Frequently Asked Questions
How do I choose the right GC column?
Start with the analytes, application method, stationary phase, internal diameter, length, film thickness, detector, and temperature program.
Which column is recommended for EPA 8260?
VOC and purgeable-organics methods commonly start with GsBP-624 or related VOC phases. Confirm dimensions and method requirements before ordering.
What is the difference between HP-5 and HP-5MS?
Both are non-polar 5% phenyl-style phase directions, while MS versions are commonly selected for low-bleed GC/MS workflows.
Can GS-Tek help find an equivalent column?
Yes. Use the cross-reference guide and submit the current part number, dimensions, method, analytes, and instrument model for technical review.
How long does a GC column typically last?
Lifetime depends on sample cleanliness, inlet maintenance, temperature exposure, carrier gas quality, and method conditions.
