Custom GC Autosampler We have the autosampler to fit your needs HTA’s GC autosampler offering is the widest and the most complete in the market: we offer six models to answer different needs in terms of injection techniques - standard liquid injection, headspace or solid-phase microextraction (SPME) - and sample capacities - from 15 to in excess of 200 samples. Despite our wide range, we recognize that laboratories occasionally have needs that do not find an answer in the standard autosampler models offered by HTA or their GC manufacturer. In the past - when those special needs arose - laboratories were obliged to perform manual injections or to opt for expensive and complex all-in-ones autosamplers that – besides offering the required automation – include and charge for functionalities that are not needed. Now we offer you the final and most effective solution for your custom needs: a custom autosampler! HTA’s custom autosamplers offer affordable pricing and the same level of robustness and reliability of a standard autosampler. In fact, our autosampler platforms (HT2000, HT3000, HT4000) have been designed to allow us flexibility in accommodating many different requests and customizations – both hardware and software - without any major effort. Furthermore, our LEAN production system – based on cellular manufacturing - allows us to generate product variety. Learn below how we can customize your autosampler. HEAT, COOL OR VORTEX Your GC autosampler can be customized to execute simple sample preparation tasks before the injection, according to your specific needs. The sample vessel market standard for GC autosamplers is 2, 10 and 20ml vials. However, you may consider using nonconventional sample vessels to avoid the high cost of sample reformatting: reduce error, reduce cost and improve throughput! You may need to heat the sample to a certain temperature (for example, because it is a necessary condition for a chemical reaction). In this case, the vial heater module can be integrated into your autosampler: the sample is transferred into this module and the reaction can then take place. Furthermore a vortex station can be included in your autosampler to perform effective mixing of samples and standards, to assist solubilization or to guarantee the representativeness of the injected sample. The whole sample rack can also be cooled to preserve samples from thermal degradation and to avoid undesirable phase changes. The preparation of a sample can be executed while the previous sample is being analyzed, to optimize the timing and increase throughput. We have great experience of using nonconventional sample vessels for special applications: contact us and inquire about custom racks. By equipping your autosampler with a custom rack, you will be able to run the sample vessels as they come from your production line or sample preparation process. If the volume of your sample vessels is larger than standard, you may also need a higher solvent capacity and a consequently higher waste capacity. Also in this case we can meet your needs offering you a solution including larger solvent and waste reservoirs. HTA - SAMPLING FOR SCIENCE | www.hta-it.com

Vortex-Heater station Infinite waste & nozzle for large solvent requirement FLOW CELL Collect your sample directly from the line though the use of a flow cell. You will then be able to inject your sample at timely intervals into your GC or GC-MS system. You may also consider collecting samples from the line, injecting part and storing the remainder in a vial as double in case further tests are needed. SIMULTANEOUS INJECTION FOR SIMDIST & OTHER APPS Like in a synchronized swimming duet, our autosamplers can be used – without Transfer line modification - to perform simultaneous injections. You...
