LI-2100 Automatic vacuum condensation extraction system

From

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 water extraction from plants and soil, overcoming the complexity of traditional liquid nitrogen cooling. Not only does it prevent isotope fractionation, but it is also safe and efficient, and it will not damage plants and soil. It can be used for water stable isotope measurement by a water isotope laser analyzer and a mass spectrometer

Hydrogen and oxygen stable isotopes in different water bodies can be used to study the sources of plant water use, water vapor transport, soil water migration and recharge mechanisms, recharge sources and ground water dynamics, water evaporation, the distinction between plant transpiration and soil evaporation, runoff formation and convergence, and there construction of paleoclimate. Therefore, it has attracted wides preadattention from hydrologists, ecologists,and climatologists.
