SEMI-AUTOMATIC DEVICE FOR THE EVAPORATION OF SOLVENTS BY ANALYTICAL GAS FOR CONCENTRATION OF ATMOSPHERIC SAMPLES, WHICH IS DESIGNED TO IDENTIFY AND QUANTIFY ORGANIC CHEMICAL COMPOUNDS WITH TOXIC PROPERTIES |
摘要 |
Device, system and operation method to perform functions in a semiautomatic manner, which permits the most favorable condition to evaporate a plurality of environmental samples that are diluted in solvents, by means of gas sweeping, preferably nitrogen, and a control electronic system that permits the superficial evaporation of the solvent thanks to exposing a cold sample kept at a constant temperature to a controlled gas flux. Furthermore, safety measures are considered to protect the extract, such as: acoustic and luminous signals that inform when it has been reached a critical moment in the process, reduction of gas flux during the last stage of the evaporation and valves to completely shut off the gas flux if a determined time period is exceeded. |
