Trapped air in pumps of Automatic amino-acid analyzer is eliminated us

1.	Trapped air in pumps of Automatic amino-acid analyzer is eliminated using which of the following ways?(a) Suction pump(b) De-aerator(c) Overcome naturally by pump pressure(d) Using pulse damperI have been asked this question in examination.I'm obligated to ask this question of Amino-Acid Analysers in section Chromatography of Analytical Instrumentation
Answer» Right ANSWER is (b) De-aerator Explanation: De-aerator is used to eliminate trapper air in PUMPS of an automatic amino-acid ANALYZER. Here, bubble-trap TYPE de-aerator is used.
