For users that require on-site purification of samples, MacCHESS offers an AKTA Purifier system at the beamline. Basic UV and pH detectors are available and samples may be fractionated directly into the sample 96-well plates used by the BioSAXS robot. We currently recommend that users bring their own columns, but MacCHESS does provide a Superdex 200 10/300 column from GE for general use. We do plan to purchase a variety of columns in the future.
