Restek– GC column portfolio
Analytical GC capillary columns
A wide selection of conventional fused-silica capillary columns for general and targeted analytical applications.
Typical phases and types:
- non-polar and low-polarity columns
- medium- and high-polarity phases
- general-purpose columns for routine analyses
Applications:
- VOC, SVOC
- solvents
- hydrocarbons
- volatile organic compounds
Specialised GC columns for target analytes
For applications where selectivity is critical and standard columns do not provide adequate separation.
Typical analyte groups:
- nitrosamines
- pesticides
- PAHs, phthalates
- sulfur- and nitrogen-containing compounds
- explosives, active pharmaceutical ingredients
GC columns for environmental and food analysis
Columns developed specifically for standardised methods.
Typical applications:
- drinking-water and soil analysis
- food safety
- mineral-oil fractions
- biodiesel, FAME
- MCPD, MOSH/MOAH
Chiral GC columns
Columns optimised for separating the enantiomers of optically active compounds.
Applications:
- pharmaceutical chiral analysis
- flavours and fragrances
- biologically active components
- GC PLOT and packed columns
- For analysing gaseous or highly volatile components
Typical applications:
- light hydrocarbons
- permanent gases
- residual solvents
