- Promix is for separation of biomolecules
- Promix is an alternative chromatography technology for efficient resolution of peptides and proteins.
- The technology is based on a combination of two interactions – hydrophobic and ionic.
- This approach is possible due to a new type of separation media: a chemical combination of hydrophobic and ionic functional groups on a ligand bonded to a silica support.
- With this phase, unparalleled selectivity and peak capacity can be achieved.
- Independent adjustment of the amount of buffer and organic modifier creates an infinite number of separation conditions that are suitable for many types of biomolecules.

There are four different Promix Columns to be selected as follows:
Use the following chart to select a column based on the analyte’s properties
Select the column length based on sample complexity
- 150-250 mm for proteomics, protein digests, and complex samples
- 50-150 mm for synthetic analysis and purification
Select the column i.d. based on sample loading and sensitivity needs
Mobile Phase should be pH 2-4 with:
Formic Acid (0.1-0.9%)
Ammonium Acetate or Ammonium Formate
Organic Modifier should be Acetonitrile
Ionic strength, pH, and organic modifier gradients can be used to optimize the separation
