II. CONFIGURING AN ACQUITY UPLC SYSTEM FOR USE IN
SEC PROTEIN SEPARATIONS
a. Calibrators
In order to obtain the best performance from your SEC column, it is
important that your ACQUITY UPLC system is properly configured. It
is recommended that only pre-cut tubing is used, and that the ID of
all connecting tubing is 0.005” or less for optimal chromatographic
performance.
Size-exclusion chromatography may require modifications to an
existing ACQUITY UPLC system. Please refer to “Size-Exclusion and
Ion-Exchange Chromatography of Proteins using the ACQUITY UPLC
System” (P/N
715002147A ) for specific recommendations that can
be obtained at www.waters.com/chemcu
The sample loop used may affect the performance of your separation.
Optimally, select the smallest volume sample loop that is required
for the application. Sample loops larger than 20 µL with the ACQUITY
UPLC BEH SEC column are not recommended.
III. GETTING STARTED
A Performance Test Chromatogram and a Certification of Analysis
(COA) are available for each shipped ACQUITY UPLC BEH SEC column.
The COA is specific to each batch of packing material and includes the
batch number and chromatographic separation obtained using defined
protein standards. This document is available upon request at
www.waters.com/chemcu

a. eCord Installation
The eCord button should be attached to the side of the ACQUITY UPLC
column heater module. The eCord button is magnetized and does not
require specific orientation.
