Sample ashing device having quick warming and intelligent temperature control function

Abstract

The invention relates to a sample ashing device having a quick warming and intelligent temperature control function. A multi-position sample tube frame is provided with a ventilated gas needle cover, gases such as air or oxygen can be led in during sample ashing, and a sample ashing speed is quickened. The sample tube frame is placed on a liftable sample tube frame table, and the height of the liftable sample tube frame table can be freely adjusted, so that the position of a heating area where samples are located is changed. A temperature sensor can monitor temperature in real time, output power of a light wave heating pipe is adjusted, and the temperature control precision is improved. A temperature control mode can be input from a color touch screen and can also be controlled remotely through a network from a mobile phone or a computer client, and labor intensity is reduced. Concentrated heating is performed on the sample part in the form of taking a gold plating light wave heating pipe as a heating element and taking a light wave heating pipe with a reflecting layer as radiant energy, so that electric energy is saved. An integrally formed ceramic fiber heat-insulating liner serves as a heat-insulating cavity, precise temperature control is performed in real time, and remote monitor is performed. The sample ashing device is quick in warming speed, greatly improves working efficiency and saves energy.

Description

technical field [0001] The invention relates to a heating device capable of rapid and high-temperature ashing of samples, in particular to a sample ashing device for rapid temperature rise and intelligent temperature control. Background technique [0002] The detection of various trace elements in organic matter samples in food, environment, life science and other fields has attracted more and more attention from the whole society. Before the determination of various trace elements by analytical instruments, most of the samples must be pre-treated to make the heavy metal elements inorganic and transferred into a liquid solution. According to data reports, the current dry ashing method is an important method in the analysis work. [0003] Judging from the current technological development status, the dry ashing method is mainly based on manual operations, and the main equipment used includes electric heating plates, muffle furnaces and conventional utensils, and there are ma...
