Accurate results.
Headspace chromatography
It's a user friendly instrument and repeatability is excellent.
Review Date: 9 Mar 2020 | Agilent Technologies
Excellent reproducibility, thanks the capacity we can measure the samples over the weekends.
Identification and control of residual solvents
Agilent 7697A Headspace Sampler has got great capacity of 111 samples by three 36 vial racks plus three priority positions. Headspace sampler can equilibrate (heat and shake) 12 samples simultaneously. It reduces significantly the time of analysis. The simple robotic arm, which transports headspace vials into the oven and back makes mistakes (headspace vial can fall out) very rarely: the probability is less than 1 ‰. It is for us acceptable. You have to reckon, that this headspace sampler should be connected to the gas chromatograph from the right side. The headspace sampler has got excellent reproducibility. I recommend this product.

The Agilent 7697A Headspace Sampler is based on the architecture of the 7890 GC and 7693A Automatic Liquid Sampler line of products. Automatic Leak Check ensures each vial is leak-free prior to analysis, with no loss of precision or sensitivity. Hydrogen can be safely used as an alternative carrier gas. Late-arriving important samples can be accommodated with Priority Sample Positions feature. Barometric pressure compensation automatically adjusts for changes in atmospheric pressure resulting in greater precision and consistent results across multiple labs.
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
- Control through Agilent OpenLAB CDS software and Agilent MassHunter software
- Other software control with Waters Empower™ 2 and Waters Empower™ 3 software
- 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
- Method development software transfers methods from any headspace system or quickly designs a method from scratch using just a few known parameters
- Samples depressurize before returning to the tray
