7697A Headspace Sampler
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. Barometric pressure compensation results in highly precise and consistent results across multiple labs.

Product Details
- 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
- Transfer line interface accessory allows a headspace sampler and ALS to connect to the same inlet on the GC

Journal Article Describes FDA Test for Quality Assessment of Liquid Hand Sanitizers Using Agilent Headspace-GC/MS
This work describes the FDA’s Center for Drug Evaluation and Research (CDER) laboratories efforts to develop tests to assess the quality of hand sanitizer products containing ethanol or isopropanol as the primary active ingredient. The products were evaluated using an Agilent headspace-GC/MS for the active ingredient content and determination of the 12 impurities listed in the FDA Hand Sanitizer Temporary Guidance.

Scientists at Merck Develop New Headspace-GC Method for the Analysis of NDMA in Pharmaceutical Products
This article describe a sensitive, specific, accurate, and precise method for the analysis of N-nitrosodimethylamine (NDMA) in pharmaceutical products using full evaporation static headspace gas chromatography with nitrogen phosphorous detection. It has the potential to serve as a universal method for testing all semi-volatile nitrosamines across different drug products.
