Zebron™ ZB-5ms GC Columns

The world is changing and we need to widen our Environmental Scope. Although analytical techniques and established regulated methods are not easily changed; more complex targets, larger lists, and a variety of sample matrices create a daily challenge for environmental chemists. By using the latest technologies and techniques in HPLC/ UHPLC and Sample Preparation, laboratories and chemists are able to develop better approaches to make their work Faster, Cheaper and Easier. Phenomenex is committed to supporting the industry through a comprehensive product portfolio of Sample Preparation, HPLC/UHPLC, and LC-MS, columns and accessories, along with application and method development services to meet industry needs.

This guide provides an overview of the three ways to choose your 5 phase column: by reviewing the column characteristics, choosing by applications & utilizing Phenomenex's online GC column finder. Find out more in this free download.

This helpful GC Selection Guide, from Phenomenex, provides a step-by-step process or choosing the best column to suit your needs. Including background on the master resolution equation, and choosing the best selectivity and dimensions for your experiment.

This white paper provides troubleshooting support for gas chromatography (GC). GC is a common technique used in analytical chemistry, which is used for separating and analyzing compounds that can be vaporized without decomposition. This guide will explain how to deal with common issues such as bleed, drift, and noise through a series of systematic steps, which will lead to improved results and prevention of re-occurrence.

In gas chromatography the Method Detection Limit, or MDL, is the minimum concentration of a substance that can be measured with 99% confidence that the analyte concentration is greater than zero. It can be difficult for GC analysts to find a method sensitive enough to meet the MDLs, this technical note from Phenomenex addresses that issue by discussing two methods which produce a sharper peak shape and have higher sensitivity.

This application note provides a comprehensive guide to the ZB-5MSplus™ GC column. To reduce potential surface activity, Zebron™ ZB-5MSPLUS™ is designed with a rigorous fused silica deactivation process that improves inertness and peak shapes for troublesome compounds. The ZB-5MSplus™ allows ultra-sensitive detection and accurate analysis of a variety of compounds such as cannabinoids in food and melamine in pet food.

This white paper provides a comprehensive guide to selecting the most appropriate GC column for your pharmaceutical methods. Careful selection is important to ensure that you produce the most accurate results and Phenomenex Zebron GC columns come in a variety of phase types to suit whatever pharmaceutical application that you are testing.

Often used for weed control, triazine herbicides have been found to have detrimental environmental and health effects. This application note presents two methods for triazine herbicide analysis. The method parameters follow the Environmental Protection Agency’s Method 536 for drinking water and Method 619 for wastewater, using LC/MS/MS and GC/MS respectively.

This application note describes the effective extraction of polycyclic aromatic hydrocarbon compounds (PAHs) from water samples while humic acids, which often interfere with chromatographic separation, are removed from the sample using a SPE sorbent, Strata® PAH. It was also found that Strata PAH provides consistent, high recoveries of all 16 analytes listed under EPA Method 550.1.

In this application note the Phenomenex roQ™ EN 15662 Method Extraction and dSPE QuEChERS Kits were used to successfully extract 25 pesticides of different classes from lettuce. Analysis was performed by LC/MS/MS using a Luna® C18(2)HPLC column and GC/MS using a Zebron™ ZB-5MSi column. This method produced acceptable recoveries and reproducibilities per the official EN 15662 method. The roQ QuEChERS dSPE MgSO4/PSA Kit can also be used for other fruit and vegetable matrices that are not highly pigmented.
