I. INTRODUCTION
Thank you for choosing a Waters ACQUITY UPLC
column, and/or standard mix that are integral parts of Waters
ACQUITY UPLC SEC System Solution. The BEH125 SEC offering is
best suited for the analysis of peptides and proteins in the molecular
weight range from 1,000–80,000 Daltons that include insulin and
its aggregates. The BEH200 SEC column was designed to characterize
proteins ranging in molecular weight range from 10,000–450,000
Daltons that include monoclonal IgG monomers from aggregates,
while our BEH450 SEC is best suited for the analyses of proteins
and conjugates that range from 100,000–1.5 million Daltons
(Fig 1). All of these SEC chemistries are based on Waters Ethylene
Bridged Hybrid (BEH)-based particle technology and diol-bonded
surface that provide a stable chemistry with minimal non-desired
secondary interactions for proteins and peptides. The columns are
manufactured in a cGMP, ISO 9001 certified plant using ultra
pure reagents. Each batch of Protein Separation Technology SEC
packing material has been tested and qualified using a protein
test mixture (that is also available for purchase), and the results
are held to narrow specification ranges to ensure reproducible
performance. Every column is also individually tested for efficiency.
A Performance Test Chromatogram along with a Certification of
Analysis are available with each column.

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.

b. Column Connectors
It is is recommended to use the 150 mm column stabilizer
(P/N 205000365) to connect the ACQUITY UPLC BEH SEC column
to the ACQUITY UPLC system. A reusable fitting is supplied with the
ACQUITY UPLC column stabilizer.
c. Column Installation
1. Prior to placing the column on the system, purge the solvent
delivery system of any organic or water-immiscible mobile phases.
When connecting the column, orient it in the proper direction as
noted by the arrow on the column inlet side which indicates the
correct direction of solvent flow.
2. Flush column with 100% aqueous buffer, by pumping at a flow
rate of 0.2 mL/min.
3. Ensure that the mobile phase is flowing freely from the column
outlet. Attach the column outlet to the detector using .004” ID
tubing (P/N 430001562). Monitor the system pressure to
ensure the column is within its pressure limitations.
e. Useful Functional Tests for Benchmarking a New Column
Waters recommends performing a benchmarking test upon receipt of
your column and throughout the lifetime usage. By using a separation
of common proteins with an appropriate method, you can:
Verify the performance of the column upon receipt.
Monitor the condition of the columns for extended use.
Troubleshoot separation difficulties that may arise.
The BEH125 SEC Protein Standard Mix (P/N 186006519), BEH200
SEC Protein Standard Mix (P/N 186006518), and BEH 450 SEC
Protein Standard Mix (P/N 1860 06 842) were specifically designed
for this purpose with carefully chosen proteins and/or peptides
to provide a good representation of the intended application.
Figure 3 is an example of the Performance Test Chromatogram using
Part Number 18600 6519, Figure 4 is an example of the Performance
Test Chromatogram using Part Number 186006518. Figure 5 is an
example of the Performance Test Chromatogram using Part Number
186006842. These are typical results obtained in a waters laboratory
using 4.6 x 150 mm columns on an ACQUITY UPLC system.
4. Gradually increase the flow rate, by not more than 0.1mL/min at a
time, as described in Step 2.
5. Once the system pressure has stabilized, ensure that there are no
leaks at either the column inlet or outlet.
d. Column Equilibration
ACQUITY UPLC BEH SEC columns are shipped in 20% methanol
in water. It is important to ensure mobile-phase compatibility before
changing to a different mobile-phase system. Equilibrate the column
with a minimum of 10 column volumes of the buffer to be used
(refer to Table 1 for column volumes).
Table 1. Empty Column Volumes in mL (multiply by 10 for flush
solvent volume)
Column Dimension Approximate Volume
4.6 x 150 mm 2.5 mL
4.6 x 300 mm 5.0 mL
Buffer Preparation for Standard:
Chemicals:
- Sodium Phosphate Monobasic, Monohydrate
- Sodium Phosphate Dibasic, Anhydrous
- Milli-Q Water
Preparation of 100mM Sodium Phosphate Buffer (500 mL)
- Weigh out 500 ± 0.02 grams of H2O into a 500 mL beaker.
- Weigh out 3.55 ± 0.02 grams of Sodium Phosphate dibasic and
add to the 500 mL beaker.
- Weigh out 3.45 ± 0.02 grams of Sodium Phosphate monobasic
and add to the 500 mL beaker.
- Stir for a minimum of 30 minutes then filter the solution
through a 0.2 µm Millipore GV filter.
- Take the pH and record the value for reference purposes
(approximate pH: 6.8).
