Current Trends in Chiral Separations

Articles

The HPLC symposium series is recognized as “the forum” where new developments in liquid phase separations and their hyphenation to mass spectrometry (MS) for the analysis of (bio)pharmaceutical compounds and their metabolites are presented.

Contemporary Trends in Biopharmaceutical Analysis

This is the second in a series of articles exploring current topics in separation science that will be addressed at the HPLC 2017 conference in Prague, Czech Republic, from 18–22 June.

HPLC 2017 Topic Preview: Contemporary Trends in Biopharmaceutical Analysis

Ion chromatography coupled to mass spectrometry (IC-MS) does not follow the same rules as coupling other modes of liquid chromatography to mass spectrometry (LC–MS). Leon Barron from the Analytical & Environmental Science Division, at King’s College London, UK, reveals some of the misconceptions surrounding IC and discusses contemporary trends and novel applications for this inventive technique.

Contemporary Trends in Ion Chromatography

In recent years, food analysis has blossomed out from a singular focus on food safety to a studies of a wide array of questions such as the authentication of food origin and the nutritional aspects of natural food compounds. In this new e-book, we explore some current trends in food analysis and also provide some concrete advice for preparing food samples for analysis.

Leading separation scientists discuss their approaches to improving the analysis of large molecules.

Trends in Separation Science: Tackling Protein Analysis

Structural, bioanalytical, characterization, and quality control studies are critical for successful drug development. These studies must be as accurate, sensitive, and selective as possible, and liquid chromatography coupled to tandem mass spectrometry (LC–MS–MS) has been the technique of choice for many areas of small molecule analysis for the past 30 years. During that time, rapid improvements in analytical technologies have supported the development of more sensitive and robust methods. However, the pharma and biopharma industry continues to need more powerful instruments and more diverse methods, particularly as therapeutics have expanded to include large molecules. This work follows on from an earlier article that explored the limitations of LC–MS–MS for bioanalysis of biologics. This article considers some of the current issues for analysis of small and large molecules, and emerging trends in method development.

Trends and Challenges for Bioanalysis and Characterization of Small and Large Molecule Drugs

The results obtained from a new survey on sample preparation techniques were compared with the results of previous surveys from 1991 to March 2013. The survey investigated trends in technologies currently being used, sample loads, sample sizes, automation, the use of solid-phase extraction (SPE) devices (cartridges, disks, plates, tips), SPE chemistries, selection criteria, and problems encountered. Respondents were also asked about sample preparation technologies on the horizon.

Trends in Sample Preparation

This instalment of “Sample Preparation Perspectives” compares the results obtained from a new survey on sample preparation techniques with the results of previous surveys from 1991 to March 2013. The survey investigated trends in areas such as technologies currently being used, sample loads, sample sizes, automation, the use of solid-phase extraction (SPE) devices (cartridges, disks, plates, tips), SPE chemistries, selection criteria, and problems encountered. Respondents were also asked about sample preparation technologies on the horizon.
