Working Principle

The basic principle of the nitrogen blowdown concentrator is to use nitrogen or other inert gases from the gas needle to blow to the sample liquid surface at a constant flow rate, while the heating module to provide a constant temperature environment, prompting the solvent to evaporate in a short period of time. Since the inert gas is not involved in the sample reaction, the concentration process can be carried out in an oxygen-free environment, effectively avoiding oxidative loss of target compounds. The whole machine stabilizes the temperature through the PID temperature control system, and the gas flow is precisely controlled through the flow regulating valve or rotor flowmeter to achieve repeatable and reliable concentration operation.
