Pall product profile
Increase column life and improve chromatographic results with Pall Life Sciences’ newest 0.2 µm Acrodisc® syringe filter for Ultra High Performance Liquid Chromatography (UHPLC) sample prep filtration. Available in 13 and 25 mm sizes, the UHPLC filter is ideal for UHPLC sample prep and buffer filtration when using column packings < 2 µm. The syringe filter’s GxF multi-layer prefilter provides two to four times more throughput than standard glass fiber prefilter devices, allowing quick and easy filtration of difficult-to-filter solutions. The new 0.2 µm filters are available with nylon, GHP, PTFE, and PVDF membranes, and are HPLC certified for low levels of UV absorbing extractables for less interference in chromatographic results. Applications include sample prep for UHPLC, sample prep for microbore columns, and those where microbial growth is a concern.

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.
Metabolomics Analysis of Low Birth-Weight Infants Using UHPLC-MS/MS Following Lipid Emulsion
January 10th 2025A recent study aimed to directly compare the changes in serum metabolites among very low birth-rate (VLBW) infants following the administration of the soybean oil-based lipid emulsion and soybean oil, medium-chain triglycerides, olive oil, and fish oil (SMOF) lipid emulsion using untargeted metabolomics techniques.
