| Abstract:Objective:Comparison and identification of pyridoxal phosphate(including importation and own preparation).Meth- ods:TG/DTA scanning and analyse.Results:They were unanimous that characteristic thermal diagram of pyridoxal phosphate which importation and own reparation,this shows that own preparation was successful.At the same time difference that peaking temperature and the peaking area was due to their different purity.Conclusion:Differential thermal analysis method are simple and speedy for to i- dentification of materials. |
