Application Notes: General

Particularly in the pharmaceutical industry, drug purity isn’t just a goal – it’s essential for achieving safety, stability and efficacy. However, purification is easier said than done, especially with challenging molecules like DNA and RNA “oligonucleotides,” due in large part to their diversity and the range of impurities that can be generated during production. Enter DAVISIL® chromatographic silica, with a wide range of pore diameters and particle sizes to meet your specific application, performance and sustainability requirements. Before you choose the chromatography resin for your next purification application, take a look at these 5 considerations.

Recent advancements in automated protein purification stress the importance of efficiency, scalability, and yield consistency. This eBook compares different purification platforms, highlighting their impact on downstream applications and demonstrating how automation enhances throughput and process control.

As PFAS contamination spreads across the environment, advanced screening and characterization techniques are crucial for detection and risk assessment. This e-book explores cutting-edge analytical methods for identifying PFAS in environmental and biological samples.

The Axcend FocusArray is the ideal choice for your challenging liquid chromatography requirements. The only diode array detectr for capillary HPLC offers a full three orders of magnitude linearity needed to identify trace elements in the presence of your target analytes.

The Focus LC high-performance liquid chromatography (HPLC) system is small enough to be easily placed near the sample source and powerful enough to be used in any state-of-the-art laboratory. It’s optimized for low solvent consumption, waste reduction, and energy conservation, and delivers the performance and reliability you need for the highest confidence in your daily results.

Axcend InFocus™

InFocus enables real-time in-line sampling, ensuring process integrity throughout the workflow, including inside a hood or next to a reaction vessel. Scientific breakthroughs and process optimizations require fast, accurate, and reliable data. As a Process Analytical Technology (PAT) tool, the InFocus enables real-time, in-line, on-line, and at-line analysis, allowing scientists and engineers to detect inefficiencies, optimize reactions, and improve product quality without delays.

AutoFocus autosampler allows automated and unattended introduction of multiple standards and samples to the Axcend Focus LC for separation and analysis. The automated sampling system streamlines precision sample injection, improving efficiency and throughput. Designed for effortless operation and maintenance, AutoFocus offers excellent performance, making it the ideal autosampler for unattended analyses.

A full-stack capillary HPLC system, such as the one recently launched by Axcend, integrates several innovative features that set it apart from traditional HPLC systems. This compact system includes a 40-vial/96-well plate autosampler, an in-line process analytical technology (PAT) monitoring system, and a full-spectrum diode array detector (DAD). These components work together to enable real-time data analysis at the point of sampling, significantly enhancing productivity and precision. One of the most remarkable aspects of this system is its small footprint, which optimizes valuable lab and production space while reducing costs and environmental impact (the base measures 13" X 9"). The low-flow design minimizes solvent consumption and hazardous waste, aligning with sustainable laboratory practices. Additionally, the system's ability to perform HPLC anywhere—whether inside a hood or next to a reaction vessel—provides unparalleled flexibility for scientists.

Pittcon took place from March 1 to 5, 2025, in Boston, Massachusetts. This premier event brought together professionals from various laboratory science disciplines to share research findings, discuss advancements, and collaborate on best practices. In this video interview, we speak with Katelynn Perrault Uptmor, Xiao Su, Chris Palmer, and Long Luo, all of whom attended Pittcon this year and delivered important talks that provide insight into the state of separation science.

The dream state If we lived in an ideal world, it would be possible to unambiguously identify metabolites using a single analytical experiment. This analytical technique would need to be efficient and easily generate the information needed from a routine assay that is also robust, enabling confident decision-making during drug discovery. At SCIEX, we believe that metabolite identification using the ZenoTOF 7600 system gets close to this dream state.

The diterpenoid, paclitaxel, which was identified as a potent chemotherapy agent for breast and ovarian cancer originates from the Pacific Yew tree. The isolation of paclitaxel from its major impurities is shown with the use of Hamilton’s PRP-1 (5 µm) HPLC column.

Lee Ferguson, a Professor of Civil and Environmental Engineering at Duke University, and his group are developing and applying analytical methods to measure organic pollutants in the environment, with a focus on high-resolution mass spectrometry (HRMS) for detecting and quantifying emerging contaminants in wastewater and drinking water. In this video interview, we speak with Ferguson about his laboratory’s work accurately tracing these contaminants in complex environmental matrices.
