Sample PreparationICP-MS results depend on clean, representative, matrix-appropriate sample preparation. This guide reviews practical preparation choices, QC checks, and common risks in trace element analysis.
Sample PreparationA practical guide to FTIR spectroscopy sample preparation for ATR, KBr pellets, liquids, films, gases, powders, and routine troubleshooting.
Sample PreparationA practical guide to preparing protein samples for western blot analysis, covering lysis, clarification, protein quantification, denaturation, loading, and error prevention before electrophoresis begins.
Sample PreparationXPS sample preparation determines whether a spectrum reflects the intended surface or a layer of contamination, oxidation, loose powder or mounting material. This guide explains practical preparation choices…
Sample PreparationCryo TEM sample preparation converts a hydrated specimen into a thin, vitrified grid for imaging without conventional drying or staining. This article reviews the workflow, key variables, common…
Sample PreparationGC MS sample preparation determines whether volatile and semi-volatile analytes reach the instrument cleanly, reproducibly and at a measurable level. This guide compares common preparation options, quality controls…
Sample PreparationA practical guide to gas chromatography sample preparation workflows for VOCs, semi-volatiles, residues, oils, and complex matrices, including headspace, purge-and-trap, extraction, SPME, derivatization, cleanup, and quality-control decisions.
Sample PreparationElectron microscopy sample preparation determines whether TEM and SEM images show the specimen’s structure or artifacts introduced during handling. This article compares biological, materials, cryogenic, particle, and quality-control…
Sample PreparationReliable powder XRD depends as much on the specimen as on the diffractometer. This guide explains how grinding, mounting geometry and documentation affect X-ray diffraction sample preparation.
