Unattended Liquid Sample Monitoring and Liquid Sample Storage System: 6,553,319

An unattended, self-calibrating, microprocessor controlled, electromechanical liquid sample acquisition, analysis and storage system is contained in a sealed evacuated housing. Liquid is drawn by suction into the sealed evacuated housing where it passes through a microfluidic manifold assembly to be brought into contact with signal producing liquid condition sensors. A marker solution is used to demarcate samples of liquid stored in an evacuated capillary. The microprocessor stores the signals produced by the liquid condition sensors and allows for cross-referencing the stored signals with the stored liquid samples in the capillary.
