Изобретение относитс  к газовой хроматографии и может найти примене-. нйе дл  поддержани  заданного .температурного режима работы хроматографических колонок при анализе смесей органических и неорганических веществ .The invention relates to gas chromatography and can be used. to maintain the desired temperature of the chromatographic columns when analyzing mixtures of organic and inorganic substances.

Известен термостат дл  газового хроматографа, содержащий корпус, рабочую камеру, образованную пр моугольным металлическим коробом, слой теплоизол ции, размещенный между пр моугольным металлическим коробом и корпусом, нагреватель и турбину дл  перемешивани  воздуха в рабочей камере , размещенные в рабочей камере, крышку с механизмом ее перемещени A gas chromatograph thermostat is known, comprising a housing, a working chamber formed by a rectangular metal duct, a thermal insulation layer placed between a rectangular metal duct and a housing, a heater and a turbine for mixing air in the working chamber, placed in the working chamber, a lid with a mechanism moving

Недостатком известного термостата  вл етс  сложность его конструкции , обусловленна  специальной конструкцией крышки термостата, снабженной механизмом ее автоматического открывани  в момент, предшествующиеThe disadvantage of the known thermostat is the complexity of its design, due to the special design of the thermostat cover, equipped with a mechanism for its automatic opening at the moment preceding

охлаждению хроматографических колонок , размещенных в рабочей камере. Кроме того, при работе в режиме программировани  температуры, когда после завершени  цикла хроматографического анализа необходимо охладить колонки до температуры, близкой к комнатной температуре, требуетс  значительное врем  вывода хроматографа на режим.cooling of chromatographic columns placed in the working chamber. In addition, when operating in the temperature programming mode, when, after completing the chromatographic analysis cycle, it is necessary to cool the columns to a temperature close to room temperature, a considerable time is required for the chromatograph to be brought to operation.

Это обусловлено тем, что при открытой крышке термостата необходимо за счет принудительной вентил ции не только отладить внутренний объем термоСтата , но и сн ть тепло со сло  This is due to the fact that, with the thermostat lid open, it is necessary, due to forced ventilation, not only to debug the internal volume of the thermostat, but also to remove heat from the bed.
