SYSTEM AND METHOD FOR AUTOMATED REPEAT SEQUENCING

A method for sequencing a target polynucleotide includes detecting a first series of nucleotide incorporations complementary to at least a portion of the target polynucleotide. The first series of nucleotide incorporations forms a first complementary polynucleotide. The target nucleotide is secured to a substrate disposed in a sequencing zone of an assembly. The method further includes moving the substrate to which the target nucleotide is secured to a templating zone of the assembly; removing the first complementary polynucleotide when the substrate is disposed at the templating zone of the assembly, the target polynucleotide remaining secured to the substrate; following the removing, moving the substrate to which the target polynucleotide is secured to the sequencing zone; and detecting a second series of nucleotide incorporations complementary to at least a portion of the target polynucleotide, the second series of nucleotide incorporations forming a second complementary polynucleotide.

In a sucking operation, predetermined amount of a sample is sucked by using a needle from a sample container in which the sample to be analyzed is contained. A sensor circuit, which is electrically conducted to the needle, outputs different levels of signals when a tip of the needle is in contact with liquid and when the tip of the needle is not in contact with liquid. A liquid-contacting detector detects whether the tip of the needle is in air or in liquid by comparing a sensor signal value obtained from a signal output from the sensor circuit during the sucking operation with a preset threshold value. An empty container determiner determines that the sample container is empty when the liquid-contacting determiner detects a change during the sucking operation that the tip of the needle is changed from being in liquid to being in air.
