- A 70-sample tray and 12 positions in the heating oven allowing 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
- A deactivated sampling path, from sampling needle to transfer line, is standard. When coupled with an inert 7890A or 6890N volatiles interface complete chromatographic system inertness is achieved.
- A controlled temperature range from 40 deg C to 230 deg C makes it possible to analyze semi-volatiles at temperatures over 200 deg 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
- In addition to routine single extraction (one sampling per vial), two modes of multiple headspace extraction (MHE) are incorporated in the G1888
- 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
- The sampler includes some convenient testing and troubleshooting features, inlcuding a set of four pre-stored chemical test methods, a semi-automated leak test, and a detailed power-on self-test
- Complete control of the G1888 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
- The G1888 can be controlled using its built-in key pad, which makes it compatible with all GCs
