II (7) so that purge gas pass through the first input pipe (42) with the passage for connecting of the second efferent duct (53) in extraction flask (1)
Packaging material for food purging 5min, by switching multiple-way valve I (6) and multiple-way valve II (7), interactively pick-up 30min,
Step 3, air lift extract is respectively by the second input pipe (43) and the passage for connecting and first of the first efferent duct (52)
Input pipe (42) enters absorber (2) with the passage for connecting of the second efferent duct (53), is extracted agent absorbent,
Or its step is as follows：
Step one, takes 0.5000 gram of soil and is put in extraction flask 1, adds 1mL acetonitriles absorbing liquid to wave to extract in absorber (2)
The property sent out aldehyde compound,
Step 2, opens nitrogen, and heating sample bottle is to 250 DEG C so that purge gas are defeated by the second input pipe (43) and first
The passage of the connection of outlet pipe (52) purges 5min to the soil of extraction flask 1, adjusts multiple-way valve I (6) and multiple-way valve II (7) so that
Purge gas are purged with the passage for connecting of the second efferent duct (53) by the first input pipe (42) to the soil of extraction flask (1)
5min, by switching multiple-way valve I (6) and multiple-way valve II (7) interactively pick-up 30min,
Step 3, air lift extract is respectively by the second input pipe (43) and the passage for connecting and first of the first efferent duct (52)
Input pipe (42) enters absorber (2) with the passage for connecting of the second efferent duct (53), is extracted agent absorbent,
Or its step is as follows：
Step one, takes 0.5000 gram of phenoplasts and is put in extraction flask (1), and 1mL0.1M NaOH is added in absorber (2)
With the ammonia that absorbing phenolic plastics are discharged,
Step 2, opens carrier gas helium so that purge gas are connected by the second input pipe (43) and the first efferent duct (52)
Passage 30min is purged to the phenoplasts of extraction flask (1),
Step 3, air lift extract is entered respectively by the second input pipe (43) with the passage for connecting of the first efferent duct (52) to be inhaled
Device (2) is received, agent absorbent is extracted.
