Laboratory Columns

GPC Columns provide environmental sample clean-up.

PL EnviroPrep GPC Columns permit one-stage clean-up procedure, according to EPA Methods, for determination of pesticides in variety of matrices such as soil and animal tissue. Matrix is extracted and higher molecular weight fractions such as lipids, polymers, natural resins, and dispersed high molecular weight components are eliminated. Featuring 10 Â-µm particle size and...

High Resolution Columns are designed for organic GPC.

PlusPore series columns, designed for high resolution organic gel permeation chromatography (GPC), are made using polymerization process to produce particles which exhibit specific, controlled pore structure. Multi-pore structures have pore volume compared to PS/DVB packing materials and offer chemical and physical stability. They permit transfer across full range of organic solvents with little...

Drawdown Columns check flow rate of metering pumps.
Laboratory Columns

Drawdown Columns check flow rate of metering pumps.

Calibration Columns measure drawdown rate on suction side while leaving discharge undisturbed in normal steady state operation condition. Products can also be used to determine if check valves are worn or dirty. Available in capacities from 100-4,000 ml, products are suited for use with pump capacities up to 120 gph. Constructed of PVC, units have slip-on top caps for filling and cleaning....

Distillation 101: A Guide to Distillation and Separation Technologies

Distillation is a separation unit operation that involves multiple countercurrent-stage steps, separating two or more volatile components. This results in the contact of liquid and vapor most generally in counterflow. Distillation 101: A Guide to Distillation and Separation Technologies provides an in-depth look at everything you need to know about distillation, including: Design procedures Equipment components Applications

Column separates peptides and proteins.

Model PLRP-S 3 Â-µm column comes in 100Ã… and 300Ã… pore sizes. Media is offered packed in short columns for rapid resolution LC/MS, where complete chromatographic resolution is not required, as MS is used to provide detailed information. Longer columns in 2.1 and 1.0 mm ID are available for higher resolution separations. PLRP-S 100Ã…...

Capillary Columns have high temperature limits.
Laboratory Columns

Capillary Columns have high temperature limits.

ValcoBond® Capillary Columns receive individual rigorous testing to insure they meet standards for resolution, retention characteristics, inertness, bleed, and reproducibility. High upper temperature limits enhance column bake out, reducing sample carry-over and cycle times. Liquid phase processing produces low bleed characteristics while maintaining identical retention characteristics.
