Exo isomer was eluted first closely followed by the endo isomer. Exo isomer exhibited tailing and sometimes continued to elute even after elution of the endo isomer was completed. Thus, the endo isomer was usually contaminated by the exo isomer. Usually, a repeated chromatography was needed to obtain a pure endo isomer. Scaled up experimental .

The group work is a valuable part of systematic training and alerts people to other training opportunities. Most have been on training courses provided by a range of early years support groups and charities and to workshops run by individual settings.
