Advancing Environmental Methods »
Some of the most common environmental tests include phenols, polycyclic aromatic hydrocarbons (PAHs), and mixtures of bases/neutrals/acids (BNAs). These applications present challenges due to the broad range of their extended compound lists. As a result of their activity, many compounds in these samples exhibit poor peak response, asymmetrical peak shape, breakdown, frequent system maintenance and poor column lifetime. By not using products specifically designed for this type of analysis, laboratories risk large amounts of system downtime for maintenance and recalibration for these tests.

Meet EPA 8270D requirements with Zebron ZB-SemiVolatiles GC Column
An improved method for EPA Method 8270D providing benefits such as fast run times while maintaining resolution of key compounds and great peak shape of typically poor performing compounds.
Results shown are the analysis and purification of PAHs by Phenogel™ GPC columns and the removal of biomaterial matrix interferences that are known to complicate the analysis of PAHs in biological tissues.

A New Perspective in Pesticides Analysis »
As demands grow for more sensitive monitoring of pesticides, herbicides, and PCBs, analytical methods must improve to meet the low-level detection requirements. The active nature of these compounds often leads to chromatographic issues like poor response, breakdown, and tailing analytes. Phenomenex delivers specialized technologies to overcome these challenges while also improving resolution power, allowing for shorter run times and increased productivity.

Method development strategies for successful pesticide analysis.
This analysis can be performed by LC/MS/MS or GC/MS, providing resolution and sensitivity improvements as well as time savings.
Save time and costs by eliminating the need for additional columns and instrumentation traditionally required to achieve sufficient separation of all PBDE congeners.
Your laboratory’s analysis of VOCs in air, drinking water, wastewater, and solid waste helps ensure the public’s safety from harmful contaminants. As your partner in environmental analysis, Phenomenex offers dependable GC solutions that produce dependable results, so you can confidently stand behind your data and achieve your specific method goals.
There are two simple things that analysts can do in order to meet the method detection limits (MDLs) requirements. Learn how to improve your GC analysis in this technical note.
When analyzing via GC, two factors need to be taken into consideration, a compound’s boiling point and its ability to interact with the stationary phase.
Easy seals are designed for easy tightening
Explosive residues monitoring low level detection and extremely sensitive analytical methods. Found frequently through site remediation projects, explosive residues contain compounds like nitramines, nitroaromatics, and nitrate esters that pose serious health concerns. In the United States, liquid chromatography is used in EPA Methods 8330 (LC/UV) and 8330B (LC/MS) to analyze explosives, while gas chromatography is used in EPA Method 8095.

Critical Choices: Best Practices for Improving GC Methods »
Environmental contamination from oil leaks or spills may result from a variety of sources, including underground storage tanks (UST) and gasoline pumps. The analysis of fuel samples may be broken into 2 main fractions: Gasoline Range Organics (GROs) and Diesel Range Organics (DROs). While GRO compounds have boiling points similar to gasoline, DRO compounds have boiling points similar to diesel fuel (C 10 –C28 ), ranging from 170–430 °C.
