Motions in nature, for example ocean waves, can play a significant role in tomorrow's electricity production, but the constructions require adaptations to its media. Engineers planning hydropower plants have always taken natural conditions, such as f

In exploratory scale biotechnological process development, the product must be rapidly identified although a reference compound may not always be available. LC-diode-array detection and MS were used for this purpose in a process producing 9alpha-hydr

Fused silica capillary columns containing α-chymotrypsin-modified silica were used to separate the enantiomers of naproxen. The separation was followed with a fluorescence detector that could be moved to several positions along the column. The inter

A new impurity has been found in some batches of metoprolol tartrate. As the amount exceeded 0.1% it was of interest to deduce the structure. Techniques involved in solving the problem were LC, LC-MS and GC-MS. The LC systems showed that the impurity
