Lasdy, the importance of electroceramic substrates and insulators should not be overlooked. Here one strives to raise the breakdown strength by eliminating the interesting conduction mechanisms just described. Spark plugs, high voltage insulators, and electronic substrates and packages are made from ceramics like alumina, mullite [55964-99-3] and porcelain [1332-58-7].

The developments in instrumentation include production of dedicated machines. For example, with the introduction of the Attomole 2000 , HVEE (High Voltage Engineering Europe B. V., P.O. Box 99,3800 AB Amersfoort, The Netherlands, Phone +31 33 4619741 Fax +31 33 4615291) has made available a compact C Isotope Ratio Mass Spectrometer ( C IRMS) for biomedical applications. The system provides C/ C ratios down to 10 from sub-milligram samples in typically a few minutes. Both solid samples (carbon) as well as CO, can be analyzed. The Attomole 2000 combines a compact instruments package with the extreme sensitivity of large tandem accelerators that are normally found in big research centres.
