    Abstract: The present invention provides a soot-suppression flame-separation combustion device for combustion calorimetry and in-situ free radicals monitoring. The combustion device is mainly composed of a premixed combustion gas guide tube, an inner flame generating seat, an oxidation flame separation guide, and a sample combustion chamber; the inner flame generating seat is arranged in the premixed combustion gas guide tube, the oxidation flame separation guide is arranged on the premixed combustion gas guide outlet end of the premixed combustion gas guide tube, the sample combustion chamber is a cavity arranged inside the oxidation flame separation guide, and the oxidation flame separation guide is evenly arranged with at least 4 oxidation flame separation guide paths in a manner of surrounding the sample combustion chamber. The combustion device utilizes the special structure of the oxidation flame separation guide to suppress the generation of smoke and limit the smoke particles to a specific combustion area, thereby reducing the interference of sample combustion smoke on the spectral diagnosis method and improving the applicability of spectral diagnosis in sample combustion monitoring.

    Abstract: An in-vitro diagnostic (IVD) analyzer 200 comprising an optical detection unit 217 comprising a cuvette 214 for the optical measurement of a biological sample 2, 2' is herein disclosed. The IVD analyzer 200 further comprises a piezo actuator 218 arranged on one side of the cuvette 214 configured to transmit ultrasonic waves 254, 254' through the cuvette 214, a piezo receiver 218' arranged on the opposite side of the cuvette 214 configured to receive ultrasonic waves 255, 255', 255" transmitted through the cuvette 214, and a controller 250 configured to operate according to a lysis operating mode L and according to an air-detection operating mode AD. According to the lysis operating mode L the piezo actuator 218 is configured to transmit ultrasonic waves 254' through the cuvette 214 for disrupting cellular particles contained in the biological sample 2. According to the air-detection operating mode AD the piezo actuator 218 is configured to transmit ultrasonic waves 254 through the cuvette 214 and the controller 250 is configured to correlate changes in amplitude and/or shifts of phase of the ultrasonic waves 255, 255', 255" received by the piezo receiver 218' relative to reference values with an eventual presence and quantity of air 3 in the cuvette 214, in order to determine if the optical measurement of the biological sample 2, 2' is affected by the presence of air 3. A respective automated method of operating the in-vitro diagnostic analyzer 200 in order to determine if the optical measurement of the biological sample 2, 2' is affected by the presence of air is also disclosed.
