HTA HT2000H Headspace Autosampler for GC *DISCONTINUED REPLACED BY 2000H*

HT2000H Series Headspace Autosamplers

42 Sample Capacity: 20, 10 or 6 ml vials

Made to meet the needs of static headspace injection for GC analysis.

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

Designed to satisfy the most demanding needs of robustness and ease of use, the HT2000H represents the ideal solution for headspace injection in GC and GC-MS analysis.

Just load the samples and run the analysis with no extra downtime. The full-colour 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 OneTouch operation. After loading the sample, you just need to enter a range of vial numbers and push the START button. The display shows real-time status and allows for easy stand-alone operations. 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, HT2000H is equipped with six-position oven that allows the optimization of preparation times.

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 vapours 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 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. 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.

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 self-contained 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.
