An analysis apparatus comprising: an injection nozzle; a specimen container; a test sample tank; a collecting unit configured to collect a specimen from the specimen container and transfer the collected specimen to the test sample tank where the specimen is processed into a test sample; a first influx channel and a second influx channel, each configured to receive a flow of the test sample; a dispensing unit, distanced from the collecting unit, configured to inject the test sample from the test sample tank into the influx channels; a first channel configured to fluidly connect the injection nozzle to a first valve; a second channel configured to fluidly connect the first valve to a second valve, wherein the second valve is fluidly connected to the dispensing unit; processing units ( 34, 35) configured to process the test sample in the influx channels; and a detecting unit configured to detect characteristic components contained in the test sample in the influx channels; and a controller comprising a first cleaning unit controller configured to control the first and second valves (51, 52) to lean the collecting unit and the test sample tank and a second cleaning unit controller configured to control the first and second valves (51, 52) to clean the dispensing unit and the influx channels, wherein the second cleaning unit controller is configured to clean the dispensing unit and the influx channels such that the time taken to clean the dispensing unit and the influx channels at least partially overlaps in time with the time during which the collecting unit transfers the specimen into the test sample tank and the time during which the specimen is processed into a test sample in the test sample tank. an injection nozzle; a specimen container; a test sample tank; a collecting unit configured to collect a specimen from the specimen container and transfer the collected specimen to the test sample tank where the specimen is processed into a test sample; a first influx channel and a second influx channel, each configured to receive a flow of the test sample; a dispensing unit, distanced from the collecting unit, configured to inject the test sample from the test sample tank into the influx channels; a first channel configured to fluidly connect the injection nozzle to a first valve; a second channel configured to fluidly connect the first valve to a second valve, wherein the second valve is fluidly connected to the dispensing unit; processing units ( 34, 35) configured to process the test sample in the influx channels; and a detecting unit configured to detect characteristic components contained in the test sample in the influx channels; and a controller comprising a first cleaning unit controller configured to control the first and second valves (51, 52) to lean the collecting unit and the test sample tank and a second cleaning unit controller configured to control the first and second valves (51, 52) to clean the dispensing unit and the influx channels, wherein the second cleaning unit controller is configured to clean the dispensing unit and the influx channels such that the time taken to clean the dispensing unit and the influx channels at least partially overlaps in time with the time during which the collecting unit transfers the specimen into the test sample tank and the time during which the specimen is processed into a test sample in the test sample tank.
