Initial operation and buffer compositions
Once the column is connected to your UHPLC system and is placed inside the source heater or housing, begin operation using 70% buffer B at a flow rate equivalent to the desired gradient flow rate for around 10 minutes or until the pressure is stable ...
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). Important Loading contaminated samples onto the column may disrupt solvent flow ...
Peptides from a sample that are not captured during the loading step
The stationary phase used in our columns has a lower retentivity of peptides than other stationary phases (peptides are eluted at a lower %ACN than other stationary phases). Therefore, there is a small amount of peptides that will not bind to the ...
Column volumes and equilibration
Before each run, Aurora Series columns should be equilibrated with a minimum of 4 column volumes of 100% buffer A. Column volumes: Frontier 60x75, 60 cm X 75μm: 2.65μl Ultimate 25x150, 25 cm X 150μm: 4.42μl Ultimate 25x75, 25 cm X 75μm: 1.1μl Elite ...
Standby and idle conditions
To optimise column lifetime and performance, we recommend that the following conditions are met while your instrument is standby and idle mode: The instrument continues to run at the desired operating pressure The instrument ideally continues to run ...
