Usage

Guard Column System extends the life of valuable analytical columns by trapping contaminants from the sample and mobile phase, thereby preventing loss of retention. This system is ideal for use with proteins or other biopolymers that may be contaminated or absorbed by steel surfaces.

Selection of Guard Column
Use a guard column with identical packing materials to the analytical or preparative column. Regarding size, use the same or smaller inner diameter and short column length (10-50 mm). When the sample is sensitive to metal ions, it is more appropriate to choose PEEK material. For example, some protein analyses will use the PEEK guard column (analysis).
