Agilent G1888A Network Headspace Sampler CLEARANCE! As-Is

Agilent G1888A Network Headspace Sampler

The Agilent G1888 Headspace Sampler lets you automatically introduce volatile compounds from virtually any sample matrix directly into a GC or GC/MSD system. It features an inert sample pathway for superior chemical performance without analyte
degradation or loss. And its high sample capacity and increased sensitivity ensure excellent performance for a wide range of analysis.

Built-in performance and reliability

From sampling… to detection… to data analysis and reporting… Whether your application is pharmaceutical, food safety, environmental, or forensic… The G1888 is a fully integrated system that gives you unsurpassed confidence in your results.

Features:

• 70-sample tray and 12 positions in the heating oven allow unattended overnight operation for many applications
• Automated constant heating time is employed with optimized sample overlapping for maximum sample throughput in the minimum amount of time
• Deactivated sampling path, from sampling needle to transfer line, is standard so coupling with an inert 7890A or 6890N Volatiles Interface achieves complete chromatographic system inertness
• Controlled temperature range from 40 degrees C to 230 degrees C makes it possible to analyze semi-volatiles at temperatures over 200 degrees C, as well as traditional applications for low boiling point analytes
• Heated zones can be turned off, which allows analyses at ambient conditions for biological or extremely thermally sensitive analytes
• Incorporates two modes of multiple headspace extraction (MHE) in addition to routine single extraction (one sampling per vial)
• Multi-puncture extraction with up to 100 extractions per vial is possible for the analysis of samples in unusual matrices
• A 'concentration mode' of MHE allows multiple extractions from a vial to be made, followed by the start of the GC run after the last extraction
• Includes several convenient testing and troubleshooting features, including a set of four pre-stored chemical test methods, a semi-automated leak test, and a detailed power-on self-test
• Instrument control can be achieved using the GC ChemStation, MSD Productivity ChemStation and MSD Security ChemStation, or Cerity NDS for Pharmaceutical QA/QC
• Instrument control is integrated with drop-down menus for ease of method setup. The existing sequence table is used to set up analyses, maintaining optimized sample overlap and constant heating time.
• An event log function tracks every headspace sampler operation and reports any temperature and pressure deviation compared to the set point in compliance with 21 CFR Part 11
• Built-in keypad control enables compatibility with all GCs
