AC Reformulyzer® M4

Fast group type analysis of gasoline and gasoline blend streams using multi-dimensional gas chromatography


In today’s dynamic market, accurate and fast analysis of product composition can be a source of key competitive advantage for refiners and petrochemical plants. Hydrocarbon group type composition of naphtha’s and gasolines is a key parameter for product quality and process control. Labs around the world use many different methods, often referred to as PIONA analysis, to determine the group type composition. This is an extremely challenging task, due to the enormous variety and complexity of sample types.

AC Reformulyzer is the only technology available that will provide accurate and reliable group type composition.

By using a proprietary, multi-dimensional separation approach which is unrivalled in the industry, coupled with simple and robust detection technology, highly accurate results are obtained regardless of sample matrix. Easy-to-use, dedicated Reformulyzer software helps analysts and operators start analysis with just a few clicks and generate reliable data 24/7.


Increase Revenue with increased daily sample capacity

The Reformulyzer M4’s short analysis time allows to run up to 100% more samples per day* and it enables labs to comply to the significant in-tank and in-ship blending time constraints related to key-point analysis.

Reduce Operational Cost with Robust Design and Advanced Technology

The Reformulyzer M4’s advanced technology significantly reduces maintenance and system down-time. In combination with the improved sample capacity the total operational cost per sample is reduced by 50%.*
