Formulated to support synthetic operations, the Spe Polypropylene Column Chromabond ® Sioh-H 2 So 4 /Sa, 50 Unit(S) is designed for extraction of PCBs from oil, in accordance with the German industrial standard DIN 51527, part 1. This unique phase consists of a special combination of SiOH-H 2 SO 4 - a silica phase impregnated with sulfuric acid, and SA - a strongly acidic cation exchanger based on silica with benzenesulphonic acid modification. The open tubular syringe-shaped column with Luer tip outlet features a particle size of 45 µm, a pore size of 60 Å, and a specific surface area of 500 m²/g, ensuring efficient separation and enrichment. The recommended storage temperature is
