Restek’s new Rezin certified clean SDVB resin is an exceptionally clean SDVB resin for semi-volatile organic compound (SVOC) sampling. Specifically developed for use straight from the bottle, many applications will not require any further cleaning, eliminating the need for labs to perform this costly, time-consuming step.
A new proprietary cleaning method—designed by Restek’s expert chemists—has produced a resin with exceptionally low background levels of contaminants, including PAHs, pesticides, PCBs, dioxins, and PFAS. Rezin adsorbent is below the allowable residual PAH levels in EPA method TO-13 and is certified to show it surpasses these method requirements.
Additionally, Rezin certified clean SDVB resin (cat.# 27242) is sieved and homogenized prior to packaging, producing a free-flowing resin that can easily be extracted from the container without any messy clumping.

The Next Frontier for Mass Spec: Maximizing Ion Utilization
January 20th 2025MOBILion has introduced a new high-resolution mass spectrometry (HRMS) approach that can increase speed and sensitivity in omics applications. The parallel accumulation with mobility aligned fragmentation (PAMAF) approach substantially increases the fraction of ions used for MS analysis by replacing the functionality of the quadrupole with high-resolution ion mobility.
The Intricacies 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.
