Thin-layer chromatography
of lipids |
|
|
|
|
|
Achieving an optimal
separation of lipids by thin-layer chromatography is not always
an easy task. In addition to the obvious importance of the materials
used (origin of the solvents and silica gel plates), thin-layer
chromatographic separations often greatly depend on environmental
factors such as room temperature and humidity. You were warned! |
