幸运8平台彩票 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.
Increasing demands for efficiency, productivity, data quality, and profitability pose ongoing challenges for lubricant testing labs, like yours. Whether you need to achieve quick turnaround times, minimize downtime, or maximize lab efficiencies, you can rely on PerkinElmer for a comprehensive set of simple-to-use and proven testing solutions to help you achieve accurate results in record time.

幸运8平台彩票PerkinElmer offers fast, robust, easy-to-use, and proven lubricant testing solutions. By leveraging our industry experience and partnering with global organizations like ExxonMobil and Caterpillar, we offer customers a unique level of understanding.
幸运8平台彩票Residual solvents are used in the manufacture of active pharmaceutical ingredients (APIs), excipients, or in preparation of drug products and are not removed during the purification processes. Residual solvents are one of the three main impurities in pharmaceutical materials.
Residual solvents do not provide any therapeutic benefit and should be removed to the extent possible, fulfilling quality based requirements as per International Conference on Harmonization (ICH) guidelines – this is one of the standards to control the quality and the purity of the pharmaceutical substances, excipients, or drug products.
This paper will demonstrate the analysis of all three classes of residual solvents by pressure-balanced headspace sample introduction and GC-FID analysis.
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.
幸运8平台彩票The Polymer Market consists of a huge diversity of manufacturers of industrial products running many different processes yet still facing similar challenges. There is more and more pressure to achieve high product quality and reduce costs in order to stay one step ahead of the competition.
Food-packaging material is typically manufactured as a thin film and coated with inks which usually contain multiple, harmful, volatile organics.
