@Analysis of Oxygenates & Aromatics

The system Analyzer contains one channel to determine oxygenates and a backflush to detector. In the same system using a different method the aromatics in gasoline or naphtha samples can be determined. An Automatic Liquid Sampler is used to inject a liquid sample.

The oxygenates in the sample are separated using a micropacked column and capillary column. The Aromatics in the sample are backflushed using the specified ASTM Method.

The aromatics in the sample are separated using a micropacked column and capillary column. The heavy aromatics in the sample are backflushed using the specified ASTM Method.

@Applications & Benefits

1. Method
