Product Features

  • 10-inch color touchscreen for online monitoring.

  • Simple operation with one-click sample analysis.

  • Semiconductor cooling eliminates liquid hydrogen requirements (cold trap temperature down to -35°C).

  • Real-time display of cycle times for all operational states.

  • Adjust injection volume via injection time for samples of varying concentrations.

  • Real-time display of set and actual temperatures for all channels.

  • Programmed temperature ramping: 8 steps, programmable.

  • Synchronized injection and data acquisition significantly reduce timing errors.

  • Fully automated operation for sampling, adsorption, desorption, injection, and backflush cleaning.

  • All tubing treated with inert gas technology.

  • Multiple methods stored for quick recall, enabling rapid startup and analysis.

  • Equipped with system leak detection capability.
