This system includes:. - Shimadzu GCMS-QP2010. - Shimadzu GC 2010. - Shimadzu AutoSampler AOC-20s. - Shimadzu AutoInjector AOC-20i. Automated sample introduction is a critical aspect of any gas chromatography system. The AutoInjector must be capable of injecting samples into a variety of injection ports including split/splitless, direct (WBI), cold on column (OCI), or programmed temperature vaporization (PTV). The injection parameters must also be controlled to optimize sample analysis. The new AOC-20 (Automatic Operation Controller) handles all of this and more, providing the ideal solution to your lab's challenges. The AOC-20 stands for highest reliability, which means that the device provides reproducible results and causes minimal problems such as bent needles, evaporating samples, etc. To maintain reproducible results, regular maintenance is required, such as changing the injection port septum or syringe. With the AOC-20, these procedures are easy and you can perform them conveniently without fear of negatively affecting the device's performance. The challenge in today's laboratories is to process large numbers of samples and different types of bottles automatically. Additionally, increasingly lower detection limits require increased flexibility for various injection techniques, including large volume injection (LVI), solvent flushing, and solvent flushing with a second solvent. The AOC-20 overcomes these challenges and increases throughput to meet your productivity goals. Auto Sampler AOC-20s:. The flexible handling of up to 150 vials significantly increases laboratory productivity. The AOC-20s AutoSampler's carousel and robotic arm allows sample transport to the AOC-20i AutoInjector with 1.5 mL and 4.0 mL vials. The system is also intelligent. It can tell the difference between vial types by reading the information from the vial tray in use. The AOC-20i/AOC-20s is a powerful automation tool for the GC laboratory that allows the user to exploit the full capabilities of the GC system. This refurbished Shimadzu GCMS-QP2010 with GC 2010 and Shimadzu AOC-20s AutoSampler is in good condition. We have specific expertise in the field of analytical devices. Labprocure is responsible for this device.
