Water and Its Impurities
most versatile and sensitive tools for micro-chemical studies of biological material. Since the publication of Volume I, which covers this topic very briefly, many advances have been made both in the development of new procedures and in the adaptation of existing ones to the micro-chemical level. Although the latter deficit is recognized by Dr. Glick in the preface to Volume II, it is unfortuna...
متن کاملImpurities and Its Importance in Pharmacy
The current practice of characterization and control of impurities in pharmaceutical substances and products are reviewed with emphasis on issues specific to the active pharmaceutical ingredient and pharmaceutical formulations. The control of pharmaceutical impurities in the pharmaceutical industry is an important task to the formulator. The International Conference on Harmonization (ICH) has f...
متن کاملOptical Opacity of Laser Induced Plasma in Distilled Water with NaCl and TiO2 Nanoparticles Impurities
In this paper, the dynamic behavior of laser induced optical breakdown in impure water was studied by using a pump- probe technique. The plasma was induced by a 1064 nm Nd:YAG laser pulse (with pulse duration ~10 ns) in distilled water with two types of impurities: (I) a solution (highly diluted salt water as a conductor) and (II) a colloidal (TiO2 in colloidal nanoparticle form as a dielectric...
متن کاملNew developments in the characterization of heparin and its impurities
This special issue highlights many aspects of heparin characterization. Heparin, a glycosaminoglycan, is both an important pharmaceutical in it is own right and a pharmaceutical target for drug discovery as it mediates a wide range of biological processes. A potent anticoagulant isolated from porcine intestinal mucosa, approximately one billion pigs a year are required to constitute the heparin...
متن کاملRapid liquid chromatographic determination of itraconazole and its production impurities.
A simple, rapid ultra-performance liquid chromatography (UPLC) method was developed for the analysis of itraconazole and its associated production impurities. The optimum chromatographic conditions were achieved using an Agilent Zorbax Eclipse XDB C18 column, 1.8 µm (4.6 × 50 mm) installed in a column oven heater utilizing a gradient mobile phase of 0.08M tetrabutylammonium hydrogen sulfate buf...
