PLOT Column Selection
PLOT Column Phase Cross-Reference: Similar Selectivity
Stable Bonded GC PLOT Columns
•
Innovative bonding process minimizes particle release, reducing column blockage
and protecting instrument parts.
•
More consistent flow means stable retention times in Deans and related flow
switching techniques.
•
Outstanding peak symmetry improves impurity analysis for gases, solvents, and
hydrocarbons.
