This Agilent 7890B GC with 5977A MSD, 7697A Headspace and Autosampler comes fully refurbished by Conquer Scientific.
The Agilent 7890B stands as a pinnacle in gas chromatography (GC), delivering unparalleled performance across all GC applications through advanced electronic pneumatic control (EPC) modules and precise temperature regulation within its high-performance GC oven.
The Agilent 5977 Series MSD serves as an independent capillary GC detector designed for compatibility with Agilent gas chromatographs.
The Agilent 7697A Headspace Sampler is a gas chromatography (GC) sampling instrument utilizing an inert sample pathway to efficiently transfer volatile compounds from a sample matrix to a GC or GC/MS system. Leveraging the technology of the 7890 GC and 7693A automatic liquid sampler, it is meticulously crafted to exceed the demands of rigorous laboratory settings.
Agilent 7890B 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-dimensional 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
- Helium conservation module and alternative carrier gas solutions dramatically reduce the amount of helium used to offer flexibility and cost savings for your laboratory.
Agilent 5977 MSD Features:
- Local control panel (LCP) for locally monitoring and operating the MSD
- One of two different high vacuum pumps
- One of three different foreline pumps
- Four different types of independently MSD heated electron-ionization (EI)
sources available: standard (stainless), inert, extraction (XTR), and high
efficiency (HES) - Optional chemical ionization (PCI/NCI) modes are available that add a
chemical-ionization (CI) source, reagent gas flow controller and plumbing,
and CI tuning calibration - Independently MSD-heated hyperbolic quadrupole mass filter
- High-energy dynode (HED) electron multiplier detector
- Independently GC-heated GC/MSD interface
Agilent 7697A Features:
- The 7697A Headspace Sampler 12-vial capacity configuration is perfect for academic labs and those with small sample loads
- Standard 111 sample configuration with three priority samples
- Trays can be exchanged during a sequence for increased sample capacity
- Hydrogen carrier and auto sleep/wake modes conserve valuable laboratory resources
- Independent control of vial pressurization and column head pressure provides increased precision by ensuring no back pressure during sample transfer
- Automatic vial leak test checks each vial during pressurization – without time-consuming calibration – to ensure that every sample is properly capped
- Sample bar code reader with data transfer capabilities allows you to track samples before they enter the oven
- Multiple headspace concentrations (MHC) with up to 100 extractions per GC start allows for more complete sampling and increased sensitivity
- Multiple headspace extractions (MHE) with up to 100 extractions per vial
- Supports 10-mL, 20-mL, or 22-mL vials without an adapter
- Samples depressurize before returning to the tray
- Transfer line interface accessory allows a headspace sampler and ALS to connect to the same inlet on the GC
