Interface detection and control systems and method |
摘要 |
A viewing area in a blood separation chamber is monitored for the presence of an interface region between plasma and cellular blood components. Sensed optical density values for the viewing area are compared to a calibrated threshold value to generate a time pulse output. A calibration element derives the calibrated threshold value based upon either (i) a comparison of a sensed reference optical density value in the viewing area to an expected optical density value for the reference material, or (ii) a sensed optical density value of plasma exiting the blood separation chamber, or both.
