Operation of Aurora Series Columns - Sample Preparation
Prior to loading samples onto your Aurora Series column, the sample should be de-salted and should not contain any contaminants (salts, detergents, solid particles, etc).
We recommend performing the following on your sample:
- SP3, FASP or S-trap assisted digestion
- De-salt with C18 Stage-tips
Loading contaminated samples onto the column may disrupt solvent flow or foul the emitter tip leading to a loss of performance.
Please submit a support ticket if you would like further details on recommended sample preparation protocols.
