Product Information<\/h4>\n\n\n\n

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.<\/p>\n\n\n\n

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.<\/p>\n<\/div>\n<\/div>\n\n\n\n

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 \u03a610 mm x 30 mm sample including real bolt\/nut can be analyzed.<\/p>\n<\/div>\n\n\n\n

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.<\/p>\n\n\n\n
