With excellent resolution for PAH isomers, it allows for the rapid, easy, and accurate quantification of PAHs in environmental and food samples. Since all isomers are separated in a single run, reliable analysis results without false positives can be obtained. 【Features】 ■ Completely separates all PAH isomers, providing accurate analysis results without false positives ■ Fully separates EPA-designated PAHs, including chrysene, triphenylene, and benzo(a)fluoranthene, in under 7 minutes, and EU-regulated PAHs in under 30 minutes ■ Provides rapid results in a single analysis ■ High sensitivity due to low bleed *For more details, please refer to the PDF document or feel free to contact us.

Column "CP-Select 624 CB"

Column "CP-Select 624 CB"

Excellent column-to-column reproducibility! Highly reliable qualitative/quantitative results can be obtained.

The "CP-Select 624 CB" is a column that further enhances the reproducibility of the proven 624 stationary phase. Bleed is kept to 1/2 to 1/3 of that of typical columns (for a column with a length of 30m, an inner diameter of 0.53mm, and a film thickness of 3.00μm, the bleed specification is 9pA). With 6% cyanopropylphenyl and 94% dimethylpolysiloxane as the stationary phase, maximum inter-column reproducibility is ensured through rigorous synthesis based on strict standards and thorough characterization. 【Features】 ■ Reliable and precise separation of EPA-designated volatile compounds according to EPA methods 524.2, 624, and 8015. ■ Designated column for the pharmacopoeial method V.3.3.9 for residual solvent analysis, ensuring compliance. ■ Excellent inter-column reproducibility. ■ Low bleed. *For more details, please refer to the PDF document or feel free to contact us.
