Uses of GC and HPLC Columns
- Gas Chromatography (GC) Column Uses
GC columns are used to separate volatile and semi-volatile compounds in a variety of industries. These columns come in two main types: capillary columns (fused silica or metal) and packed columns (less common today).
Common Applications:
- Environmental Testing: VOCs, SVOCs, pesticides, PAHs
- Pharmaceuticals: Residual solvents (USP <467>), drug impurity profiling
- Petrochemicals: Hydrocarbon analysis, fuel purity, gas composition
- Food and Flavor Analysis: Aroma compounds, food preservatives
- Forensic Science: Drug and toxin identification
- Chemical Industry: Organic solvents, monomers, industrial gases
- HPLC Column Uses
HPLC columns are used for separating compounds that are not easily vaporized. These include polar, non-volatile, ionic, and thermally unstable substances.
Common Applications:
- Pharmaceutical Testing: API quantification, related substance analysis, dissolution testing
- Biotechnology and Life Sciences: Peptide, protein, DNA/RNA separations
- Food & Beverage: Sugars, vitamins, artificial sweeteners, preservatives
- Clinical Diagnostics: Bioanalytical testing of blood, urine, and plasma
- Herbal and Nutraceuticals: Polyphenols, flavonoids, alkaloids
- Chemical & Polymer Industry: Reaction monitoring, additive analysis
