Claims
- 1. A flow cell for a particle analyzer using an electrical sensing zone method, comprising:a detecting member having a through hole; a first cell for supplying a particle containing liquid to the through hole; a second cell for receiving and discharging the particle containing liquid that has passed through the through hole; electrodes provided in the first cell and the second cell respectively, for supplying an electrical current to the liquid passing through the through hole; and a sliding member for sliding at least one of the first and second cells to change a distance therebetween; wherein the first and second cells cooperate with the sliding member to detachably sandwich the detecting member therebetween so that the detecting member is connected to the first and second cells in a watertight state.
- 2. A flow cell according to claim 1, wherein the detecting member is adapted to be arranged between the first and second cells in a specific position.
- 3. A flow cell according to claim 1 further comprising a fixing member for fixing the at least one of the first and second cells to the sliding member.
- 4. A flow cell according to claim 1, wherein the detecting member includes an engaging portion for detachably engaging with the sliding member.
- 5. A flow cell according to claim 1, wherein the sliding member comprises a plurality of parallel shafts projecting from one of the first and second cells and the other cell has a plurality of openings which the shafts pass through.
- 6. A flow cell according to claim 5, wherein the detecting member includes a plurality of U-shaped grooves for detachably fitting with the plurality of parallel shafts, respectively.
- 7. A flow cell according to claim 6, wherein the plurality of U-shaped grooves have different widths, and the plurality of parallel shafts each have a sectional size that fits into the corresponding U-shaped groove.
- 8. A flow cell according to claim 1, wherein when the detecting member is spaced from the first and second cells by the sliding member, the detecting member having the through hole is replaceable with another detecting member having a through hole of a different diameter.
