Claims
- 1. A sample inspection system, comprising:
- receptacle means for containing only sample fluid with suspended particles, said receptacle means having an opening;
- a thermal energy generation source disposed within said receptacle means for providing the sample fluid in said receptacle means with a pulse energy to discharge a droplet of the sample fluid from the opening, each droplet containing a particle;
- a detector for detecting the particle; and
- a synchronizing circuit for synchronizing the discharge by said energy generator and the detection by said detector.
- 2. A sample inspection system, comprising:
- receptacle means for receiving only a sample fluid with suspended particles, said receptacle means having an opening;
- a thermal energy generation source disposed within said receptacle means for providing the sample fluid in said receptacle means with a pulse energy to discharge a droplet of the sample fluid from the opening, each droplet containing a particle;
- a transparent plate facing the opening, the sample fluid discharged from the opening being received on said transparent plate; and
- a detector for detecting the particle on said transparent plate.
- 3. A sample inspection system, comprising:
- receptacle means for receiving only sample fluid with suspended particles, said receptacle means having an opening;
- a thermal energy generation source disposed within said receptacle means for providing the sample fluid in said receptacle means with a pulse energy to discharge a droplet of the sample fluid from the opening, each droplet containing one particle;
- a detector for detecting the particle;
- a data storage memory for storing data detected by said detector; and
- a signal processor for analyzing the data stored in said data storage memory.
- 4. A system according to one of claims 1 to 3, wherein said thermal energy generation source includes a heater.
- 5. A system according to one of claims 1 to 3, further comprising a light source for irradiating the particle with light, wherein said detector detects scattered light or fluorescent light.
- 6. A system according to one of claims 1 to 3, further comprising a plurality of said receptacle means and said thermal energy generation source, with each of said receptacle means provided with one of said thermal energy generation sources.
