This Agilent 7697A Headspace Sampler comes fully refurbished by Conquer Scientific.
The Agilent 7697A Headspace Sampler is a gas chromatography (GC) sampling device that employs an inert sample pathway to automatically transfer volatile compounds from a sample matrix to a GC or GC/MS system. Built on the foundation of the 7890 GC and 7693A automatic liquid sampler, it is engineered to surpass the requirements of high-demand laboratories.
The automatic leak check verifies that each vial is free from leaks before analysis, maintaining precision and sensitivity. Hydrogen can be used as a safe alternative carrier gas. Priority sample positions allow for the inclusion of important samples that arrive late. Barometric pressure compensation ensures highly accurate and consistent results across various laboratories.
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
