The coherent body of research described in this book is concerned with new HPLC method development and validation using novel systematic approaches for pharmaceutical and diagnostic compounds. The first stage of the research was to study how analytical method development and validation are typically carried out at present and to formulate this into a simple step-by-step approach. Such a template and protocol was not only used as the foundation of this research programme but could also serve as a simple systematic guide for other practitioners and those new to the field. Furthermore, it was recognised that this protocol should satisfy the requirements of the most strategically important regulatory agencies. The second stage of this research involved evaluation and application of the above validation approach to new methods that were developed for a diverse range of analytes using HPLC and LC-MS. In essence, the critical review of the requirements for method validation for various agencies and the subsequent preparation of guidelines on how to go about method validation have had a significant impact on analytical practitioners worldwide.

Combined liquid chromatography-mass spectrometry has a long history of promises and breakthroughs. Many interfaces have been developed and commercialized over the past 25 years. Most of these have subsequently disappeared again, because of apparent problems, e.g. moving belt, direct liquid introduction, and thermospray. In the past few years, a real breakthrough has been made and years of promises are redeemed. Interfaces applied in combination with atmospheric-pressure chemical ionization have changed LC-MS, especially with respect to ease of operation, robustness, detection limits, and applicability ranges.LC-MS and related techniques have entered routine laboratories within pharmaceutical industries and related contract research institutes, laboratories concerned with biochemistry, biotechnology, environmental analysis, natural product research, and many other areas. Furthermore, other mass analysers than linear (triple) quadrupole instruments have found extensive use. From this perspective, the editors have invited authors both from fundamental, innovative instrumental and application-oriented research groups to contribute papers to this special issue on Current Practice of LC-MS. All of these papers, both review and research contributions, were peer-reviewed in the usual way. The result is a clear perspective on the current practice of LC-MS, as well as on new instrumental developments taking place.

The coherent body of research described in the existing published work is concerned with new assay method development and validation using novel systematic approaches for pharmaceutical and diagnostic compounds. The first stage of the research was to study how analytical method development and validation are typically carried out at present and to formulate this into a simple step-by-step approach. Such a template and protocol was not only used as the foundation of this research programme but could also serve as a simple systematic guide for other practitioners and those new to the field. Furthermore, it was recognised that this protocol should satisfy the requirements of the most strategically important regulatory agencies. The second stage of this research involved evaluation and application of the above validation approach to new methods that were developed for a diverse range of analytes and samples. A new purity assay for 1,10-phenanthroline-5,6- dione and 4,7-phenanthroline-5,6-dione using high-performance liquid chromatography (HPLC) was developed and validated. Impurities in these compounds were identified by liquid chromatography-mass spectrometry (LCMS). Best practice in method development and validation is equally important in the analysis of both active components and excipients in formulated products. In the first case, a liquid chromatography assay method for determining the content of 2-(diethylamino)-N-(2,6-dimethylphenyl) acetamide in a gel formulation was developed and validated. In the second case, the individual contents of three phydroxy benzoic acid ester preservatives in a complex multi-component sample were determined following the development and validation of a liquid chromatography method. Finally, the validation approach was evaluated as applied to another analytical technique. Here, gas chromatography (GC) successfully used to develop a novel assay for p-cymene in tea tree oil formulations presented different analytical problems because of the very complex nature of this natural product. Stability study information to increase the shelf life of the product and validation data for the analytical method for p-cymene content was critically evaluated. iv In essence, the critical review of the requirements for method validation for various agencies and the subsequent preparation of guidelines on how to go about method validation have had a significant impact on how analytical practitioners worldwide go about method development and, more importantly, method validation. Further it was possible to apply these guidelines to conduct a series of effective, successful method validation for assays involving a range of typical pharmaceutical samples.

Mass spectrometry coupled with liquid chromatography has been proven to be a powerful platform for essential testing for patients in clinical laboratories. It offers numerous advantages over traditional immunoassays to better serve patient needs. However, there are many challenges in implementing this technology and gaining wide applications in clinical practices. Major reasons are lack of systematic training and lack of understanding of the technology by medical technologists and laboratory scientists. Mass spectrometry analyses are relatively complex, labor intensive and often involve manual processes. Successful implementation of the technology in a clinical laboratory requires a deep understanding of mass spectrometry. It also requires sufficient troubleshooting knowledge for routine operations. In addition, majority of the assays are laboratory developed tests, which require in-depth understanding of the technology as well as regulations to successfully develop and implement new assays in the clinical laboratories. This book discusses practical applications of clinical mass spectrometry covering topics from its implementation in the lab, routine maintenance and troubleshooting, to assay development, validation, maintenance, and to regulatory considerations. LC-MS/MS is a hands-on technology. Its manual process nature highlights the challenges on daily operations. Given the increasing demand for mass spectrometry in the clinical laboratory and the lack of trained technologists and laboratory scientists at all levels to operate, maintain, and develop methods for those instruments, this book is intended to be a practical guide for clinical mass spectrometry. Furthermore, this book provides step-by-step instructions on how to develop and validate an assay. Practical Guide to Implementing Liquid Chromatography Mass Spectrometry in Clinical Laboratories is a valuable resource for clinical laboratories that implement mass spectrometry into their practice. It serves a reference for medical technologists and clinical laboratory scientists to gain practical guidance on how to best utilize the clinical mass spectrometry platform to best serve patient needs.
