¡¡New GC Columns(1)

AbelBonded (AB) GC columns are developed and made in USA by ex-column tech gurus from brand name company with proprietary manufacturing process. AB columns not only replicate the performances of the brand name products, but also have improved the long-time known problems of the brand name ones. AB GC columns are offered at competitive prices to brand name products. With these features, AB GC columns are really best values products and gainful replacements of brand name products.

¡¡  Replicating performances

Column performances are characterized as stationary phase, column selectivity and retention time. AB GC columns are reengineered and made by the same stationary phases as that used by the brand name products. With stringent process control AB GC columns replicate column selectivity and retention times of brand name products for seamless column switching. Table I to II illustrate the performance comparisons of the most popular stationary phases: AB-5MS and AB-Inowax vs the brand name ones.

Fig 1 and 2 also graphically show such close performance comparison for these two popular stationary phase columns. Fig 1 is the graphic comparison of AB-5MS to Brand H-5MS, and Fig 2 is the comparison of AB-Inowax to brand H-Innowax.
 
Based on these comparisons, it can conclude that AB GC columns have essentially identical performances to the brand name ones.
