Preferably, in step S2, the heating temperature of the heating device 12 is 60 to 70 ℃, so as to accelerate the mixing effect. Of course, the heating temperature of the heating device 12 may also be considered as the case may be.
Preferably, in step S3, the port position of the hard infusion tube 15 is always kept at a position 0.5-1 cm above the layered position detected by the chromatograph 121, so as to ensure accurate extraction of the supernatant. Of course, the port location of the rigid infusion tube 15 may also be considered as the case may be.
The foregoing embodiments are merely illustrative of the principles of the present invention and its efficacy, and are not to be construed as limiting the invention. Any person skilled in the art can modify or change the above-mentioned embodiments without departing from the spirit and scope of the present invention.
