Abstract
The invention relates to a method for automatically examining a liquid sample, which has a liquid and at least one particle, by means of a first measurement signal which emanates from a liquid region and which serves to determine at least one particle with a first property, and by means of a second measurement signal which emanates from the liquid region and serves to determine at least one particle with a second property, the first measurement signal and the second measurement signal being evaluated independently of one another and whether a particle condition has been satisfied in the liquid region subsequently being determined on the basis of the evaluated first measurement signal and the evaluated second measurement signal.
Claims20
A device for examining a liquid sample including a liquid and at least one particle, the device comprising:
- a detection device that detects a first measurement signal emanating from a liquid region of the liquid sample, by means of which at least one particle having a first property can be determined, and that detects a second measurement signal emanating from the liquid region, by means of which at least one particle having a second property can be determined;
- an evaluation device which evaluates the first measurement signal and the second measurement signal independently of one another and determines whether a particle condition is satisfied in the liquid region based on the evaluated first measurement signal and the evaluated second measurement signal;
- a dispenser for dispensing the liquid sample;
- an actuating means for actuating the dispenser to eject a drop of the liquid sample from the dispenser;
- and
- a control device which controls a dispensing process depending on whether the particle condition is satisfied and determines a deposit location for the drop of the liquid sample to be dispensed, wherein the deposit location depends on whether the particle condition is satisfied.
A device for examining a liquid sample including a liquid and at least one particle, the device comprising:
- a detection device that detects a first measurement signal emanating from a liquid region of the liquid sample, by means of which at least one particle having a first property can be determined, and that detects a second measurement signal emanating from the liquid region, by means of which at least one particle having a second property can be determined;
- and
- an evaluation device which evaluates the first measurement signal and the second measurement signal independently of one another and determines whether a particle condition is satisfied in the liquid region based on the evaluated first measurement signal and the evaluated second measurement signal, wherein when determining whether the particle condition is satisfied, the evaluation device checks whether the particle determined by means of the first measurement signal and the particle determined by means of the second measurement signal are the same particle, wherein the evaluation device determines that the particles determined by means of the first and second measurement signals are the same particle when the location of the particle determined by means of the first measurement signal corresponds to the location of the particle determined by means of the second measurement signal.
A device for examining a liquid sample including a liquid and at least one particle, the device comprising:
- a detection device that detects a first measurement signal emanating from a liquid region of the liquid sample, by means of which at least one particle having a first property can be determined, and that detects a second measurement signal emanating from the liquid region, by means of which at least one particle having a second property can be determined;
- and
- an evaluation device which evaluates the first measurement signal and the second measurement signal independently of one another and determines whether a particle condition is satisfied in the liquid region based on the evaluated first measurement signal and the evaluated second measurement signal, wherein when determining whether the particle condition is satisfied, the evaluation device checks whether the particle determined by means of the first measurement signal and the particle determined by means of the second measurement signal are the same particle, wherein the evaluation device determines that the particles determined by means of the first and second measurement signals are the same particle based on a distance between the particle determined by means of the first measurement signal and the particle determined by means of the second measurement signal being smaller or larger than a limit value.
A non-transitory computer readable medium comprising programmed instructions that, when executed on a processor, cause the processor to:
- receive a first measurement signal, which emanates from a liquid region and serves to determine at least one particle with a first property;
- receive a second measurement signal, which emanates from the liquid region and serves to determine at least one particle having a second property;
- evaluate the first measurement signal and the second measurement signal independently of one another;
- determine whether a particle condition has been satisfied in the liquid region based on the evaluated first measurement signal and the evaluated second measurement signal;
- determine a deposit location for a drop of the liquid sample to be dispensed, wherein the deposit location depends on whether the particle condition is satisfied;
- and
- control an actuating means of a dispenser for dispensing the liquid sample to eject the drop of the liquid sample from the dispenser into the deposit location.
