Standard GC Analyzers: Configured for Performance and Productivity

Bruker configures and tests its standard GC analyzers to more than meet industry standard performance requirements for a variety of widely used methods (ASTM, UOP, EN, ISO, GPA).
Available in an array of configurations, Bruker Standard GC Analyzers utilise the leading analytical performance characteristics of the Bruker 400 Series of Gas Chromatographs to enhance productivity and ensure confidence in your results.

The method of choice for specifying the composition of spark-ignition engine fuels and its pre-cursors has predominantly been O-PIONA group type reporting (Oxygenates, Paraffin, Iso-paraffin, Olefins, Naphthenes and Aromatics) conducted using either single column or multi-dimensional gas chromatography. Due to the complex nature of high olefin samples and the additions of oxygenates, multi-dimensional gas chromatography is the most qualified technique as set out in ASTM D6839 – 02 ‘Standard Test Method for Hydrocarbon Types, Oxygenated Compounds and Benzene in spark-ignition engine fuels by gas chromatography’.

The independent trap temperature control design, trap capacity and trap selectivity allows the Bruker PIONA+™ Analyzer to optimise the analysis performance. In case of broad samples ranging from C4 up to C12, a high selectivity demand is required to separate the different groups. By using smart concurrent heating of both molecular sieves, the eluting profile of the paraffins (normal and iso) and naphthenes is well defined without the overlap of especially light normal paraffins in the iso-paraffin and naphthenes elution area. This reduces analysis time, improving analyses interpretation and quantitation, increasing sample throughput efficiency.

Bruker’s PIONA+™ Analyzer has the ultimate flexibility to include only those columns in an analysis to tailor the separation per sample stream type, including FCC naphtha, reformate, alkylate and gasoline. This is made possible by selecting the required mode of operation; (i.e. PIONA, PONA, PNA and oxygenated fuel additives, O-PIONA, O-PONA). PIONA+ Analyzer has the flexibility to undertake all these modes of operation, in a single instrument.
