Designed for food safety labs analyzing these emerging compounds of interest, Restek’s new multi-component mix meets all compounds listed by AOAC SMPR 2019.004 and Commission Recommendation (EU) 2022/495. By combining eight furan and alkylfuran compounds into one ampul, calibration complexity is reduced, enabling labs to minimize errors, save time, and decrease costs.
A high concentration of 100 μg/mL adds additional flexibility in creating working standards, and an optimized SPME Arrows and GC-MS method helps labs streamline method development.
The Furan/Alkylfurans Standard (cat.# 33334) is a certified reference material (CRM) manufactured and QC-tested in Restek’s ISO-accredited labs.

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.
