HTA HT2000HT High Temperature Headspace Autosampler for GC

HT2000H Series Headspace Autosamplers

HT2000HT Headspace Autosampler - 42 samples: 20, 10 or 6 ml Sample Capacity

Extend support to HighTemperature applications

• Fits all GCs and GC/MS • Easy to use • Shaker included • CFR 21 Part 11 • The ideal choice for polymer analysis • Sample incubation temperatures up to 300°C 

HT2000HT features an upper sample heating temperature of 300°C: it enables the execution of high-temperature headspace applications in a syringe-based system, therefore without the constraints and limitations induced by valve&loop systems.

HT2000HT incubation oven offers a 3-position heating and shaking chamber, allowing the simultaneous incubation of multiple samples. The incubation temperature can be set between 40° and 300°C to accommodate the widest range of applications: the system can handle standard headspace applications (that require temperatures lower than 150°C) while still being well-suited to special high-temperature applications that include analysis of high-boiling compounds, such as phthalate esters or cyclic siloxanes, and polymers. HT2000HT is the perfect instrument for quality control of chemical product materials and for heat-induced degradation studies.

KEY FEATURES

OPERATIONS

The robotic vial processing operation allows for sample analysis in a straightforward and systematic way. The sample vials are transported into the heated incubator for preconditioning. The sample is simultaneously heated and shaken, in order to facilitate the state change and to reach the equilibrium. A heated, gas-tight syringe is then moved over the incubator and the headspace sample is withdrawn.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 user places the sample vials in the tray. The vials are picked up by the autosampler gripper and placed in the oven where they are simultaneously heated and shaken in order to facilitate the state change and to reach equilibrium. Then, the syringe aspirates the head space vapors from each vial and injects them into the GC injector. Finally, the vials are automatically put back in the tray while a syringe cleaning procedure is activated. To obtain the highest sample throughput, up to 6 vials can be heated simultaneously in the oven.

PROVEN SUPERIOR TECHNOLOGY

The high performance, gas-tight heated syringe is a simple and robust system. It eliminates the dead volume and absorption effects, typical of sample loops and transfer lines, which can also impede their detection at very low levels. The HTA syringeonly 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. No complicated error prone operations, such as vial pressurisation, valve switching, loop filling or heated transfer lines are involved. Therefore, you can extract more data from the samples in less time and at the lowest possible cost per sample. Vial leakage check - a proprietary technology1 - can be included in your method. In such a scenario the pressure inside vials of the same batch is monitored by an heuristic procedure in order to check against anomalous values that are indicative of a vial leakage problem. Finally, to provide additional robustness of your analysis, going beyond preventive maintenance counters, a system integrity test1 can be automatically performed in every in every batch by means of an heuristic procedure.

THE LOWEST COST OF OWNERSHIP, THE GREENEST CHEMISTRY

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. Allows you to instruct the system to shut off heating when the run is completed, in order to reduce electrical consumption.

USER-FRIENDLT TOUCH SCREEN

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. For routine analyses, the headspace sampler features a one-touch operation: after loading the samples, you just need to push the START button.

VIAL LEAKAGE CHECK AND SYSTEM INTEGRITY TEST

To provide additional robustness for your analysis, HT2000H includes important functionalities such as the preventive maintenance counters, a system integrity test - that can be automatically performed at every batch - and the vial leakage check - a proprietary technology, based on an heuristic procedure, to spot vial leakage problems.

UNIVERSAL AND VERSATILE HTA

Headspace Autosamplers are the most compact on the market (with a near-to-zero requirement for bench space, as well as no requirement for GC injector modification). They can serve both the front and rear injector in most supported GCs. The injector selection is made directly by the sequence list, avoiding difficult set up operations or re-installation to pass from one injector to the other. Furthermore, the rotating head design ensures that the injection port is always free, for manual injections or maintenance. The system is fully selfcontained and can be interfaced with almost any gas chromatograph, giving you access to HTA’s proven headspace technology, regardless of the GC brand or model you have in your laboratory.

OPTIONAL SOFTWARE

The HT2000H series can 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. HTA Autosampler Manager software also includes a dedicated panel for method development: progressive tests can be implemented in a very convenient way so that successive samples receive incremental changes in method parameter setpoints for time and temperature.
