How can you extend GC column lifetime and prevent contamination? Part 2 focuses on using liners with glass wool and proper column bake-out to maintain separation performance.

Dirty samples can quickly damage your GC column and shorten its lifetime. Learn simple, proven ways to protect your column, improve performance, and reduce downtime. Part 1 focuses on smart sample preparation.

Eurachem/CITAC VaMPIS guidance introduces validation of measurement procedures that include sampling, using measurement uncertainty to assess fitness for purpose in both in situ and ex situ measurements.

An SPE technical tip focused on identifying the sources of interferences and extra peaks observed after sample extraction.

Although 100% recovery is expected in SPE, values above 100% are sometimes observed. This article explains the most common causes and provides practical guidance on how to identify and resolve them.

A technical guide to troubleshooting low analyte recovery in SPE. Explains relative vs. absolute recovery and provides practical solutions for conditioning, loading, and sorbent selection.

How can neutral analytes be efficiently concentrated in the presence of ionized acidic or basic contaminants? This SPE tip explains how mixed-mode cartridges improve selectivity and cleanup.

A clear guide to Normal Phase SPE: when to use it, how polar interactions drive retention, and which solvents to choose in increasing polarity—plus a quick reference list for optimized sample preparation.

GC performance often declines due to worn or contaminated inlet parts. Regular replacement of liners, septa, and key components reduces failures, prevents downtime, and keeps results consistent.

A clear guide to GC column temperature limits: how maximum and minimum temperatures affect stability, when damage occurs, and how high-temperature Zebron columns extend performance for demanding analyses.
