It is important as a separation technique in intra-site chronological analysis and inter-site comparisons.

It is a powerful separation technique using a discontinuous electrical field to create sharp boundaries between the sample constituents.

The third type of separation is still experimental; practical separation techniques all depend in some way on the atomic mass.

This property sets it apart from other separation techniques.

Some scientists believe that currently available purification and separation techniques are adequate, or nearly so, to isolate the human stem cells too.

There are other separation techniques, but they involve principles other than size recognition.

This differs from other separation techniques which depend upon chemical or physical interactions to separate analytes.

Without some rather sophisticated separation techniques, this cannot be done.

This separation technique can be useful in mining iron as it is attracted to a magnet.

Furthermore, the low abundance and difficult separation techniques necessary make it a scarce commodity.
