11 We guarantee column performance and quality thru 100% column testing with industrial stringent test samples for: K value: stationary phase film thickness for reproducibility RI: stationary phase to ensure brand equivalence Plate number: film thickness uniformity lead to good separations Peak height ratio: column inertness for accurate quantitation Bleed : phase thermal stability to prolong column life time Length and ID, to commit our specification and interchangeability To ensure equivalence performance of GsBP columns to other major brand columns
