Biocompatible Columns
YMC provides two types of column hardware for bioseparations and coordination compounds. These columns suppress interactions between analytes and metals in the column inner surface and frits. The result is improved peak shape, high sensitivities, and excellent recoveries without the need for column preconditioning. Our biocompatible columns are also ideal for highly sensitive LC/MS analyses.
YMC-Accura products have received a thick application of bioinert coating on the inner column and frits. Our PEEK-lined columns have a double-layered structure that consists of a PEEK-lined inner surface with PEEK frits and a stainless steel outer tube.

YMC-Accura: Bioinert Coating
YMC-Accura hardware has been proven to deliver significantly higher sensitivity and recovery when compared to the same resin packed in a standard stainless steel column.
The durable bioinert coating remains on the column wall even after multiple packings.
PEEK-lined Columns
In the study below, the PEEK-lined column delivered improved peak shape and detected an additional peak that was not shown with the standard stainless steel column.
