NEW Liquid, Headspace & SPME Sampler for GC Systems
You don't need more than one autosampler to automate your GC. The all in one autosampler combines the functions of an autosampler for liquid, static headspace and SPME in a single unit. Because of its flexibility, it can easily be installed on all the GC and GC/MS systems available on the market, serving up to two injectors in most configurations. The rotating tower leaves the injector port free for inlet maintenance. This approach keeps the samples away from any heated source. In fact, the sample rack is mounted away from the GC oven to prevent exposure to high temperatures, which could cause degradation or condensation in the sample vial.
The all in one autosampler handles the most sophisticated sampling techniques, including the internal standard technique (also known as sandwich injection), multi-phase, priority injection, hot & cold needle, nano-litre injection and much more. Parameters are easily programmable to optimise both the most convenient sampling methods for both extremely volatile or viscous samples and the best injection technique. Variable needle depths allow samples to be taken from anywhere within the vial, thus performing an extractions directly from the vial. The all in one autosampler features a great solvent capacity and a wide solvent selection: it supports the use of six solvent vials of 10ml each, giving a total capacity of 60ml.
The robotic vial processing operation allows for sample analysis in a straight forward and systematic way. Sample vials are transported into the heated six-position incubator for preconditioning. The sample is simultaneously heated and shaken, in order to facilitate the state change and to reach equilibrium. A heated, gastight syringe is then moved over the incubator and the headspace sample is withdrawn. After sample injection, the syringe is automatically cleaned by purging with inert gas. The all in one autosampler syringe-only concept allows for sequential injections, even with samples characterized by highly dissimilar features. Even the most chemically active compounds can be analysed, without needing to change any of the sample pathways. Furthermore, it permits adjustable sample volumes without loop changes.
The all in one autosampler supports the derivatisation pre- and postextraction, as the required by the different SPME applications. The extraction is carried out in the heated and shaken oven: the possibility of setting the shaking speed to very low allows for the minimisation of mechanical stress on the fiber. The oven cover is kept closed during the extraction phase: this is very important to ensure temperature homogeneity, especially if the extraction time is very long. The unit supports the post-extraction fiber washing in the liquid phase by immersion in an opportune solution, as well as the post-desorption fiber cleaning by exposition in the injector or in an external cleaning station (optional).
