HTDS-004
Thermal Desorption Spectroscopy (TDS) System for highly sensitive Hydrogen
Product Information
The HTDS-004, the newest model, has improved operability, making it even safer and easier to operate than previous models for high-sensitivity quantitative analysis of hydrogen content. The system is equipped with a sample transfer mechanism, sample loading chamber, analysis chamber, and analyzer which are based on ultra-high vacuum specifications. The hydrogen background pressure in the analysis chamber is reduced to 5.0E-9 Pa or below, enabling high-sensitivity analysis down to 0.01 wt.ppm. In addition, the one-click, step-by-step operation following the navigation function on the PC screen allows even a beginner to operate the system safely and simply.
Features
■Analysis Chamber
■Sample Heating Chamber
Two turbomolecular pumps in tandem reduce the Hydrogen background enabling highly sensitive real-time Hydrogen analysis.
The external heating type furnace and quartz core tube has no outgassing from the heater. This core tube connects directly to the analysis chamber, enabling a very low Hydrogen background (Hydrogen partial pressure) level of 5.0E-9 Pa or less. Compact design for a small sample with 100 mm uniform heating length.
■Sample Loading Chamber
■Build-in Hydrogen Standard Leak System
Replacing the sample is performed without exposing the analysis chamber and tube furnace to atmosphere. Pump-down time for sample transfer is 15 minutes or less. Pull-out flange provides easy and secure loading of the sample on the sample transfer rod. Up to Φ10 mm x 30 mm sample including real bolt/nut can be analyzed.
Hydrogen gas is automatically filled to each required pressure to ensure obtaining quantitative standards providing stable measurement results from sample to sample over a long period.
■Desiccator
Use as a storage box for samples in low-humidity conditions.
■“H2Cal” Hydrogen content calculation software
Internally-developed software calculates hydrogen content in wt. ppm.
■Pumping and Heating Control
Pumps, valves, and heating control are operated easily by the software. Standard leak gas introduction, which is required for quantitative standards, can be done with one click in the software.
