How to Properly Cut Capillary Columns
chips Clean cut cracked column delaminated polyimide glass fragments
Cleanly cut column ends are important in CE for minimizing electric field distortions, but in GC a bad cut can cause leaks or even catastrophic column failure.
Proper cutting technique eliminates glass fragment generation, minimizes the probability of cracks and provides a square cut that is free of chip and tangs with the circumference of polyimide intact.
