The sample size is determined by three factors: the size of the difference between the means that should be detected, the precision of the methods being compared and the significance levels at which the test is performed.

The established kinetic plots clearly show that monolithic columns are suited for large plate number separations whereas in the small plate number range the 3 ?m packed bed system is to be preferred.

Although there are other possible causes, the most common source of fronting peaks is a disturbance in the column packing bed. The fix is straightforward: replace the column.

A good pretreatment system combines reverse osmosis and electrodeionization technologies.

The trend towards dedicated analytical solutions continues to gain momentum while what might have been considered high performance instrumentation a few years ago are increasingly being viewed as routine techniques.

The instrument is "a splendid example of automatic analysis."

Thermo Electron Corporation has recently been presented with two Omega NorthFace ScoreBoard awards for excellence in customer service.
