Lab training is designed for works whose result would be few tens of milligrams (ca 50 mg) of pure compound which is a sufficient amount for chemical characterization. The intention is to learn to work with small amounts and with special equipment and labware as is usual for research work isolating compounds of natural origin.
Aim of the course -
Last update: TAJ342 (30.09.2013)

Students will be able to:

Isolate and purify small amounts of compounds from natural materials

Work with labware designed for semi-micro preparative scale

Design procedures and equipment suitable for work with small amounts of compounds

Perform spectral and other characterization from small amounts of isolated compounds
