Planar chromatography e-book
A website, which is an internet-based planar chromatography (PLC) book, has been created by Professor Rudolf E. Kaiser. The author, using 50 years of his own experiences in planar chromatography as well as discussions with more than 5000 colleagues from more than 55 countries, considers the steps needed to solve problems using PLC. The site discusses a range of techniques including TLC, HPTLC, OPLC and HPPLC as well as what it claims to be a 'truly planar' technique μ-PLC (micro planar liquid chromatography). What 'truly planar' means is considered, as well as the technique's implications. The history of various related techniques are given and a consideration of circular versus linear modes provide a background on the subject. Pictograms, methods and applications cover the use of the technique and a do-it-yourself guide is included to assist users in the construction of their own instrument.

Web-based dashboard
Waters has announced it is now shipping its Empower 2 Business Intelligence Manager, a web-based dashboard software solution that is reported to provide rapid analysis of critical chromatography performance data for faster, more-qualified decisions on laboratory and business operations. According to the company the intuitive interface allows lab managers and system administrators using Empower 2 Enterprise Chromatography Software to fully understand and exploit the strengths of their laboratories and identify areas that need added support.
On-demand webinars
Wyatt Technology has announced the introduction of a programme of free-of-charge, on-demand webinars about light scattering and related technologies. Designed to meet the increasing demand for scientific training on macromolecular characterization instrumentation, the on-line webinar series is reported to provide comprehensive information about the company's light-scattering products and services. Current webinars are available on high-throughput automated dynamic light scattering using the DynaPro Plate Reader, characterizing protein–protein interactions with static light scattering and the Calypso automated protein association and aggregation system, characterizing protein conjugates and their aggregates by light scattering and field flow fractionation combined with multi-angle light scattering.
Streamline syringe selection
Hamilton has announced the release of a web-based syringe Selection Tool. According to the company it features a filtering function that helps users quickly identify the exact syringe, with part number, to fit their application. The tool filters decision characteristics and narrows searches from among the company's 794 different syringes. Seven pull-down menus enable users to choose where to start their search from a choice of values — syringe type, volume, series number, termination, gauge, length or point style. The selection tool also presents more product details at the individual part number level, whereas information was previously displayed for families of products.

Chromatography software update
DataApex has released an update of its Clarity chromatography software. This version brings new control drivers covering Hitachi LaChrom Elite HPLC system (L-2100/2130 pump, L-2200 autosampler, L-2300 Column Oven, L-2400 UV Detector) and the latest HTA autosampler HT800L. According to the company the software can now control more than 250 instruments. This version enhances several functionalities that bring users more comfort during installation and configuration. The update is available for Clarity users free of charge.
The Next Frontier for Mass Spectrometry: Maximizing Ion Utilization
January 20th 2025In this podcast, Daniel DeBord, CTO of MOBILion Systems, describes a new high resolution mass spectrometry approach that promises to increase speed and sensitivity in omics applications. MOBILion recently introduced the PAMAF mode of operation, which stands for parallel accumulation with mobility aligned fragmentation. It substantially increases the fraction of ions used for mass spectrometry analysis by replacing the functionality of the quadrupole with high resolution ion mobility. Listen to learn more about this exciting new development.
Measuring Vitamin D3 in Hen's Egg Yolk with HPLC
January 29th 2025Researchers have developed a method employing high performance liquid chromatography with ultraviolet detection (HPLC-UV) to determine vitamin D3 in food (even in the presence of vitamin D2, and with a specific focus on egg yolk) in a cost-effective and quantitative manner.
The Complexity of Oligonucleotide Separations
January 9th 2025Peter Pellegrinelli, Applications Specialist at Advanced Materials Technology (AMT) explains the complexity of oligonucleotide separations due to the unique chemical properties of these molecules. Issues such as varying length, sequence complexity, and hydrophilic-hydrophobic characteristics make efficient separations difficult. Separation scientists are addressing these challenges by modifying mobile phase compositions, using varying ion-pairing reagents, and exploring alternative separation modes like HILIC and ion-exchange chromatography. Due to these complexities, AMT has introduced the HALO® OLIGO column, which offers high-resolution, fast separations through its innovative Fused-Core® technology and high pH stability. Alongside explaining the new column, Peter looks to the future of these separations and what is next to come.
