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). Important Loading contaminated samples onto the column may disrupt solvent flow ...
Performance comparison between Aurora Series columns and competitors
The data in the bar graph below was achieved under the following conditions: Competitor 1 column: 50cm X 75μm Commercial solution without integrated tip Competitor 2 column: 50cm X 75μm Commercial solution with integrated emitter tip IonOpticks ...
Low amounts (1mM - 10mM) of HEPES in a sample
The presence of small concentrations of HEPES should not affect the column chemistry, however, there is a significant risk of fouling the emitter tip leading to spray instability as HEPES is not volatile and may deposit on the tip.
Removal from a UHPLC
Where possible, we recommend not to remove the column from a UHPLC system before performance falls and the column requires replacement. However, removal may sometimes be required for instrument servicing or maintenance. For more information on ...
