BGB GC Columns and Capillary GC Specifications
Use the searchable table below to compare commonly requested GC column categories by phase polarity, dimensions and application. Exact BGB or supplied-manufacturer part numbers depend on the selected stationary phase, length, internal diameter and film thickness. Where a an exact catalogue number is available from Akira after the full configuration is shared, the table clearly states that contact Akira for the exact product configuration.

How to select the correct GC specification
GC column selection should account for phase polarity, analyte volatility, maximum operating temperature, column dimensions, film thickness, sample loading and detector type. A part number cannot be selected reliably from phase name alone because each dimensional combination normally carries a different catalogue number.
Request BGB GC Part Number AssistanceTechnical GC selection support
For dependable GC selection, compare stationary-phase chemistry, polarity, temperature range, dimensions, film thickness, sample capacity and detector compatibility. Use the BGB column selection guide and equivalent-column support before requesting a part number supplied by Akira.
Frequently Asked Questions
Technical answers for common BGB column selection, compatibility and quotation questions.
How do I choose the correct BGB GC stationary phase?
Match the stationary-phase polarity and selectivity to the analyte class, then reach Akira for temperature limits, column length, internal diameter and film thickness. Existing method details and the current column part number are especially useful for equivalency checks.
What is the effect of GC column internal diameter?
Smaller internal diameters generally improve efficiency and sensitivity but reduce sample capacity and require tighter flow control. Wider-bore columns provide greater sample capacity and are often easier to use for routine methods.
How does film thickness affect GC separation?
Thicker films increase retention and sample capacity for volatile compounds, while thinner films reduce retention and can support higher-temperature or faster separations. The best choice depends on volatility, concentration and method requirements.
Can BGB GC columns be used with GC-MS?
Many capillary GC phases are suitable for GC-MS when the selected phase has appropriate bleed characteristics and temperature limits. Suitability should be requested from Akira for the exact phase and dimensions.
Can Akira help identify an equivalent GC column?
Yes. Share the current manufacturer, phase, dimensions, film thickness, temperature range, application and part number. Akira can request a technically suitable BGB or supplied-manufacturer option for technical assistance from Akira.
How can I obtain the exact GC part number for every row?
GC part numbers normally change with phase, length, internal diameter and film thickness. A precise catalogue number should therefore be provided by Akira after the complete configuration is known.
When should a retention gap or guard column be used?
A retention gap or guard section can help protect the analytical column from non-volatile contamination, improve solvent focusing and simplify maintenance in demanding sample matrices.
What information is needed for a BGB GC quotation?
Provide the stationary phase, column length, internal diameter, film thickness, quantity, current part number, instrument type and application. This allows accurate part-number and availability technical assistance from Akira.
