Ratio of Deproteinization (PK-2A)

The ratio of deproteinization with MSpak PK series ( Columns for Column switching ) and with a corresponding column of other company were compared. Since the ratio of deproteinazation is high, PK-2A can suppress the adsorption of protein to analytical columns or LC/MS as much as possible, and keep the reproducibility of analysis.
