Methods included are...
Determination of Volatile Organic Compounds in the Cabins of Vehicles by Agilent 8890 GC/5977B MSD and Thermal Desorption Sampler
HJ/T 400-2007 was used to determine the concentration of volatile organic compounds (VOCs) in the cabins of vehicles. This Application Note presents a method for their analysis using an Agilent 8890 GC/5977B MSD and a Markes’ TD 100-xr automated thermal desorption (TD) system.
Analysis of USP <467> Residual Solvents of Class 1, Class 2, and Class 3 using the Agilent 8890 GC/ FID /5977B MSD System
This application note demonstrates excellent peak shape, resolution and great repeatability, which shows this FID and MSD dual-channel system is a powerful tool for qualitative and quantitative analysis of residual solvents.
EPA 8270E with Pulsed Split Injection and Retention Time Locking on an 8890 GC with a 5977 Series MSD
This application note demonstrates system optimization, calibration, and method performance for the recently revised EPA 8270E on an Agilent 8890 GC system coupled with an Agilent 5977 Series single quadrupole mass spectrometer.
Determination of Ultratrace Polychlorinated Dibenzo-p-dioxins & Dibenzofurans
This study developed a gas chromatography triple quadrupole mass spectrometry (GC/MS/MS) method for the analysis of seventeen 2,3,7,8-substituted PCDD/F congeners.
Determination of 14 Polycyclic Aromatic Hydrocarbon Compounds in Edible Oil
This application note presents the development and validation of a multiresidue method for the analysis of heavy polycyclic aromatic hydrocarbon (PAH) (more than four rings) residues in five edible oils.
Quantitation of Pesticides in Strawberries at Tolerance Levels Established by the US EPA
To test the suitability for the determination of pesticides in strawberries at the tolerances established by the US EPA, which vary between 10 and 25,000 ppb, the Agilent 8890 gas chromatograph was coupled to Agilent 7000D and 7010B triple quadrupole mass spectrometers.
Contaminants Screening Using High-Resolution GC/Q-TOF and Expanded Accurate-Mass Library of Pesticides and Environmental Pollutants
The software described in this application note, simplifies the review of such data whilst maximizing its value, to allow labs to quantitate priority targets and reliably screen for many more suspects, all achieved simultaneously in one environment.
Short Chain Chlorinated Paraffins (SCCP) Analysis Using Negative Chemical Ionization (CI) and Low Energy EI by High-Resolution 7250 GC/Q-TOF
The Agilent 7250 Series high-resolution accurate mass GC/Q-TOF was used to analyse one of the most challenging group of compounds, short chain chlorinated paraffins (SCCPs), using a comprehensive approach including both negative chemical ionization (NCI) as well as low energy electron ionization (LE-EI).
EU Priority PAH Analysis in Pumpkin Seed Oil Using Bond Elut EMR–Lipid Cleanup by GC/MS/MS
European Union priority polycyclic aromatic hydrocarbons (PAHs) were analysed in pumpkin seed oil using a liquid-liquid extraction, followed by Bond Elut EMR—Lipid (EMR—Lipid) and PSA/C18/MgSO4 dSPE (PSA/C18/MgSO4) cleanup. PAHs were quantified using a gas chromatography triple quadrupole mass spectrometer (GC/MS/MS) equipped with an Agilent JetClean self-cleaning ion source and backflush.
