Detailed Hydrocarbon Analysis
The purpose of detailed hydrocarbon analysis (DHA) is to determine the bulk hydrocarbon group type composition (PONA: Paraffins, Olefins, Naphthenes and Aromatics) of gasoline and other spark-ignition engine fuels that contain oxygenate blends (Methanol, ethanol, MTBE, ETBE, and TAME) according to ASTM-D6730. PONA analyte identification is conducted by matching retention indices with normal hydrocarbon paraffins. However, chromatograms obtained in PONA analyses have an extremely large number of peaks and their analytes may be mislabeled. Without accurate and reproducible retention indices, this may result in erroneous PONA ratios. The GC-2030 incorporates an Advanced Flow Controller that enables highly precise flow control, and makes it easy to analyze and identify detailed hydrocarbons. Shimadzu offers DHA analysis conforming to the following methods: ASTM-D5134, ASTM-D6729, ASTM-D6730, and ASTM-D6733.

Ethanol In Gasoline Analyzer
InfraCal 2 ATR-E
The InfraCal 2 Ethanol Blend Analyzer for measuring percent ethanol in gasoline is the ideal solution where a quick, accurate, on-site measurement is required and a single, repetitive ethanol blend analysis is needed. The InfraCal 2 ATR-E is based on proven IR technology, and used by fuel terminals, laboratories and regulatory agencies worldwide. The compact, easy-to-use InfraCal 2 ATR-E has a measurement range of 0-20 & 70-98%% ethanol in gasoline and an accuracy of +/- 0.2%. These results are comparable to ASTM D4815.
