Organic SEC (GPC) Columns

Shodex organic SEC (GPC) columns have a history of more than twenty years and have been used numerous customers all over the world. The current series is of an improved type based on the long term experience and the latest technology.
Five types of GPC columns packed with different solvents are available to avoid solvent replacement. Moreover, custom columns packed with other solvents such as quinoline, o-dichlorobenzene, ethyl acetate, tetrachloroethane and dimethylacetamide are available uponyour request.

The following columns are availble as the standard column.

1) In-column solvents

THF KF-800, KF-600, KF-400HQ, LF series
Chloroform K-800 series
DMF KD-800 series
HFIP HFIP-800, HFIP-600 series
Toluene UT-800, HT-800, AT-806MS series

2) Types

Mixed gel columns Mixed gel type columns are packed with mixture of gels which are different in pore size are to have wide linear range in molecular weight calibration curves from oligomers to macromolecules.
The mixed gel columns have “M” at the end of the column name.
Linear type
columns (1)		 Linear type columns are specially designed to have wider linear range in molecular weight calibration curves than that of mixed gel columns. Linear type columns are highly recommended for correcting non-linear sections of molecular weight calibration curves of ordinary columns.
It is highly recommended that linear type columns than ordinary type columns or mixed gel columns be used when both of them are available.
The linear type columns have “L” at the end of the column name.
Linear type
columns (2)		 Linear type columns with special designed packing material.
Semi-micro GPC Columns Small volume type columns are of 4.6mm ID column. The internal volume of 4.6mm ID column is about one third of 8.0mm ID column.
Smaller particle size enables higher-resolution fractionation. Detection sensitivity is about four times higher than that of standard GPC columns. A single column can substitute for conventional analysis using two or more coupled columns, which shortens analysis time.
Downsized GPC Columns Small volume type columns are of 6.0mm ID column. The internal volume of 6.0mm ID column is about one third of 8.0mm ID column.
With small volume type column, by reducing the flow rate to one third, the same separation as with 8.0m ID columns can be obtained. And, the consumption of eluent will be also one third.
Small volume type columns are good for reducing the consumption of potentially-environmentally-damaging organic solvents.
High Temperature Columns The high temperature columns can be used for the GPC analysis at elevated temperature up to 230 °C.
Solvent-Peak Separation Column Solvent-peak separation columns delay the elution of low-molecular components and can be used to separate a solvent peak or other troublesome peak to realize accurate measurement of molecular weight distribution. The use of the columns with 805L, 806L, 806M and 807L columns is recommended.

Column Information

For SEC analysis, sample concentration is very important. The following is the pretreatment procedure of sample.

Basically, the sample should be dissolved in the same solvent that is to be used as the eluent.

1) Dissolving the sample in such solvent will make the blank peaks as small as possible.

2) In case the sample has a molecular weight of 1,000,000 minimum, soak it in such solvent for 12 to 24 hours to let it swell. After the swelling, stir the solvent gently for dissolution.
Strong agitation or use of an ultrasonic bath for dissolution will degrade such sample.

3) In case the sample is a polymer, its concentration in the solution and the injection volume should be 0.05 to 0.5% and 50 to 100micro-L, respectively.
If the concentration is higher, the retention volume of the sample will increase. The optimum concentration changes with the molecular weight and the viscosity. The following table gives the molecular weight vs. the optimum concentration.

Molecular weight Sample concentration
(W/V%)		 Injection volume per column
KF-600 series KF-800 series
< 5,000
less than 1.0
 micro-L to 100 micro-L
5,000 to 25,000
less than 0.5
25,000 to 200,000
less than 0.25
 30 micro-L
200,000 to 2,000,000
less than 0.1
> 2,000,000
less than 0.05

4) In case the sample is organic, it is desirable that the concentration be 1% maximum and the injection volume, 50micro-L maximum.

The GPC UT-800 columns have been developed to prevent shear degradation in the high molecular weight range. The existence of shear degradation can be confirmed using a multi angle laser light scattering(MALS) detector, which has high sensitivity in the high molecular weight range and can measure absolute molecular weight. This shows the comparison of results of analysis of high density polyethylene(HDPE) using conventional columns and UT-806M columns. Detection was performed using MALS and RI detectors. With conventional columns, the highest molecular weight portion detected was around 5,000,000. On the contrary, with UT-806M, the highest molecular weight portion was around 20,000,000 and the results show that high molecular weight portions which cannot be measured using conventional columns exist. Regarding weighted mean molecular weight values(Mw) obtained from GPC calibration curves, Mw using UT-806M columns is higher than tat using conventional columns. From the above results, it can be concluded that shear degradation in the high molecular weight range occurred with conventional columns, but, not with UT-806M columns.

Please refer to the following tables for the classification of solvents in terms of capability of being replaced with original in-column solvent. However, frequent replacement of in-column solvent may shorten column life, and is, therefore, not recommended. We can replace the in-column solvent with another solvent such as o-dichlorobenzene, ethyl acetate, dimethylacetamide or methylpyrrolidon upon your request.
