KEY FEATURES

EASY TO USE

For routine analyses, the HT2800T features one-touch operation. After loading the sample, you just need to enter a range of vial numbers and push the START button. The full-color touch screen interface provides easier system accessibility and usability. The touch screen eliminates drilldown, simplifying instrument control for both novices and experienced users. All system parameters and settings are graphically displayed for a quick and easy set-up, requiring minimal user training.

THE IDEAL CHOICE FOR YOUR GC

You don’t need more than one autosampler to automate your GC. The HT2800T combines the functions of an autosampler for liquid, static headspace and SPME in a single unit. Because of its flexibility, the HT2800T 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.

SWITCH BETWEEN MODALITIES

HT2800T allows for quick and easy switching from one application to another on the same GC workstation. Regardless if your samples are processed in headspace, liquid, or SPME mode, or if the method requires split, splitless or on-column injection, your new instrument set-up is ready in a few minutes. The quick switch means that there is no transfer line to disassemble, no bulky turret to store or move across the laboratory, no complex re-alignment procedures. It takes you less than 5 minutes to perform a few, quick, simple tasks: select new injection modality on the touch screen, change the syringe and load a new sample rack, if the application requires it. You are then ready to continue the analysis, without downtime.

PRODUCTIVITY

The samples can be run as fast as the GC will allow, because a sample is always ready to be injected when the previous run is completed. In fact, for maximum throughput, HT2800T is equipped with six-position oven that allows the optimization of preparation times for headspace and SPME applications.

SMART TECHNOLOGIES FOR THE BEST USER EXPERIENCE

HT2800T benefits from a unique portfolio of patented, proprietary or licensed technologies that have been put together by our R&D team to make your user experience amazing. To provide additional robustness to your headspace analysis, HT2800T features system integrity and vial leakage check functionalities. The system integrity test can be automatically performed with every batch of samples: going behind preventive maintenance counters, the test checks syringe and plunger integrity by a heuristic procedure to discover early system failure. Instead, the vial leakage check can be included to monitor the pressure inside vials of the same batch – again by a heuristic procedure – in order to check against anomalous values that are indicative of a vial leakage problem.

In addition, our headspace syringes – compared to the market standard – provide an excellent performance over a large temperature range for increased lifetime, lower cost of operations, and increased reproducibility of your headspace analysis. To provide additional robustness to your liquid sample analysis, HT2800T features the innovative SyringeID, a proprietary technology based on RFID tags. The SyringeID is able to identify syringes in an univocal way; thereby preventing errors when mounting a syringe, preventing syringe volume mismatching and keeps track of the syringe consumption. The SyringeID system is able to provide you with a level of confidence never previously achieved by identification systems based on syringe carriers.

OPTIONAL SOFTWARE CONTROL

The HT2800T can also be controlled by a PC, using the HTA Autosampler Manager (please see the dedicated brochure). HTA Autosampler Manager software can run in standard mode or with full CFR 21 Part 11 compliance.

Focus: SPME (Superior thermal stability)

The HT2800T 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).

Focus: LIQUID

The HT2800T 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 HT2800T 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.

Focus: HEADSPACE

The robotic vial processing operation allows for sample analysis in a straightforward 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 HT2800T 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. We offer the lowest cost of ownership in the market. No carrier gas is needed because gas is used only for purging between samples. No o-rings or seals to replace, saving hours of unnecessary downtime. No magnetic or special caps are required, because vial transport is positive and reliable.
