This Application Note describes a rapid method for analysis of polynuclear aromatic hydrocarbons (PAHs) in soil and sediment samples by GC-MS using an Agilent Low Thermal Mass (LTM) GC/MS system and Capillary Flow Technology QuickSwap for Backflush. The cycle time for GC-MS analysis of PAHs was dramatically improved through the combined use of a narrow-bore (180-µm id) column installed in an LTM module and capillary column back-flushing with QuickSwap. Improvements were achieved while maintaining resolution. Agilent Capillary Flow Technology enabled column backflushing to remove low-volatili- ty material from the capillary column, reducing bakeout and maintenance time. The method resulted in increased sample throughput and lab productivity, while maintain- ing analytical performance.

This application note describes a method for the analysis of volatile organic compounds (VOCs) in water using static headspace-GC/MS, including method optimization, sample preparation, and analytical method.

This application note is targeted for ultra-high productivity of total petroleum hydro- carbons (TPH) analysis in environmental laboratories. Agilent's Low Thermal Mass (LTM) technology is employed here to perform ultra-fast gas chromatographic (GC) separations. The LTM technology uses a column module combining a fused silica cap- illary column with heating and temperature-sensing components wound around it, which can be heated and cooled very efficiently. In this application note, the speed of analysis for the hydrocarbon group eluting between C10 and C44 can be dramatically increased to about 13 times faster than a conventional method. In addition, the ultra- fast cooling function of an LTM module can reduce the total GC cycle time to 5.1 minutes. The simultaneous dual-tower injection from Agilent is used to further double productivity. The final result for TPH analysis productivity is 5.1 minutes per two samples.

This application note describes the application of EPA Method 1694 for screening and confirming the presence of 65 pharmaceuticals in water samples using the Agilent G6410A Triple Quadrupole mass spectrometer (QQQ).

This application demonstrates the trace-level analysis of polybrominated diphenyl ethers (PBDE) using electron impact single quadrupole scanning mass spectrometry. Agilent Technologies Inc. has implemented new testing procedures to evaluate the column inertness performance more effectively. The study focuses on the importance of PBDE analysis in understanding food supply and environmental quality worldwide.

This document describes the features and characteristics of the OPA241 series and OPA251 series single-supply, micropower operational amplifiers from Burr-Brown Corporation. These amplifiers are designed for battery-powered portable applications and feature low power consumption, single-supply operation, rail-to-rail output swing, wide supply range, low offset voltage, high common-mode rejection, and high open-loop gain.

The OPA237 op amp family is one of Burr-Brown's MicroAmplifier series of miniature products. In addition to small size, these devices feature low offset voltage, low quiescent current, low bias current, and a wide supply range. Single, dual, and quad versions have identical specifications for maximum design flexibility. They are ideal for single supply, battery operated, and space-limited applications, such as PCMCIA cards and other portable instruments.
