Pharmaceutical Analysis

The Column spoke to Brett Paull from the University of Tasmania in Hobart, Australia, about the development of truly portable LC systems for use in the pharmaceutical industry and in environmental analysis. Why are they necessary, and where can improvements still be made?

This case study of the career path of a separation scientist illustrates the diversified roles of an analytical chemist in nonclinical drug development.

This simple, rapid, and accurate HPLC-UV method can facilitate routine therapeutic drug monitoring in neonates.

Barry L. Karger and James P. Grinias are the winners of the 15th annual LCGC Lifetime Achievement and Emerging Leader in Chromatography Awards, respectively, for 2022. Here, we review their achievements.

Compact instrumentation offers important advantages for many workflows, as illustrated by these examples.

This novel gas chromatography (GC)–MS approach enables analysis of the suspected mutagens bis(pinacolato)diboron (BPD) and tetrahydroxydiboron (BBA) found at low-levels in certain intermediates and active pharmaceutical ingredients (APIs), even in the presence of boron from other sources.

Here, a new automated active pharmaceutical ingredient (API) extraction platform is integrated with online liquid chromatography (LC) to assess drug product potency. The platform dissolves the tablet coating (if present), disintegrates the tablet, and disperses and solubilizes the tablet for analysis.

This concise yet comprehensive overview of sample preparation for bioanalysis looks at sample preparation fundamentals, best practices, and modern trends—all illustrated with a case study.

This article discusses the development of a series of applications that will allow for the determination of a number of nitrosamines that have been identified by the FDA as genotoxins to monitor, initially showing how to perform a separation of these compounds from the API and then looking at how MS can be applied to the analysis to ensure that the required detection limits can be reached.

This is the first article in a four-part series exploring the quantitative assessment of drugs and their metabolites in biological fluids (such as blood, plasma, and urine) and tissue homogenates using liquid chromatography–mass spectrometry (LC–MS).

We assess recent advances in cleaning verification methods for small-molecule pharmaceuticals, and propose a workflow.

Is there a secret formula to getting hired into a pharmaceutical analytical chemistry group? What skills are prized above all others?

Ion-exchange chromatography (IEX) is a frequently overlooked technique. This novel IEX method uses non-aqueous mobile phases to purify a non-crystalline intermediate after a reductive amination with D-xylose. IEX delivers a step change in strength and purity of the intermediate allowing successful downstream processing.

Drug substance development requires a range of analytical methods to be developed to generate process knowledge and to support in-process and release testing throughout a synthetic sequence. This article describes practical examples of a wide variety of transfer challenges and our remediation strategy.

This Friday morning session honors the 2021 LCGC award winners: Paul Haddad of the University of Tasmania, and the foundation director of the Australian Centre for Research on Separation Science (ACROSS); and Erik L. Regalado, of the pharmaceutical company Merck & Co.

The COVID-19 vaccine, and the speed at which it was developed, is the medical breakthrough of our lifetimes.

Incognito leads us through the complex method used to determine related substances for hydroxychloroquine, exploring the practical implementation and critical evaluation of a less than optimum ultrahigh-pressure liquid chromatography (UHPLC) pharmacopeial method.

In the pharmaceutical industry, method validation is essential. But what are the best practices? We review regulatory requirements, validation parameters, methodologies, acceptance criteria, trends, and software tools.

Here we provide an overview of the fundamentals and best practices on the development of stability-indicating HPLC methods for drug substances and products. We explain both traditional and easier modern approaches to developing stability-indicating HPLC methods—including using a universal generic method for new chemical entities—and address regulatory considerations and life cycle management strategies.

Determining product shelf life is a regulatory requirement for pharmaceuticals and many other regulated consumer products. In this comprehensive overview of stability studies and testing, we summarize current regulatory requirements, share industry practices for forced degradation, and explain approaches for reduced testing and data evaluation to expedite stability study timelines.

A fast ultrahigh-pressure liquid chromatography (UHPLC) method, with low solvent consumption, is described for the determination of coenzyme Q10 in a variety of complex formulations. This method exhibits good linearity, reproducibility, accuracy, recovery, and specificity, while resulting in an acceptable limit of detection (LOD) and limit of quantification (LOQ).

This article will discuss the benefits of 2D-LC and multiple application areas in (bio)pharmaceutical analysis, and will highlight the challenges and future outlook.

This article presents possible uses of ion chromatography and related techniques combined with various detection methods for clinical and pharmaceutical analysis of common inorganic and organic anions and cations. An overview of achievements in this area from the past 10 years is presented and the most important trends and development perspectives for ion chromatography are described.

The main objective of this review article is to provide a clear summary of the different methods that can be used to quantify endogenous small molecules. Because of the increased use of mass spectrometry (MS) in the field of bioanalysis, a special focus will be placed on quantification by liquid chromatography (LC)–MS. Practical recommendations to face this bioanalytical challenge, in particular in terms of method validation, will also be provided.
