- the supersonic jet flow passes between the jet generator and the differential exhaust chamber and between the differential exhaust chamber and the laser irradiation chamber. It is a mass spectrometer using the supercritical fluid jet method according to claim 5 provided with a mer.
- the supercritical fluid used in the present invention is carbon dioxide, nitrous oxide (nitrous oxide), fluorocarbon, and the like.
- the reason for using “supercritical fluid” such as carbon dioxide gas instead of “helium gas” as a fluid for dissolving a sample (hereinafter referred to as a carrier) is as follows.
- helium which is a gas
- the function of "dissolving" the sample is vaporized according to the inherent vapor pressure of the sample and becomes a mixed gas with helium.
- a normal gas such as helium gas
- the amount of "dissolution” of a sample related to the type of carrier is determined only by the saturation vapor pressure specific to each sample molecule.
- non-volatile sample molecules or molecular aggregates such as naphthol are not vaporized unless heated in helium.
- the sample can easily form a mixed gas with the gas carrier, the sample molecule or the molecular association in the lowest energy state can be obtained by the jet cooling method.
- gas carriers can not vaporize non-volatile materials without heating them. If the sample is a thermally decomposable substance, it will dissociate (decompose) if it is heated, so jet cooling using a gas carrier can not be applied to such a sample.
- supercritical fluids such as carbon dioxide gas have the property of being liquid, and have the ability of being a solvent that "melts out” sample molecules or molecular aggregates, which is different from a simple gas such as helium.
- a supercritical fluid the amount of “melted out” varies depending on the type of fluid and pressure, and also by the addition of a small amount of the above-mentioned additive (modifier).
- modifier a small amount of the above-mentioned additive
- Such a property can not be a gas such as helium.
- One of the major features of the present invention is that it utilizes the liquid-gas two-face nature of the supercritical fluid, and the nature of the liquid as a solvent for dissolving out the supercritical fluid sample and The property of the gas is used as the carrier gas at the time of jet injection in vacuum.
- non-electrolytic, thermally decomposable and thermally unstable samples are vaporized without heating to high temperatures and jet-cooled into vacuum, regardless of whether they are electrolytes or non-electrolyte molecules. It became possible to take it out.
- a supercritical fluid is a high pressure fluid over 100 atmospheres, it is placed in a high vacuum vessel.
- a device In order to perform jet injection, it is necessary to devise a device. Sufficient to obtain a jet cooling effect, it is necessary to keep the vacuum container to a vacuum degree of below 10- 4 Torr in a time jetting. If cost is neglected, it is better to use a force pulse valve to intermittently inject gas by injecting gas continuously using a pinhole and using a huge pump to evacuate the flowing gas at high speed.
- a pump with a low exhaust rate can achieve a sufficiently high degree of vacuum, and can reduce the consumption of gas, which is advantageous in cost.
- cooling does not mean cooling in a normal sense, that is, the temperature is low!
- temperature is a concept applied to thermal equilibrium, that is, a state that follows the Boltzmann distribution, and since the gas jetted into a vacuum is not a thermal equilibrium, the concept of temperature in the ordinary sense is not valid. Absent.
- the above “cooling” has two meanings, and the mechanism differs as follows.
- Another "cooling” is the cooling of molecular internal energy (vibration ⁇ rotational energy).
- the cooling of the molecular internal state occurs in the process in which the molecular internal energy is converted to the translational velocity of the carrier molecule by the inelastic collision of the sample molecule with the carrier molecule as it passes through the orifice. Therefore, the orifice diameter should be small in the sense of creating a large pressure difference, but if an orifice with a diameter smaller than the mean free path of the molecule is used, sufficient intermolecular collision will not occur when passing through the orifice. , The internal state of the sample molecule is not cooled. Such gas flow is called a leak jet.
- jet cooling converts various energy states into translational energy, and the internal energy states are monochromatized (the energy of light is determined by the wavelength or “color”. Generally speaking, not only light but also the alignment of energy states is called "monochromatization”.
- jet spray chamber 10 4 - 10 but 5 is a Torr vacuum degree of about, for the mass analyzer which is required a high degree of vacuum of about 10 7 Torr, to both the connection It requires a device. Furthermore, it is necessary to devise a point to introduce the supersonic jet flow obtained in the jet injection chamber into the mass analyzer while maintaining the jet cooling effect. Therefore, in the present invention, a differential exhaust chamber is provided between the jet generator and the mass analyzer, a skimmer is provided in the gas flow path between the jet generator and the differential exhaust chamber, and a differential exhaust chamber and mass spectrometry are further provided. A skimmer was also placed in the gas flow path between the vessels.
- a skimmer Unlike a normal pinhole, a skimmer has an opening with a sharp edge-like cross section at the tip of the skimmer, and therefore, the scattering of supersonic molecular beams when passing through the opening can be minimized. By preventing this, the jet-cooled gas is less susceptible to thermal excitation.
- the aperture diameter of the skimmer is determined by how much "thick" a molecular beam is required, and in the present invention, a laser focused on a molecular beam with a lens (the focal diameter is the number / zm In principle, a “thick” molecular beam of about the size of the focused diameter of the laser may be used to irradiate the light. However, it is difficult to manufacture a skimmer with a small aperture diameter, and the laser beam has a narrow molecular beam. In the present invention, a skimmer with an opening diameter of about 2 mm was used.
- the supercritical fluid can be treated with a small amount of additive (modifier) to improve the supercritical extraction ability, and a modifier of 0 to 25% by volume may be added. .
- the lower limit of the amount to be added can not be specified, but the upper limit is up to 25% by volume.
- adding a modifier of 25% by volume to the supercritical carbon dioxide results in 75 atm as carbon dioxide, which is higher than the critical pressure of carbon dioxide (if this pressure is higher than This is because the property as a fluid approaching 9 atm pressure decreases.
- a cluster in which a large amount of modifier molecules are attached to the sample molecules or the molecular association is formed, which causes an obstacle in mass spectrometry.
- the resonance multi-photon laser ion beam method can be applied by making the leak jet of the conventional SCF-mass method supersonic jet.

- the melting point of 1-naphthol used as a sample for verification experiments is 288 ° C, and a sample gas with a sufficient concentration can not be obtained unless heated before 100 ° C.
