The mid-range model holds up to 40 sample vials. The system thermostats up to 12 vials simultaneously for automated headspace analysis. A sophisticated nesting algorithm optimizes the 'virtual' oven size for maximum throughput.
Automated headspace sampler with built-in trap and standard PerkinElmer 9mL or 22mL sample vials. Up to 40 vials can be loaded into the removable vial magazine for automated analysis. Overlapping thermostatting of up to 12 vials in Constant Mode for maximum productivity. A patented optimization algorithm adjusts the virtual oven size for maximum throughput. An optional frequency-scanning shaker is available to reduce equilibration time. No optimization of the shaking process is required.
Headspace Gas Chromatography—for applications involving the solvent-free extraction of volatile compounds, it’s an unsurpassed technique, eliminating the time-consuming steps and risk of human error associated with other GC sample-preparation methods.
This paper will demonstrate the analysis of all three classes of residual solvents by pressure-balanced headspace sample introduction and GC-FID analysis. In addition to a discussion of the instrumental technique, the choice of the diluent will also be studied; two diluents will be used throughout.
This document is intended to provide the newcomer to headspace sampling with a concise summary of the theory and principles of this exciting technique. Enough information is included here for the user to understand the basic concepts and relationships in HS sampling to apply during method development and interpretation of data. Although emphasis is given to the PerkinElmer TurboMatrix™ HS systems, the document also covers alternative systems so that it should be useful to all potential users of HS systems.
Consumables reference guide for the TurboMatrix Headspace. TurboMatrix Headspace and high-sensitivity Headspace Trap samplers provide unparalleled precision and ease of use for numerous GC or GC/MS volatile-analysis applications. The system can manage up to 12 samples simultaneously, ensuring that the next sample is ready for analysis upon completion of the previous run, achieving significant time savings.
Food-packaging material is typically manufactured as a thin film and coated with inks which usually contain multiple, harmful, volatile organics.
