HTA 2000H Headspace Autosampler Overview
The HTA 2000H Headspace Autosampler is a static headspace sampling system designed for automated GC and GC/MS analysis of volatile and semi‑volatile compounds. It supports batch processing of up to 42 samples using a removable vial rack, enabling efficient handling of routine analytical workloads. Samples are conditioned through controlled vial heating and orbital agitation, followed by syringe‑based headspace extraction and injection. The system is commonly used in laboratories that require repeatable headspace sampling, reduced manual handling, and reliable unattended operation.
Available from Alliant Scientific, an authorized HTA distributor, supplying the HTA 3000A Automatic Liquid Autosampler with full support for system configuration, installation.

FAQ
- What type of sampling does the HTA 2000H perform?
The HTA 2000H is designed for static headspace sampling, where volatile compounds are extracted from the headspace above a sample prior to GC or GC/MS analysis. - How many samples can be processed in one sequence?
The system supports up to 42 samples loaded in a removable vial rack, enabling extended batch runs. - What vial sizes are supported?
The HTA 2000H is typically used with 20 mL vials, with optional support for smaller vial sizes depending on configuration. - Is the system suitable for unattended operation?
Yes. The HTA 2000H is commonly used for unattended and overnight analytical runs once a sequence is programmed. - What types of laboratories use this autosampler?
The HTA 2000H is used in environmental, food and beverage, petrochemical, pharmaceutical, quality control, and contract laboratories performing routine headspace analysis.
