Frontiers
Methods under real constraint.
Difficult samples and environments reveal which parts of an analytical workflow are genuinely robust—and which were being protected by the laboratory.
Four paths
Follow the constraint.
SCI includes frontier work when the separation, sample handling, or detection problem is central. These are editorial paths, not claims that every adjacent paper belongs.
Life science
Separation science resolves biological mixtures into evidence—from nucleic-acid sizing and protein charge heterogeneity to metabolites, particles, cells, and low-volume assays.
→ 02 · previewEnvironment and ocean
Environmental and ocean analysis connects representative sampling, changing matrices, preconcentration, in-situ measurement, and long-duration operation outside controlled laboratories.
→ 03 · previewSpace and planetary analysis
Planetary instruments must extract defensible chemical evidence under severe limits on mass, power, autonomy, contamination control, consumables, and sample handling.
→ 04 · previewPortable and miniaturized analysis
A credible portable analyzer must carry the workflow—not just a small instrument—through sampling, calibration, operation, quality control, data, consumables, and waste.
