A humid air forming device, which cools an object to be measured to a predetermined temperature, and which sprays humid air having a predetermined temperature to the cooled object to be measured, thereby forming moisture particles on the surface of the object to be measured, and a measurement system including the same. The humid air forming device includes a cooling unit that cools the object to be measured to a first temperature or lower; and a humid air supply unit that forms humid air having a second temperature, which is higher than the first temperature, and spraying the humid air toward the surface of the cooled object to be measured, thereby forming moisture particles on the surface of the cooled object to be measured.

A method for the regulated humidification and temperature control of a gas mixture in an inner chamber of an incubator, which inner chamber is sealed off from the surroundings by a housing, includes conducting heat from at least one condensation surface inside the incubator, which at least one condensation surface is separate from the inner surfaces of the inner chamber, is conducted out of the incubator to the outside through a wall delimiting the inner chamber by a heat conductor. Outside the incubator, the heat conductor is connected to a cooling body which releases the heat to the relatively cold ambient air. The method allows dispensing with a cooling unit and at the same time avoid sources of contamination due to moisture condensing out.

A desorber for a trace detection system. The desorber includes an inlet configured to receive a sample, a heating element configured to generate a vapor from the sample, and an active cooling element configured to cool the desorber.

A droplet dispensing apparatus includes a crystal sensor, a resonance frequency measuring unit, and a controller. The controller is configured to obtain the resonance frequency of the crystal sensor before droplets are discharged from a liquid dropping device, control the liquid dropping device to discharge droplets on to the crystal sensor, and obtain the resonance frequency of the crystal sensor after droplets are discharged from the liquid dropping device. The controller estimates a volatilization amount for the droplets on the crystal sensor based on a temporal change trend in the resonance frequency of the crystal sensor and calculates the total weight of the droplets discharged from the liquid dropping device based on the difference in resonance frequency of the crystal sensor before and after the droplets are discharged and the estimated volatilization amount.

Methods for cell analysis are provided, comprising cell capturing, characterization, transport, and culture. In an exemplary method individual cells (and/or cellular units) are flowed into a microfluidic channel, the channel is partitioned into a plurality of contiguous segments, capturing at least one cell in at least one segment, A characteristic of one or more captured cells is determined and the cell(s) and combinations of cells are transported to specified cell holding chamber(s) based on the determined characteristic(s). Also provided are devices and systems for cell analysis.

The present invention is directed to a continuous fluid sample processing device for producing individually processed fluid samples and a method for producing individually processed fluid samples. Moreover, the invention also relates to the use of the device in corresponding methods, in particular in a method for continuously mixing, incubating and analyzing a fluid sample by flow cytometry.

A device for measuring superfine particles masses includes an exposure system with at least two measurement chambers having an identical geometry. Each measurement chamber has a deposition surface for the superfine particles which each have an aerosol feed line. The aerosol feed line has an outlet region to feed an aerosol onto the deposition surface, a means for generating a potential difference between the superfine particles in the aerosol and the deposition surface, and a grid arranged above the deposition surface. The outlet region has a widened outlet cross section having a constant distance from the deposition surface. At least one deposition surface is arranged on a piezoelectric crystal as a superfine balance. A first potential corresponding to a ground potential is present at each deposition surface. A second potential having a potential difference of at least 200 V in relation to the first potential is present at each grid.

With respect to a clean air device, in order to provide a device structure and an air cleaning unit inspecting method capable of supplying clean air through a filter and also capable of measuring the amount of dust in a workroom space in which blown air forms a laminar flow such that an increase in the amount of dust can be accurately detected, the clean air device comprises an air cleaning unit, a rectifying unit arranged downstream of the air cleaning unit configured to rectify air blown from the air cleaning unit and form a laminar flow, and a workroom arranged downstream of the rectifying unit, wherein at least one suction port is provided on a wall surface in a space formed between the air cleaning unit and the rectifying unit, configured to draw out the air in the space to an exterior.

A reaction device is provided with a reaction tube and an inert gas supply passage. The reaction tube may be composed of an alumina sintered body and configured to oxidize and reduce a sample gas therein. An inert gas is supplied into the reaction tube through the inert gas supply passage. With this, since it is possible to reduce the contamination that interferes with activation of the alumina sintered body, aging time can be shortened.

A sample preparation blister pack can include a plurality of reservoirs formed as blisters. The reservoirs can have an actuatable barrier layer and a seal barrier layer with contents of the reservoirs between the actuatable barrier layer and the seal barrier layer. The contents can be to facilitate isolating a biological component from a biological sample. The individual reservoirs can be adapted to release the contents through the seal barrier layer upon actuation of the actuatable barrier layer. The blister pack can have a width and a length and the reservoirs can be lined up along the length. In this example, a first reservoir contains an inert mechanical fluid and a second reservoir contains a reagent, a buffer, or a combination thereof.
