Service spectrum

We support the following ionisation:

• Electrospray-ionisation (ESI)
• Electron-impact-ionisation (EI)
• Matrix assisted laser desorption ionisation (MALDI)
• Ionisation per field desorbtion (LIFDI)
• Direct chemical ionisation (DCI)
• Atmospheric pressure chemical ionisation (APCI)
• Desorption elektrospray-ionisation (DESI)

Application

• High resoluted mass spectrometry for exact masses
• MS/MS-experiments per elektrospray-ionisation and APCI via fragmentation of polar, highly volatile und thermic instable compounds
• Ion nmobilty MS
• GC-MS-investigation to mixtures of volatile compounds (by prior arrangement)
• HPLC-MS-investigation to mixtures of highly volatile compounds (by prior arrangement)

Measure orders only with the GöChem system please (see link "measure orders")!
