4. Usable Conditions
*1 When analyzing under 40 °C, set the flow rate at less than 0.5 mL/min to reduce the column load.
*2 Increased temperature slows down the formation of sugar anomers, and thus prevents peak splitting.
Usable solvents are listed below.
(1) The standard eluent is water.
(2) Up to 20 % (v/v) acetonitrile or ethanol is usable.
Caution! · The eluate may contain lead counter ion attached to the sulfo group. In particular, presence
of acids, bases, or inorganic salt ions in the eluent or sample makes it easier for lead ion
to desorb. Please be careful when disposing the eluate.
Attention! · Use the column within above stated flow rate, pressure, and temperature ranges. Using
the column outside the given range may damage the column and lower its performance.
·Column pressure is influenced by the eluent composition, flow rate, and column
temperature. When changing the eluent compositions, adjust the flow rate and column
temperature so that the column pressure remains below the usable maximum pressure.
5. Eluent Preparation
(1) Degas the eluent fully to prevent the formation of air bubbles.
(2) Presence of small debris or insoluble substances may result in deterioration of the column and/or they appear
as noise on the chromatograms. Filter the eluent with a 0.45-μm disposable filter to prevent the problems.
Attention! · Whenever water is required, use ultra-pure water freshly generated by a water purification
system or water from a newly opened HPLC grade distilled water bottle. Use HPLC grade
organic solvent whenever possible. Solvents left in an opened bottle for a long time should
not be used. The content may have been changed, absorbed moisture, or has been
contaminated.
· Always use freshly prepared solvents. Solvents stored for a long time may have changed
their compositions and may influence elution patterns and/or damage the column.
Note · Use of on-line degasser is recommended.
6. Sample Preparation
(1) If possible, use the eluent for analysis to dissolve or dilute samples. If this is difficult, use a solvent which
has a composition that is as close as possible to the eluent's composition, but which fully dissolves or dilutes
the sample. When gradient elution is used, it is recommended to use the initial eluent to prepare the sample.
(2) Filter the sample solution using disposable 0.45-μm filter to prevent the column from clogging or deteriorating.
(3) Recommended sample injection volume is less than 10 μL per column.
(4) When analyzing an acidic or a basic sample, make sure to neutralize the sample prior to the injection.
(5) When a sample contains cations other than lead ions (the pretreated sample after neutralization), remove
them by using a cation exchange resin.
(6) When a sample contains protein or lipid, make sure to remove them prior to the injection. Proteins may be
removed by ultrafiltration or by adding acid or acetonitrile. If using acid to remove the protein, neutralize the
sample before injection. If using acetonitrile, make sure that the final acetonitrile concentration is less than
20 % (v/v).
(7) When a sample contains a large amount of organic acids, use an OH-form anion exchange resin to remove
them.
(8) When a sample contains hydrophobic substances or surfactants, use a reversed-phase solid phase
extraction to remove them.
Note · Use of guard column is recommended to protect the analytical column.

7. Column Usage Procedure
7.1 HPLC System Preparation
Wash entire LC system prior to the column installation, including all flow-lines and sample loop by switching the
valve, and then replace the washing solution with the eluent to be used. If desired new eluent has low
miscibility/solubility to the eluent of previous analysis, first use the eluent that is miscible/soluble to both eluents,
and then replace it with the desired eluent.
e.g. When replacing chloroform to water, first run methanol and then introduce water.
Attention! · If the eluent left in the system is not compatible with the column to be used, it may damage
the column.
· A drastic change in the eluent compositions may remove substances adsorbed on the
system and they may enter and deteriorate the column.
7.2 Column Installation
(1) Connect the column to LC system by following the “flow direction arrow” (➡) indicated on the column name
tag.
(2) Make sure to insert the tubing all the way to the end fitting and secure it with the male nut. It is important that
there is no extra space between the tubing and the column side of the end fitting. Presence of an extra space
will let the sample to spread out and may result in wide peaks.
(3) Set the initial flow rate at 0.2 - 0.3 mL/min and start the system. If using the column at an elevated
temperature, keep a low flow rate until the temperature of the column reaches to the set temperature, and
then gradually increase the flow rate to the desired.
(4) At the end of analysis, reduce the flow rate to 0.2 - 0.3 mL/min and turn the column oven off. Make sure that
the column oven temperature is at room temperature before turning off the pump.
Caution! · Verify that there is no solvent leak. It may cause electronic leakage, rust, and/or chemical
injury.
Attention! · Make sure not to let air bubbles enter the column while installing the column. The air
bubbles may damage the column.
· When restarting the system after column installation or after holding the eluent flow, start
the system at 0.2 - 0.3 mL/min. A rapid increase in pressure can damage the column.
· If the column was used at an elevated temperature, let the column temperature return to
room temperature before stopping the pump. If the pump was stopped while the eluent
inside the column was still hot, as the eluent temperature decreases, its volume also
decreases. This may result in creating an empty space in the column and deteriorates the
column.
Note · It is recommended to set the pump limiter to avoid exceeding the maximum pressure.
7.3 Solvent Exchange
When replacing the solvent, set the column temperature at 70 - 95 °C and start the system at 0.2 - 0.3 mL/min.
Recommended solvent volume to introduce at each step is 3 to 5 times of the column volume.
Attention! · Frequent eluent replacement may damage the column, and thus not recommended.

7.4 Column Cleaning (Regeneration)
Problems in peak shapes and elution time changes or elevated column pressure etc. are often caused by
insoluble or adsorbing components present in the eluent and reagents being deposited inside the column. These
problems may be resolved by cleaning and/or regenerating the column. When washing and/or regenerate the
column, let the washing solution flow from the column outlet go directly into the waste container and not let the
solution go through the detector.
<Cleaning Method>
Insoluble components that block the column inlet may be removed by reversing the flow direction, i.e.,
introducing the eluent from the column outlet, with flow rate at less than half of the recommended flow rate.
<Regeneration Method>
Presence of cations other than lead ion in the sample may replace the lead ion attached to the sulfo functional
group. This can change the separation patterns and peak shapes. Following regeneration procedure reattaches
the lead ions and may resume the column performance.
Set the column temperature between 70 - 95 °C and introduce water at 0.5 mL/min flow rate.
Inject 50 μL of 0.2-M aqueous lead nitrate solution several times.
Caution! · Please be careful when disposing the eluate containing lead nitrate solution.
8. Column Storage
Remove the column from the system after replacing the in-column solvent with the shipping solvent. Securely
tighten the end caps and store the column at a location with stable temperature (a cool and dark space is
recommended). Refer to section 7.3 Solvent Exchange for how to replace the eluent.
Attention! · Never allow inside of the column to dry. It can damage the column.
9. Column Inspection
