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 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.
PoraBOND Q is the long-term solution for analyzing volatile solvents and hydrocarbons. It is the most stable column of its kind and withstands repeated later injections. Due to our manufacturing techniques, the porous polymer is very pure and has virtually no catalytic activity.
Agilent J&W CP-Sil 5 CB is a high efficiency column containing a 100% dimethylpolysiloxane phase. Separation is almost entirely based on boiling points, making this column suitable for a wide range of applications with a broad temperature range.
Agilent J&W HP-88 is designed for the separation of fatty acid methyl esters (FAMEs). It provides greater cis/trans resolution than the DB-23, and has nearly identical selectivity as the CP-Sil 88, but with higher temperature limits.
Agilent J&W Ultra 1 is a 100% dimethylpolysiloxane, nonpolar column that resembles HP-1 but with tighter specifications for retention index and capacity factors. Agilent J&W Ultra 2 is a (5%-phenyl)-methylpolysiloxane, nonpolar column and resembles HP-5 but with tighter specifications for retention index and capacity factors.
Agilent J&W DB-35 columns are ideal for conformational analysis. The DB-35 is a (35%-phenyl)-methylpolysiloxane, mid-polarity column with low bleed.
