This interview explores how high school students learn separation science through filtration, gravimetric analysis, and chromatography, building the foundations for future chemistry studies.

Integrating GC-O with GC×GC enables a direct link between chemical data and sensory perception. Sample enrichment, two-dimensional separation, and chemometrics improve aroma analysis.

ICP-OES and GC×GC-TOFMS compare new vs. used aircraft oils. Results show >20% phosphorus loss in jet oils and strong lead accumulation in piston oils—highlighting potential cabin-air and handling risks.

GC×GC-HRTOFMS enables fast and reliable screening of PFAS and emerging contaminants in complex consumer goods, combining EI/PCI/NCI and mass defect workflows for confident identification.

GC×GC-TOFMS reveals how yeast strain and honey concentration shape mead aroma. Learn the workflow from headspace sampling to PCA/PCoA/HCA, plus key VOC trends across fermentations.

Advanced chemometric methods reveal subtle, statistically significant changes in complex GC×GC-MS and LC-MS data. Learn how Alteration Analysis and 2D correlation turn massive datasets into actionable insights.

FMT therapy relies on living microbes—and metabolomics helps prove quality. In this interview, Ryland explains GC×GC-TOFMS, SPME sample prep, and why data skills matter.

Interview with Dr. Eamonn Clark on WRRC water research, fuel-spill impacts, PFAS workflows, and how DIY tools like a homebuilt nitrogen evaporator can expand low-resource labs.

Jim Averso explains why syringe filtration is critical for chromatography, how to choose membranes and pore sizes, avoid common mistakes, cut backpressure, and streamline sample prep with prefiltration.

KnowItAll 2026.1 maintenance release brings LC-MS deconvolution improvements, updated DEA rulebases, and bug fixes to enhance spectral analysis workflows and performance.
