Summary

We present a modified circuit for the “PNA-analyser”, which allows analysis for paraffins, naphthenes and aromatics in the under 200°C fraction of a sample having a final boiling point above 200°C. The modified separation scheme gives, in addition, improved type separation. By the introduction of adapted instrumentation the analyser has been suited to fully automated serial analysis. The new concept will eventually be commercialized.
