Liquefiable gas sampler is mainly used to convert high-pressure liquid gas into gaseous samples for subsequent analysis and testing. Its core functions include flash evaporation treatment and compositional gasification. By accurately controlling the flow rate, temperature, and pressure, it ensures that the composition of the sample after gasification is consistent with that of the liquid state. It is suitable for trace water analysis, chromatographic analysis, and other scenarios of liquid hydrocarbons.
Liquefiable gas sampling injector (flash evaporator) is a key equipment used for pre-treatment of liquid hydrocarbon substances before analysis. Its core function is to convert liquid samples into gaseous substances with equal composition, constant temperature, constant pressure, and controllable flow rate, in order to solve the problems in liquid hydrocarbon analysis.
Core functions and technical principles
Waiting to form gasification
In an equal diameter capillary space, liquid drips in at the evaporation rate and rapidly evaporates, pushing the tail of the previous droplet that evaporates into gas to flow rapidly, forming a high-speed airflow. This process has no separation opportunity or liquid storage, ensuring that the gas composition after gasification is consistent with the liquid state, especially suitable for the analysis of trace impurity components.
Flash evaporation gasification
By rapidly heating and evaporating liquid hydrocarbon samples with high-temperature and high-pressure steam, they are converted into gaseous hydrocarbon substances. This technology overcomes the discriminatory effect of room temperature gasification on low concentration high boiling point components, ensuring sample repeatability.
Constant temperature and pressure control
By using microcontroller control and mass flow controller, the flow rate is accurately measured to achieve stable control of temperature (adjustable from 0 to 230 ℃, accuracy ± 0.1 ℃) and pressure (pressure regulation control unit), meeting the requirements of analytical instruments for sample status.
