    摘要： The invention provides an anesthesia monitor being able to directly make a separation and a determination in a real time of all components of a gas in which components having the same integer molecular weight exists an expiration and an inspiration as an analyzing object. The monitor has a small size, a low price and a operational facility. A microscopic quantity of the expiration gas is introduced from a circular route of an anesthesia circuits (31) for an inhalation anesthesia to the anesthesia monitor (1) through a material pipe-line (44). A material gas is transmitted by a rotary pump (48) through valves (46, 47) and opening and closing valve (51) to a measurement cell within a vacuum chamber arranged in a gap of magnetic poles of permanent magnets in a Fourier transformation mass analyzer so that the expiration gas is subjected to a high speed sampling. An ionization of the ions is carried out within the measurement cell. A cyclotron resonance is caused thereby causing a high frequent voltage which is received by receiving electrodes of the cell. After a digitalization of the signals, a computer executes a Fourier transformation mass analyzing process.
