A pipelining assembly for use in a blood analyzing instrument, methods for performing parallel pipelining functions, and methods for processing a plurality of prepared blood samples through a blood analyzing instrument. The pipelining assembly presented generally includes a first sample preparation chamber, a first queuing chamber in fluid communication with the first sample preparation chamber, and a first control valve between the first sample preparation chamber and the first queuing chamber. The pipelining assembly further includes a second sample preparation chamber, a second queuing chamber in fluid communication with the second sample preparation chamber, and a second control valve between the second sample preparation chamber and the second queuing chamber. An analysis chamber is provided to receive first and second prepared blood samples from the in first and second queuing chambers. The presented methods include steps for repeated processing of prepared blood samples through the blood analyzing instrument.

1. A method of processing a plurality of samples through an instrument, the method comprising: (a) transferring a first sample from a first chamber to a second chamber through a first control valve;(b) closing off the first control valve, opening a second control valve, and applying a pressure to a first port of the second chamber to transfer an aliquot of the first sample from the second chamber through the second control valve to an analysis chamber for analysis;(c) opening a third control valve to transfer a second sample from a third chamber to a fourth chamber through the third control valve, wherein step (c) is performed substantially concurrently with step (b);(d) transferring an aliquot of the second sample from the fourth chamber to the analysis chamber for analysis;and(e) cleaning the first chamber substantially concurrently with step (b). 2. The method of claim 1, further comprising (f) delivering a fluid to the first port to clean the first chamber. 3. The method of claim 1, wherein step (e) is performed substantially concurrently with step (d). 4. The method of claim 1, wherein step (e) is performed concurrently with step (c). 5. The method of claim 1, wherein step (e) is performed substantially concurrently with step (b). 6. The method of claim 1, further comprising: (f) transferring a third sample from the first chamber to the second chamber, wherein step (f) is performed concurrently with step (d). 7. The method of claim 6, further comprising: (g) cleaning the third chamber, wherein step (g) is performed substantially concurrently with step (d). 8. The method of claim 7, further comprising: (h) transferring a fourth blood sample to the third chamber, wherein step (h) is performed substantially concurrently with step (d). 9. A method of processing a plurality of samples through a particle analyzing instrument, comprising: (a) transferring a first sample from a first sample preparation chamber to a first queuing chamber through a first control valve;(b) transferring an aliquot of the first sample from the first queuing chamber to an analysis chamber for analysis by applying a first pressure to the first queuing chamber through a first port and closing off the first control valve, wherein the first port and the first control valve are in connection with the first queuing chamber;(c) transferring a second sample from a second sample preparation chamber to a second queuing chamber by applying a second pressure to the second queuing chamber through a second port and opening a second control valve, wherein the second port and the second control valve are in connection with the second queuing chamber;(d) transferring an aliquot of the second sample from the second queuing chamber to the analysis chamber for analysis, wherein step (c) is performed substantially concurrently with step (b); and(e) cleaning the first sample preparation chamber, wherein step (e) is performed concurrently with step (b). 10. The method of claim 9, wherein the first pressure is a positive pressure. 11. The method of claim 9, wherein the second pressure is a negative pressure. 12. The method of claim 9, wherein the first port and second port are located at the top of the first queuing chamber and the second queuing chamber, respectively. 13. The method of claim 9, further comprising: (f) cleaning the second sample preparation chamber;(g) upon completion of step (b), cleaning a path between the analysis chamber and the first queuing chamber;(h) cleaning the first queuing chamber;(i) upon completion of step (d), cleaning a path between the analysis chamber and the second queuing chamber; and(j) cleaning the second queuing chamber. 14. The method of claim 13, wherein step (d) is performed substantially concurrently with step (f). 15. The method of claim 13, wherein step (d) is performed substantially concurrently with step (h). 16. The method of claim 13, further comprising: (k) transferring an aliquot of a third sample to the first queuing chamber. 17. The method of claim 16, wherein step (k) is performed substantially concurrently with step (d). 18. The method of claim 13, further comprising: priming the path between the first queuing chamber and the analysis chamber prior to step (b). 19. The method of claim 13, further comprising: priming the path between the second queuing chamber and the analysis chamber prior to step (d). 20. The method of claim 9, wherein the samples are biological samples containing particles and cells.
