摘要： A system includes an analysis system at a first location and one or more remote sampling systems at a second location remote from the first location. A sampling system can be configured to receive a remote liquid sample. The system also includes a sample transfer line configured to transport gas from the second location to the first location. The sample transfer line is configured to selectively couple with a remote sampling system for supplying a continuous liquid sample segment to the sample transfer line. The system can further include a sample receiving line at the first location. The sample receiving line is configured to selectively couple with the sample transfer line and the analysis system to receive the continuous liquid sample segment and supply the sample to an analysis device.

摘要： A device is described for collecting samples of microorganisms in the air, such as bacteria, fungi, viruses, including SARS-CoV-2; intuitive to use, portable, and does not require specific technical knowledge to handle. The device works through an air flow sucked in by a centrifugal fan, where a filter retains the microorganisms for later use in diagnostic laboratories.

摘要： A method of reducing noise in an output signal of a differential refractive index detection part (RI detection part) of a dual-flow type with an analysis device having the RI detection part includes sending a sample liquid to a sample cell with a sample pump, sending a reference liquid to a reference cell with a reference pump, and detecting a change in direction of travel of light sequentially transmitted through the two cells with a light detector. Before starting RI measurement, a phase difference between the sample pump and the reference pump is adjusted so that a noise that occurs in an output signal of the light detector by propagation of pulsation from the sample pump within the sample cell and a noise that occurs in the output signal of the light detector by propagation of pulsation from the reference pump within the reference cell cancel each other.
