LI-2100 Fully Automatic Vacuum Condensation Extraction System

LI-2100 Fully Automatic Vacuum Condensation Extraction System

The stable isotopes of hydrogen and oxygen in different water bodies can be used for research on plant water use sources, water vapor transport, soil water transport and replenishment mechanisms, replenishment sources and groundwater mechanisms, water evaporation, differentiation of plant transpiration and soil evaporation, formation and convergence of runoff, reconstruction of paleoclimate, and other aspects. Therefore, it has attracted widespread attention from hydrologists, ecologists, and climatologists. But the question is: how to extract water from plant xylem and soil without fractionation before conducting water stable isotope testing?

LI-2100 is a fully automatic vacuum condensation extraction system independently developed by LICA and has passed CE certification. It fundamentally solves the problem of extracting water from plants and soil, overcomes the complexity of traditional liquid nitrogen cooling, not only prevents isotope fractionation, but also is safe and efficient, without causing damage to plants and soil. Can be used in conjunction with LGR water isotope analyzer and mass spectrometer. Many scientists have conducted numerous studies combining LI-2100 and LGR water isotope analyzers.

Since its development and production, LI-2100 has sold nearly a hundred units in China, and domestic researchers have published numerous literature using this instrument, receiving numerous positive reviews from users.

With the widespread application of LI-2100 in China and the publication of numerous literature, some foreign scientists have also begun to pay attention to the LI-2100 developed and produced by Lijia Company. Lijia Company has also actively promoted this product overseas, thus opening the prelude for LI-2100 to go global and expand overseas.

working principle:This device adopts the principle of ultra-low pressure vacuum distillation freezing, which heats and distills the moisture in the sample in an ultra-low pressure environment, condenses and collects it in a low-temperature environment, thereby achieving the extraction of moisture without fractionation. The system mainly consists of an ultra-low pressure system, a heating system, a refrigeration system, and a control system. The entire process is automatically completed under the monitoring of the control system.
