This book was released on 2009 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two sample preparation techniques, low-temperature cleanup and sweep co-distillation, which are simple, fast, inexpensive and using small amount of organic solvent have been developed for the determination of 16 polycyclic aromatic hydrocarbons (PAHs) in refined and used cooking oil samples by high-performance liquid chromatography with fluorescence detection (HPLC-FLD). For low-temperature cleanup method, freezing time, extraction solvent, number of extraction and SPE cleanup affected the extraction efficiency. Optimum extraction was achieved when using a mixture of acetonitrile and acetone (80:20, v/v) as extraction solvent, freezing between -18 oC to -25 oC for 24 hours twice and cleanup with alumina N SPE cartridge. This method was effectively determined all 16 PAHs. The recoveries were 45.88 - 118.47%. Limit of detections (LODs) and limit of quantitations (LOQs) were 0.13 to 3.13 ng/g and 0.25 to 6.25 ng/g, respectively. In sweep co-distillation method, distillation temperature and time had an effect on the extraction efficiency. Optimum extraction was attained when distillated at 235 oC for 60 minutes. However, this method was quantitatively analyzed only 8 PAHs. The recoveries were 47.48 - 119.47%. LODs and LOQs values were about two times higher than low-temperature cleanup method. Finally, both methods were successfully tested for determination of PAHs in reference materials of olive oil (RM FAPAS T0631) and real cooking oil samples.

Download or read book HPLC written by Joel K. Swadesh and published by CRC Press. This book was released on 1996-11-26 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: High performance liquid chromatography (HPLC) is a technique used in diverse laboratory and industrial settings for the separation of components of complex mixtures. HPLC: Practical and Industrial Applications is a trouble-shooting, problem-solving guide for scientists, engineers, and technicians who use HPLC in their day-to-day work. It provides the answers to specific problems and includes practical case studies. This case history approach to chromatography is an effective teaching tool and clearly illustrates how to use techniques such as reversed phase chromatography, ion exchange chromatography, gel permeation chromatography, and capillary electrophoresis. The book is organized to facilitate rapid understanding for those working with a particular area of chromatography: Introduces the reader to instrumentation, reviews basic chromatographic theory, and presents a brief survey of absorbance fluorescence and refractive index detectors. Provides a broad view of the role of the analytical laboratory in an industrial organization. Offers suggestions on optimizing the utilization of personnel and work flow in the laboratory. Covers process sampling and analysis · Describes process chromatography. The remaining chapters discuss specialties within separations technology, including an outline of the key features of each technique, a thorough bibliography, a list of precedents, and detailed examples of one or more applications presented from the viewpoint of industrial and basic scientists. Specialty detectors are also described. HPLC: Practical and Industrial Applications is an essential reference for those working in the industrial sector, as well as scientists, students, technicians interested in learning HPLC methods.

Available in PDF, EPUB and Kindle. Book excerpt: The introduction of combinatorial chemistry technology has increased the amount of compounds generated in a year from 50 to 2000. Conventional analytical approaches simply cannot keep up. These circumstances have caused drug discovery to take on the shape of a bottleneck, like traffic through a toll booth. In order to break the bottleneck, a corres
