The Reformulyzer M4 AC from Analytical Controls by PAC is the only analyzer that combines the analysis of paraffins, olefins, naphthenes, oxygenates, and aromatics in a single instrument and, if desired, in a single gas chromatographic method.
The analyzer guarantees:
-
Excellent performance and faster analysis times - 39 minutes compared to the previous 75 minutes (M3 revision)
- Ease of use and flexibility of use
- Full method compliance: EN ISO 22854, ASTM D6839, ASTM D5443, IP566, SH/T 0741, GB/T 28768-2012 test methods.
The Reformulyzer M4 is built on the Agilent 8890 GC platform. The GC's integrated intelligent features increase system productivity and help reduce analysis costs. Advanced technology significantly reduces maintenance and system downtime, which, combined with improved sampling capacity, reduces total operating cost per sample by 50%.
The analyzer ensures the quality of the data obtained thanks to:
-
Certified quality control samples and Diagnostic Tool® for validation and performance evaluation
- Unique AC PMP User Group Meeting for exclusive interlaboratory QC loops with results sharing.
The Reformulyzer M4 analyzer introduces significant improvements over the previous M3 model:
-
Reduction in analysis time to 39 minutes from the previous 75 minutes (M3 revision). Faster analysis times enable refineries to make quicker decisions and take action to ensure products are within specifications; to analytical laboratories to double productivity
- New, more robust olefin trap with longer life (up to 75% olefins) and new design for all traps.
- Easier access and replacement of capillary columns only
IRIS® Reformulyzer software: includes pre-programmed methods and analysis modes
- New switching valves, no needle valves
- Carrier gases: Nitrogen and Hydrogen. The use of N2 reduces costs and eliminates the risks of helium approval.
- The M4 Reformulyzer guarantees the quality of the data obtained thanks to: Certified quality control samples and Diagnostic Tool® for validation and performance evaluation

Instrumental and application updates:
-
The pre-fractionator option extends analysis capacity. The pre-fractionator allows analysis of the PIONA composition of the light end (up to C12) in hydrocarbon products with a maximum final boiling point of 525˚C / 977˚F. The heavy fraction is not analyzed; it is separated from the lighter fraction of the sample and discarded in a dedicated vent. Contaminated or out-of-spec products can be analyzed without the risk of fouling the analyzer, and information on the hydrocarbon groups present (up to C12) in the contaminated product is obtained, as well as a quantitative result for the light fraction itself.
-
Prefac option, a dual inlet for sample injection. A PTV (Temperature Programmable Vaporizer) injector that includes the pre-fractionator, combined with the Reformulyzer's Split/Splitless (S/SL) injector. Heavy samples with a FBP up to 525°C are injected into the PTV injector only in Prefrac mode. Boiling point separation of product on pre-column (in inlet). Up to C11 analyzed on Reformulyzer M4 system, heavy part back-flushed to vent. (see Application Note: Reformulyzer M4 with sample pre-fractionation option).
- Gasoline analysis in accordance with revised ASTM D6839-21 and ISO 22854. The Reformulyzer is one of the most widely used analyzers, with over 500 instruments installed worldwide, for determining the total aromatics, total olefins, benzene, oxygen, and oxygenates in finished gasoline. Many international fuel specifications refer to Reformulyzer-compliant methods in accordance with ISO 22854 or the recently revised ASTM D6839 (see Application Note: Gasoline analysis in revised ASTM D6839-21 and ISO 22854).
- Analysis of gasoline containing various oxygenates. Recently introduced, the OXY gasoline operating mode is intended as an additional method alongside the standard mode dedicated to a more traditional mixture containing only one or two oxygenates. The OXY gasoline mode (55 minutes) should be used if you need to analyze more complex oxygenate mixtures in a finished gasoline. The “Gasoline OXY” mode is an extended version of the standard “Gasoline” mode, optimized for separating more complex oxygenate mixtures.
