To provide a sample manufacturing device for analyzing and measuring easily a micro component in a liquid with high sensitivity, even with a small amount of sample, in a real time, at the measuring site, and to provide a quartz microbalance analytical measuring instrument that uses the technique thereof.
A frequency is impressed to an inorganic ceramic 8 having a piezoelectric characteristic with an electrode 9 attached to a resonator 1, using a principle of ultrasonic vibration for detecting a micro substance contained in the liquid, the substance contained in the liquid is hydrogen-bonded or contained with one or more of water molecules, formed molecule aggregates are atomization-separated in the order of lightweight, the atomized substance is introduced into a quartz oscillator 5, and the frequency change of the quartz oscillator oscillating 5 stably by a quartz frequency impressing device 6 is thereby analyzed by a frequency change display 7 so as to precisely specify the substance.
