  5. I had to 007 otherwise many (with the exception of yourself) would never have deduced the identity.:);)
  6. Here's one that the A2 Group did last week (Isoamyl Acetate). I could annotate it but this would spoil it for your students.:D

  7. As promised here are the traces for Butylamine and trimethylamine. Note the differences for the Primary and Tertiary (aliphatic) Amine.

  9. Just finished analysing the distillate our First Year BTEC did yesterday when they tried to obtain Limonene from Orange Peel. The sample , with a score of 0.93 (ou of 1.00) was the top match in the Instrument's Library.

  10. Just analysed the samples our Year 1 BTEC Applied Science students produced when attempting the synthesis of Ethyl Ethanoate. The results were excellent.:)
