Capillary column for the analysis of petroleum products Agilent J&W HP-PONA

The Agilent J&W HP-PONA capillary column is specially configured for detailed high-resolution analysis of refined petroleum products, including paraffins, isoparaffins, aromatic compounds, naphthenes and olefins. This stationary phase consists of 100 percent dimethylpolysiloxane, which provides the low polarity required for the separation of complex hydrocarbon mixtures. The key advantage of the speaker is its exceptional resolution. During the manufacturing process, each column is tested for compliance with strict industry quality standards, including mandatory confirmation of the separation of meta-xylene and para-xylene, as well as cyclopentane and 2,3-dimethylbutane. This test mixture simulates the most difficult-to-separate hydrocarbon vapors found in real petroleum products. The stationary phase is crosslinked and bonded, which allows the column to be rinsed with organic solvents to remove non-volatile residues without damaging the phase. This approach significantly extends the service life of the column when analyzing complex oil matrices. Each column is accompanied by a certificate containing the results of individual testing in terms of flushing parameters, sensitivity and effectiveness. The standard column geometry includes a length of 50 meters, an inner diameter of 0.20 millimeters and a film thickness of 0.50 micrometers. The operating temperature range ranges from minus 60 to 325 or 350 degrees Celsius. The speaker is available in three frame versions: 5-inch, 7-inch and for Intuvo 9000 systems. The column is fully compatible with the approved ASTM D5134 and ASTM D5441 methods.
