Purge and Trap Sampler, PT-2 (CAT#: STEM-C-2750-ZJF)

The PT-2 is capable of purging liquid or solid samples. Its operation is similar to Tekmar, OI, and CDS instruments. It can be upgraded to a fully automatic solid-liquid sampler by adding an automatic sampler.

LCD display, simple operation, one-button startup.
Equipped with a high-energy infrared heater for the sample purging tube, ensuring fast heating rates and improved sensitivity.
Includes a sample defoaming device to automatically eliminate foam and prevent contamination of the gas path.
Utilizes imported high-inertness deactivation tubing for all sample transfer lines, ensuring no residue or cross-contamination and guaranteeing sample injection repeatability and accuracy.
Offers the flexibility to replace various trapping traps according to user requirements, accommodating all types of analyses.
Features a water trap to effectively remove water vapor from the sample, minimizing its impact on chromatography.
Employing a six-port valve configuration to minimize dead volume and ensure precise sample injection.
Connection points between the six-port valve and transfer lines are located within a heated insulation box, eliminating cold spots and preserving sample integrity.
All operations are driven by motors, eliminating the need for external driving gases and ensuring safety and convenience of use.
Equipped with multiple fault diagnosis and handling modes, automatically stopping operation and providing prompts in case of mechanical abnormalities to ensure reliable high-precision operation and prevent damage.
Highly compatible, easily connectable to various gas chromatographs and mass spectrometers domestically and internationally, capable of synchronizing chromatograph and workstation startup, and able to read chromatograph-ready signals for coordinated operation.
Pre-installed with multiple analysis methods at the factory, which users can modify and store as needed.
Equipped with a standard RS232 interface for remote control via a workstation.
Offers the option to select six-port valves with different working temperatures according to customer requirements.
Expandable to accommodate 30 or 120 position automatic injectors for water or water/soil analysis.
