Gas Chromatography-Mass Spectrometry

The GC/MS system operated in the Centre is a Varian 4000 Performance, that permits internal and external ionisation and also the possibility of chemical ionisation. Ionisation, by chemical means or by electron impact, may be switched during the analysis, creating various segments. This system also permits analysis GC/MSn (n < 5). Pure compounds and solid samples may be analysed by using a “chromatoprobe”.

More information relating to preliminary studies of samples or further details regarding the characterisation process, may be requested from Professor Pier Parpot. The exact cost of analysis and the probable date of completion will be indicated after the conditions of characterisation are established. All samples must be accompanied by an <analysis request form> downloaded from this page.
