• (1) Agilent 7890B Gas Chromatograph System
• (1) Agilent 7693A Autosampler

Agilent 7200 Accurate-Mass Q-TOF GC/MS (G3851A) The 7200 Q-TOF incorporates a hexapole collision cell blanketed with nitrogen gas, to improve the ion fragmentation prior to detection quantification. It also includes new ion optics for focusing the ions prior to the flight tube and detector. This configuration has advantages for many applications. The data is interpreted through the use of the MassHunter WorkStation software, which provides quantitative and qualitative analyses of the data obtained. The 7200 Q-TOF can operate in either TOF mode or MS/MS mode. When operating in TOF mode, the instrument can obtain high resolution, accurate mass measurements, and fast full spectrum acquisition. MS/MS mode provides high resolution, accurate mass measurements, and fast full product ion spectra with high sensitivity. These features make the 7200 Q-TOF a good tool for solving complex analytical problems, resolving structural elucidation of unknowns, and confirmation of nontarget compounds. Features:

• Three turbomolecular vacuum pumps
• Rotary vane foreline pump
• Independently MS-heated removable EI or CI ion source
• Removable ion source (RIS), which allows quick change from EI to CI source with minimal loss of vacuum in the instrument
• Independently MS-heated hyperbolic quadrupole mass filter, which can be heated to high temperatures, minimizing the contamination typical with low temperature analyses
• Single hexapole collision cell
• Vacuum-insulated flight tube with dual-stage ion mirror
• Fast electronics, allowing fast sampling rates
• Analog-to-digital detector
• Independently GC-heated GC/MS interface with automatic retraction during source removal

Agilent 7890B Gas Chromatograph System The 7890B Gas Chromatograph (GC) System is the world’s most widely used GC system, featuring accurate temperature controls, precise injection systems, and high performance Electronic Pneumatic Control (EPC) modules for good retention time and area count repeatability. Features:

• Retention Time Locking (RTL) maintains exact retention times from injection to injection, column to column, instrument to instrument, and lab to lab
• Capillary Flow Technology (CFT) provides unique instrument capabilities, such as multi-dimension gas chromatography (GC-GC/Deans Switch), comprehensive two-dimension gas chromatography (GCxGC) with flow modulation, and backflush at the beginning, middle, or end of the analytical column
• Single filament TCD that does not require a separate reference gas, does not require manual potentiometer adjustment, and provides a stable baseline with a minimal amount of signal drift
• Auto-ranging FID provides the ability to detect and quantitate from parts per billion (ppb) to parts per thousand in a single injection
• Integrated SCD/NCD (sulfur or nitrogen chemiluminescence detector) provides low ppb detection, equi-molar response, and quantitation for sulfur or nitrogen contaminants without quenching from matrix
• Carrier Gas Options: Helium Conservation Module, Hydrogen Sensors and Alternate Carrier Gas Solutions dramatically reduce the amount of helium used to offer flexibility in your laboratory
• Large Valve Oven (LVO) allows for the combination of multiple methods and simplified maintenance
• Multimode inlet (MMI) serves as a programmable temperature vaporizing injector with flexible capabilities
• Agilent Inert Flow Path provides increased sensitivity for active compounds, from injection to detection
• Low Thermal Mass (LTM) modules, up to 4 installed and operating, increase sample throughput with rapid column heating and cooling

Agilent 7693A Autosampler The Agilent 7693A ALS (Automatic Liquid Sampler) provides reliable, fast, and precise injections for Agilent GC and GC/MS systems. The modular design allows this autosampler to grow with your lab. Features:

• 150 sample vial tray allows longer unattended operation
• Dual simultaneous injection saves time by doubling sample throughput
• Fast injection technology minimizes needle discrimination and enables use of external standards
• Sandwich injections of three layers eliminate manual error from internal standard, surrogate, or protectant additions
• Sample heater and mixer dramatically improves high molecular weight chromatographic results
• Heat the entire tray or cool it to sub-ambient temperatures to meet your lab’s needs
• Modular design allows the flexibility to easily move the sampler from GC to GC or start with a single injector and upgrade as needed
• Priority sample capability. There is no need to stop the sequence to add next most important sample
• Barcode reader allows the system to perform specific actions on mismatch, ensuring chain of custody Agilent Barcode Printing Solution.
• Extend the useful life of the 6890N GC by upgrading aging autoinjectors to 7693A
