Download or read book Measuring Heavy Metal Contaminants in Cannabis and Hemp written by Robert J. Thomas and published by CRC Press. This book was released on 2020-09-29 with total page 527 pages. Available in PDF, EPUB and Kindle. Book excerpt: The surge of interest in cannabis-based medicinal products has put an extremely high demand on testing capabilities, particularly for contaminants such as heavy metals, which are naturally taken up through the roots of the plants from the soil, growing medium, and fertilizers but can also be negatively impacted by the grinding equipment and extraction/distillation process. Unfortunately, many state regulators do not have the necessary experience and background to fully understand all the safety and toxicological issues regarding the cultivation and production of cannabis and hemp products on the market today. Measuring Heavy Metal Contaminants in Cannabis and Hemp offers a comprehensive guide to the entire cannabis industry for measuring elemental contaminants in cannabis and hemp. For testing labs, it describes fundamental principles and practical capabilities of ICP-MS and other AS techniques for measuring heavy metals in cannabis. For state regulators, it compares maximum contaminant limits of heavy metals with those for federally regulated pharmaceutical materials. For cultivators and processors, it helps them to better understand the many sources of heavy metals in cannabis. And for consumers of medical cannabis, it highlights the importance of choosing cannabis products that are safe to use. Other key topics include: The role of other analytical techniques for the comprehensive testing of cannabis products Tips to optimize analytical procedures to ensure the highest quality data Guidance on how to characterize elemental contaminants in vaping liquids and aerosols Suggestions on how to reduce errors using plasma spectrochemistry The role of certified reference materials to validate standard methods Easy-to-read sections on instrumental hardware components, calibration and measurement protocols, typical interferences, routine maintenance, and troubleshooting procedures Written with the cannabis testing community in mind, this book is also an invaluable resource for growers, cultivators, processors, testers, regulators, and even consumers who are interested in learning more about the potential dangers of heavy metal contaminants in cannabis and hemp.
Download or read book Practical Guide to ICP MS written by Robert Thomas and published by CRC Press. This book was released on 2013-04-25 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written by a field insider with over 20 years experience in product development, application support, and field marketing for an ICP-MS manufacturer, the third edition of Practical Guide to ICP-MS: A Tutorial for Beginners provides an updated reference that was written specifically with the novice in mind. It presents a compelling story about ICP-MS and what it has to offer, showing this powerful ultra trace-element technique in the way it was intended—a practical solution to real-world problems. New to the third edition: New chapter: Emerging ICP-MS Application Areas – covers the three most rapidly growing areas: analysis of flue gas desulfurization wastewaters, fully automated analysis of seawater samples using online chemistry procedures, and characterization of engineered nanoparticles Discussion of all the new technology commercialized since the second edition. An updated glossary of terms with more than 100 new entries Examination of nonstandard sampling accessories, which are important for enhancing the practical capabilities of ICP-MS Insight into additional applications in the environmental, clinical/biomedical, and food chemistry fields as well as new directives from the United States Pharmacopeia (USP) on determining impurities in pharmaceuticals and dietary supplements using Chapters 232, 233 and 2232 Description of the most important analytical factors for selecting an ICP-MS system, taking into consideration more recent application demands This reference describes the principles and application benefits of ICP-MS in a clear manner for laboratory managers, analytical chemists, and technicians who have limited knowledge of the technique. In addition, it offers much-needed guidance on how best to evaluate capabilities and compare with other trace element techniques when looking to purchase commercial ICP-MS instrumentation.

Download or read book Measuring Elemental Impurities in Pharmaceuticals written by Robert Thomas and published by CRC Press. This book was released on 2018-01-29 with total page 457 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent regulations on heavy metal testing have required the pharmaceutical industry to monitor a suite of elemental impurities in pharmaceutical raw materials, drug products and dietary supplements. These new directives s are described in the new United States Pharmacopeia (USP) Chapters , , and , together with Q3D, Step 4 guidelines for elemental impurities, drafted by the ICH (International Conference on Harmonization of Technical Requirements for Registration of Pharmaceuticals for Human Use), a consortium of global pharmaceutical associations, including the European Pharmacopeia (Ph.Eur.), the Japanese Pharmacopeia (JP) and the USP. This book provides a complete guide to the analytical methodology, instrumental techniques and sample preparation procedures used for measuring elemental impurities in pharmaceutical and nutraceutical materials. It offers readers the tools to better understand plasma spectrochemistry to optimize detection capability for the full suite of elemental PDE (Permitted Daily Exposure) levels in the various drug delivery categories. Other relevant information covered in the book includes: The complete guide to measuring elemental impurities in pharmaceutical and nutraceutical materials. Covers heavy metals testing in the pharmaceutical industry from an historical perspective. Gives an overview of current USP Chapters and and ICH Q3D Step 4 Guidelines. Explains the purpose of validation protocols used in Chapter , including how J-values are calculated Describes fundamental principles and practical capabilities of ICP-MS and ICP-OES. Offers guidelines about the optimum strategy for risk assessment Provides tips on how best to prepare and present your data for regulatory inspection. An indispensable resource, the fundamental principles and practical benefits of ICP-OES and ICP-MS are covered in a reader-friendly format that a novice, who is carrying out elemental impurities testing in the pharmaceutical and nutraceutical communities, will find easy to understand.
