近几年来,由辽宁省农科院研制的LNK—801A型远红外消煮炉已被许多实验室应用。该设备适合于大批样品的消煮处理,效率较高,受到分析工作者的欢迎。但该设备仍然需要占用一个操作人员,并经常根据样品的消煮情况采取不同的操作,给使用带来麻烦。为此,作者对消煮炉加一个控温装置而使操作极为方便。由于消煮温度恒定可控,反应条件保持一致,测定精度也有所提高,现具体介绍如下: 本装置只要增加一只控温仪表,一只热电偶和一只交流接触器。热电偶插到消煮炉的加热孔内,通过导线与控制仪表相应端子
In recent years, developed by the Liaoning Provincial Academy of Agricultural LNK-801A far-infrared cooking stove has been many laboratory applications. The device is suitable for a large number of sample digestion and treatment, higher efficiency, analysts welcome. However, the device still needs to occupy an operator, and often takes different actions according to the de-boil condition of the sample, which brings trouble to use. For this reason, the author adds a temperature control device to the decocting furnace to make the operation extremely convenient. As the constant temperature controllable brewing, the reaction conditions remain consistent, the measurement accuracy has also increased, the specific introduction is as follows: The device as long as the addition of a temperature control meter, a thermocouple and an AC contactor. The thermocouple is inserted into the heating hole of the digestion furnace, and the corresponding terminal of the control instrument is connected through the wire
