The advantages and working principle of the nitrogen blowing instrument 1.
It can process multiple samples at one time, and the advantages are more obvious in the repeated experiments of multiple factors and multiple levels
.
2.
The experimental operation is simple and flexible
.
The process of enrichment can be adjusted at any time by the accountant without restriction
.
3.
The operator does not need to maintain for a long time in the experiment, saving manpower
.
4.
The rotary evaporator may cause the loss of the sample when the solvent is boiling, while the nitrogen blowing instrument is accurate and sensitive in the concentration to avoid the loss of the sample
.
The principle of nitrogen blower There are two ways to speed up evaporation: strengthen the air flow around it and its temperature
.
Nitrogen is also an inactive gas and can also act as a barrier to oxygen and prevent oxidation
.
The nitrogen blowing instrument achieves the purpose of concentration through these principles
.
It rapidly, continuously and controllably blows nitrogen gas onto the heated sample surface, enabling rapid concentration of large quantities of samples
