APPARATUSES AND METHODS FOR SAMPLE-SPECIFIC SELF-CONFIGURATION
Embodiments in accordance with the present disclosure are directed to configuring an analyzer apparatus for processing a particular sample-processing cartridge. The analyzer apparatus includes a portable container and sample-specific configuration circuitry. The portable container supports and integrates a sample-processing cartridge and the sample-specific configuration circuitry. The sample-specific configuration circuitry identifies configuration information specific to the sample-processing cartridge and configures the analyzer apparatus for a series of state configurations. The configuration can be performed by selecting which of a plurality of biological-sample stimulators to interact with the biological sample, identifying positions in the portable container for each of the selected ones of the plurality of biological-sample stimulators at different times, and while the selected ones of the plurality of biological-sample stimulators are in the identified positions, causing the interactions between the selected ones of the plurality of biological-sample stimulators and the biological sample.
Method for diluting a sample liquid and dilution unit for a subsequent analysis
The present disclosure relates to a method for diluting a sample liquid taken from a sampling point for the subsequent determination of a parameter which depends on a concentration of at least one analyte in the sample liquid, including: supplying a first quantity of the sample liquid to a mixing device via a first sample liquid line; supplying a second quantity of the sample liquid to a separator via a second sample liquid line; separating the analyte from the second quantity of the sample liquid supplied to the separator by means of the separator to obtain a dilution liquid that no longer contains the analyte, and mixing at least one portion of the first quantity of the sample liquid supplied to the mixing device via the first sample liquid line with at least one portion of the dilution liquid by means of the mixing device.
SYSTEMS AND METHODS FOR CONTINUOUS FLOW DIGITAL DROPLET POLYMERASE CHAIN REACTION BIOANALYSIS
Systems and methods for continuous flow polymerase chain reaction (PCR) are provided. The system comprises an injector, a mixer, a coalescer, a droplet generator, a detector, a digital PCR system, and a controller. The injector takes in a sample, partitions the sample into sample aliquots with the help of an immiscible oil phase, dispenses waste, and sends the sample aliquot to the mixer. The mixer mixes the sample aliquot with a PCR master mix and diluting water, dispenses waste, and sends the sample mixture (separated by an immiscible oil) to the coalescer. The coalescer coalesces the sample mixture with primers dispensed from a cassette, dispenses waste, and sends the reaction mixture (separated by an immiscible oil) to the droplet generator. The droplet generator converts the sample mixture into an emulsion where aqueous droplets of the reaction mixture are maintained inside of an immiscible oil phase and dispenses droplets to the digital PCR system. The digital PCR system amplifies target DNAs in the droplets. The detector detects target DNAs in the droplets. The controller controls the system to run automatically and continuously.

Monitoring system and detecting device
A purpose is to provide a monitoring system to monitor whether there is a substance to be monitored in the air, and a detecting device used in the monitoring system. The monitoring system includes a detecting device, an analyzing device, and an abnormality notification system. The detecting device determines whether the air is in an abnormal state on the basis of an output signal from an abnormality detection sensor, pours liquid to be inspected, into which the air is sucked and liquefied, into a previously-installed reagent container when determining the abnormal state, generates mixed liquid in which a reactant in the reagent container and the poured liquid to be inspected are mixed, and drops the generated mixed liquid to an electrode of the analyzing device. The analyzing device determines existence/non-existence of a substance to be monitored on the basis of the mixed liquid dropped to the electrode, and gives a predetermined notification to the abnormality notification system when determining that there is the substance to be monitored. The abnormality notification system gives a predetermined notification when receiving the notification from the analyzing device.
