Separations is a fundamental scientific discipline focused on the isolation and purification of components from mixtures. Through techniques such as chromatography, distillation, and filtration, separations scientists separate substances based on their physical or chemical properties. This field plays a crucial role in various industries, including pharmaceuticals, food and beverage testing, environmental science, materials research, and more. Explore how separations techniques enable precise analysis, quality control, and the development of innovative products.
Agilent J&W DB-EUPAH columns are designed and tested to provide the most optimal performance for all 16 EU-regulated polycyclic aromatic hydrocarbons (PAHs). The columns are individually tested with an application-specific QC test probe mixture and deliver excellent resolution of critical PAH isomers, such as benzo(b,j,k)fluoranthene.
Agilent J&W CP-Sil PAH CB UltiMetal combines the advantages of a highly thermo-stable stationary phase with UltiMetal stainless steel as the column material. This unique column separates all 16 PAHs according to EPA method 610.
Agilent J&W HP-PAS5 nonpolar columns are specifically designed and processed for the analysis of organochlorine pesticides. With an operating temperature range of -60 to 325/350 ºC, all HP-PAS5 columns are ECD-tested to assure minimal pesticide breakdown and low ECD bleed.
Agilent J&W DB-608 columns are precision-engineered to deliver industry-leading performance in the effective analysis of chlorinated pesticides and PCBs. DB-608 widely used for U.S. EPA methods 608, 508, and 8080, and deliver excellent inertness and recoveries, without resulting in pesticide breakdown.
Agilent J&W VF-5 Pesticides columns are specially designed for the determination of trace levels of pesticide residue. Every column is individually tested before shipment with key pesticides, including endrin and aldrin, ensuring optimal performance and consistency of results.
Agilent J&W CP-Sil 8 CB for Pesticides delivers a linear column response down to femtogram levels. The column is supplied with an intergrated retention gap to avoid problems with solvent condensation, thus allowing repeated splitless injections without phase deterioration.
Agilent J&W Select Low Sulfur meets the specific needs of petrochemical chemists who need lower detection limits for sulfur components in propylene. This column provides significantly lower detection limits due to the highest inertness towards volatile reactive sulfur components.
Agilent J&W CP-SimDist UltiMetal performs extended analysis to C120, and is guaranteed to a Tmax of 450 °C, due to the virtually unbreakable inert UltiMetal tubing. The internal diameter of UltiMetal tubing is the same as for fused silica 0.53 mm id (Megabore) columns, providing trouble-free automation of on-column injection.
Agilent J&W CP-Wax 51 for Amines is designed for the analysis of C4-C10 amines, diamines and aromatic amines. The column conforms to EPA method 607.
Agilent J&W DB-Petro is a 100% dimethylpolysiloxane phase, precision-engineered for the analysis of PONA, PIANO and PNA from petroleum processes. These high resolution DB-Petro columns are bonded, cross-linked, and solvent rinsable, and have been extensively QC tested to the strictest industry standards.
