    Evaluación de carbono en ecosistemas terrestres en Tizimín, Yucatán, México by García García, Dora Alicia

    Published 2019
    “…The twigs were separated to place them in paper bags with a capacity of 3 kg, identify them with a code and they will be processed in the weight of each of them, 3 subsamples of each tree will be obtained the answers of the Carbon Laboratories, Technology Laboratory of the Wood and Laboratory of Chemistry of the Faculty of Forestry Sciences of the Autonomous University of Nuevo Leon, where the samples are at a temperature of 75 ° C in a digital drying oven brand Riossa model HCF-102-D for 72 hours . For the total carbon concentration was performed with an analytical equipment called Solids TOC Analyzer model 1020A of O. l Analytical; it determines the concentrations in solid samples by complete combustion, at a temperature of 900 ° C, the gases produced by combustion are measured through a non-dispersive infrared detector that counts the carbon molecules contained in these gases; The wood, leaves and twigs subsamples were pulverized in a Marathon Electric mill series C20J020016. …”
