Elemental analytical analysis

The Optimass 8000 is an inductively coupled plasma ionisation mass spectrometer (ICP-MS) employing a time-of-flight (ToF) mass analyser.

With the Optimas 8000 the analyte ions are orthogonally extracted from the primary ion beam for time-of-flight mass analysis. This provides ultra fast mass spectral measurements and results in greatly reduced interferences from neutral species. Implementation of orthogonal extraction with time-of-flight analysis avoids the necessity for complex ion optical systems to deal with such interferences, and hence provides an elegant technique to increase the sensitivity, speed and precision of element analysis.

The technique enjoys the ability to detect and quantify all elements in seconds. Method development is facilitated by the simplicity of obtaining a full mass spectrum in 1 s allowing the analyst to take a snapshot of the composition of the sample and then determine what elements need to be quantified and which do not. Elements in the ppq to ppm range can be determined with confidence.
