LCGC App of the Month CEToolbox

A machine-learning tool to enhance the detection of small organic pollutants in water has been developed and tested.

Peter 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.

A recent study aimed to investigate the impact of lavender essential oil (LEO) and of its terpenic components on the properties of glioblastoma (GBM) cells in an in vitro model. The study demonstrated that LEO induces a proliferation slowdown and an impairment of cell migration of GBM cells besides reducing oxidative stress.

University of Valencia scientists recently developed a method using solid-phase extraction (SPE) followed by high-performance liquid chromatography coupled to high-resolution mass spectrometry (HPLC–HRMS/MS) for detecting microplastics and other harmful substances in textiles.
