Agilent_sVOCS_in_drinking_watersAnalysis of Semivolatile Organic Compounds in Drinking Water on the Agilent 8890 GC and 5977 GC/MSD with Extended Calibration Range
This application note coupled an Agilent 8890 GC with an Agilent 5977 MSD to analyze semivolatile organic compounds in drinking water sources according to United States Environmental Protection Agency (EPA) method 525. This workflow generated results that met method 525 calibration criteria, and demonstrated that this system is sufficiently sensitive to detect most of the low-level standards analyzed.



Agilent_sVOCS_Sintered_Frit_LinerAnalysis of Semivolatile Organic Compounds with Agilent Sintered Frit Liner by Gas Chromatography/Mass Spectrometry
Gas chromatography/mass spectrometry (GC/MS) is integral to the analysis of semivolatile organic compounds in environmental matrices. Depending on the complexity of the matrix, where some environmental matrices such as soil or wastewater matrices contain many nonvolatile compounds, the selection of the liner is crucial to longer lifetime of the GC/MS system and less downtime. This application note shows how the Agilent sintered frit liner offers extended lifetime of the GC/MS system before performing inlet maintenance, as well as excellent reproducibility.

Agilent_increased_thermal_stabilityIncreased Thermal Stability and Maximum Temperature of the Agilent J&W DB-HeavyWAX Column
One-hundred percent polyethylene glycol columns, also known as WAX columns, are used for a wide variety of applications, such as industrial chemicals, flavors, and fragrances. Traditional WAX columns have a maximum temperature limit of 250/260 °C due to issues such as decreased thermal stability, which reduces the potential range of applications. This application note describes how the Agilent J&W
DB-HeavyWAX, with its extended temperature limit of up to 280/290 °C and increased thermal stability, can increase injection-to-injection reproducibility.


Agilent_reduced_carryoverReduced Carryover and Improved Reproducibility in Pyrolysis Gasoline ASTM D6563 Analysis
This application note evaluates the performance of the Agilent J&W
DB-HeavyWAX column for the analysis of pyrolysis gasoline. This analysis is challenging due to the presence of higher molecular weight aromatic compounds, which can cause carryover or extended analysis times. The J&W DB-HeavyWAX, with a maximum temperature of 280 °C isothermal and 290 °C programmed, can operate at higher temperatures than traditional WAX-type columns, allowing faster and more reproducible analysis of pyrolysis gasoline.
