HTA's proven superior headspace technology is based on a high performing gastight syringe. Through a short flow path, it eliminates any source of error, such as vial pressurization, valve switching, loop filling or transfer lines assuring repeatability (RSD up to <1%), minimal carryover and continuity of the operations.
To obtain the highest sample throughput, the progressive sample transfer into the oven assures that one sample is heated while the previous one is analyzed. As a consequence, the waiting time between each run is avoided. Up to 6 vials can be heated simultaneously in the oven. HT2000H allows sequential injections even of samples featuring highly dissimilar characteristics and it permits adjustable sample volumes without loop changes.
Moreover, vial leakage check – a proprietary technology - 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.
