USED AGILENT TECHNOLOGIES 7890A / 5977A / 7697A / 7693

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
