Book excerpt: Analytical chemistry is playing a vital role in determination of various drugs and pharmaceutical products.The chemical features of selected drug molecules still offer a lot of scope for the development of new UV and visible spectrophotometric and HPCL methods hopefully with better sensitivity, selectiviy, precision and accuracy.The author has made some attempts in this direction and succeeded in developing some new methods having advantages of one or more of the desirable features.

This book was released on 2000-10-18 with total page 526 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spectrophotometry enables one to determine, with good precision and sensitivity, almost all the elements present in small and trace quantities of any material. The method is particularly useful in the determination of non-metals and allows the determination elements in a large range of concentrations (from single % to low ppm levels) in various materials. In Separation, Preconcentration and Spectrophotometry in Inorganic Analysis, much attention has been paid to separation and preconcentration methods, since they play an essential role in increasing the selectivity and sensitivity of spectrophotometric methods. Separation and preconcentration methods have also been utilised in other determination techniques. Spectrophotometric methods which are widely used for the determination of the elements in a large variety of inorganic materials are presented in the book whilst separation and preconcentration procedures combined with spectrophotometry are also described. This book contains recent advances in spectrophotometry, detailed discussion of the instrumentation, and the techniques and reagents used for spectrophotometric determination of elements in a wide range of materials as well as a detailed discussion of separation and preconcentration procedures that precede the spectrophotometric detection.

This book was released on 2013 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the present book some simple and sensitive spectrophotometric methods for determination of drugs in pharmaceutical formulations and in biological samples have been described. The methods are based on the use of chromogenic reagents, redox reactions, solvent extraction and solid phase extraction techniques. The methods for validation of developed methods have also been described. The drugs for which methods have been described are -methyldopa, sulphonamide derivatives, lamivudine, nimesulide, nicorandil, olanzapine, and phenothiazine derivatives."

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Characterization of turbid materials by determining their inherent optical properties have attracted strong research interest for potentially wide applications in fields such as material analysis and biomedical optics. The response of a homogeneous turbid sample to an optical excitation can be accurately described by absorption coefficient [mu]a, scattering coefficient [mu]s, and anisotropy factor g based on the radiative transfer theory. Existing spectrophotometric methods typically uses integrating spheres to acquire the light signals. These approaches, however, are difficult to be translated into instruments for users without special training. The research goal of this dissertation research project is two-fold: (1) Develop and validate a new spectrophotometric method without integrating sphere to characterize turbidity for optically thick samples by three optical parameters of [mu]a([lambda]), [mu]s([lambda]) and g([lambda]). (2) Demonstrate the applicability of the new spectrophotometric method as a label-free assay of cell suspension samples treated by a chemotherapy drug. An experimental system has been developed to measure signals of diffuse reflectance Rd, diffuse transmittance Td and forward transmittance Tf as functions of wavelength [lambda] between 460 and 1000nm from two types of samples. We have inversely determined the optical parameters of polystyrene microsphere samples by an in-house build individual photon Monte Carlo (iMC) simulation software. Validation of the new method has been achieved by comparing the optical parameters determined from the measured signals to those predicted by the Mie theory. In addition, we have applied the validated method to obtain the optical properties of MCF-7 cell samples treated by an apoptosis inducing drug doxorubicin for three different doses and three post-treatment times. By comparing to apoptosis measurement results of MTT assay and fluorescent flow cytometry, we were able to qualitatively demonstrate the potential applications of the new spectrophotometric method as a label-free assay to detect cellular apoptosis in treated samples.
