The high capacity model holds up to 110 sample vials, making it ideal for maximum productivity and throughput. The instrument calculates the optimum thermostatting time for up to 12 vials, achieving the highest throughput possible.
Concurrent desorption of the next sample while the current sample is undergoing GC analysis optimizes productivity. Also incorporates loading of internal standard into clean tubes to provide sample-integrity validation and to improve precision (repeatability) of the analysis. Allows the ability to condition tubes during chromatography to minimize downtime and enhance productivity and also includes separate trap clean and test function, which saves time and protects the GC column and detector.
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 application note will focus on automated headspace sample introduction without the use of an internal standard. It will follow the EN 14110 method and then show a modification to simplify and speed up the analysis. Compared to the analysis of free and total glycerin in B100 biodiesel, the analysis of residual methanol is very easy.
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.
