Anybody worked with this resin can share his experience?
What about column packing? Mobile phase system? Sample application?
Which fractions are important? Wash of the resin? The sample to resin percentage?
Can anyone who used Sephadex LH-20 in separation or purification of compounds share his experience? How many times can I change the mobile phase in the experiment? And what about using organic...
