any liquid chromatography system allowing all forms of GPC analysis to be performed.

Performance advantages of Moxtek’s Pro-Flux polarizers in the range from UV to NIR There are many fields of application in science and technique for polarizers: for instance in researching of mechanical stress allocation in transparent objects via polarized light, for organic structure analysis, in saccharimetry and particularly in crystal optics, astronomy, photography. Moxtek’s polarizers UVD260 and UVD240 Proflux series manufactured via nanowire® fabrication technology and have several benefits in comparison with traditional Glan-Taylor and Glan-Thompson polarizers which applied in spectroscopy. Due to advantages and design features of UVD polarizers managed to reach high quality of polarization over a wide spectral range from UV to IR.

Microwave Plasma Atomic Emission Spectroscopy: New Elemental Analysis Method Microwave radiation to generate the plasma burner, torches are used more than 50 years. For analytical purposes, the study of microwave plasma discharge in a microwave field was carried out in parallel with the development of the method of analysis is widely used in the 1990s and known as inductively coupled plasma optical emission spectroscopy (ICP-OES). Only recently the optimal conditions for the use of microwave radiation to produce a plasma emission spectrometry for elemental analysis have been determined. It allowed to start batch production of microwave plasma spectrometers. Realized MP-AES method supplements other widely used optical spectroscopic methods of elemental analysis - AAS and ICP-OES, and, moreover, has a number of unique advantages.

Electrical Fragmentation – a novel route for the refinement of quartz raw materials for trace mineral impurities The solar power actively develops around the world. For industrial production of solar batteries is very important the quality of raw materials so-called solar silicon. In this article the methods of refinement of quartz from the impurity to achieve the high purity of silicon for the solar cell Si-production are discussed. We evaluate and compare the comminution effects of electrical fragmentation and mechanical crushing. The possibility to combine both comminution techniques to receiving high-pure solar silicon with the minimum expenses is also discussed. The morphology of the particles, the crack distribution, and the degree of mineral liberation are studied by optical microscopy, electron probe micro-analyzer (EPMA), and X-ray diffraction (XRD).

Образование – не значит знание. О качестве подготовки специалистов в области аналитической химии
Не секрет, что российские вузы переживают сейчас не лучшие дни. Особенно тяжко приходится институтам и университетам технического направления – помимо насущных задач по поиску финансирования и выживания им приходится "бежать со всех ног", чтобы не отстать от технического прогресса и стараться включать в учебную программу современную и актуальную на сегодня информацию.
Насколько хорошо подготовлены к работе на современном аналитическом оборудовании молодые специалисты? Какие меры нужно предпринять, чтобы улучшить качество образования?
