Finnigan MAT DELTA
Isotope Ratio Mass Spectrometer

With the Finnigan MAT DELTA we can perform gas isotope ratio measurements of

H/D, 13C/12C, 15N/14N, 18O/16O, 34S/32S

In this laboratory, we equip the basic instrument with a dual inlet system, a external system for purified gas samples collected by the Vacuum Extraction Lines and a gear system for up to 46 small samples about 0.2-0.3mg with automatic tube crackers. In the latter system, we drop phosphoric acid on the sample to get carbon dioxide and extract them before analyzing the gas.

The operation of the mass spectrometer is fully computerized and controlled by the Finnigan MAT software ISODAT operating in multitasking mode (realtime), i.e. different procedures such as

• instrument operation and control
  
• sample preparation
  
• data acquisition
  
• data processing for screen and printer output

are performed in parallel.
