Food and beverage manufacturers who perform simple sugar analysis require methods that provide sensitive, selective, and direct determination of carbohydrates. Minimizing errors associated with sample preparation is of key importance, because samples often require large dilutions that can impact the downstream accuracy of results. In this summary, the benefits of using high-performance anion-exchange chromatography coupled with pulsed amperometric detection (HPAE-PAD), which does not require sample derivatization, will be discussed. We will also cover recent technological advances, including high pressure ion chromatography, which have enabled manufacturers to analyze more samples in less time.

While conventional calibration for gel permeation (GPC) or size-exclusion chromatography (SEC) is useful, there are inherent disadvantages in this type of analysis that introduce experimental error. This uncertainty may cast serious aspersions on the rigour and utility of the results. Multi-angle light scattering (MALS) detection is quite simple to add to an existing chromatography system and can help overcome the challenges faced with single detector chromatography and conventional calibration-based methods. An alternative separation technique called asymmetric flow field-flow fractionation (AF4) offers tunable, column-free fractionation.

The third instalment in this series provides an overview of modern practices of separation science in small-molecule drug development. It highlights approaches in high performance liquid chromatography (HPLC) method development and physical or chemical characterization to support process chemistry and formulation development, and for assessment or control of clinical trial materials. The roles of separation scientists in analytical development and salient chromatographic methodology trends are also discussed.

Monoclonal antibody (mAb) treatment is among the most effective method of diagnosis and treatment of a broad range of diseases, including autoimmune disorders, cardiovascular diseases, infectious diseases, cancer, and inflammation. There is an extensive development pipeline for protein and mAb therapeutics, emphasizing the need for innovative and efficient analytical tools that result in faster analysis times. This article explores the use of supermacroporous particles for the analysis of mAbs.
