A carbon dioxide sensor has a conduit connecting to a source of breathing air and delivering a sample of breathing air into a test chamber. A radiation source applies radiation across the chamber. A sensor detects modification in the radiation as it passes through the air sample in the test chamber and communicates with electronics to identify a percentage of carbon dioxide in the sample. A rigid cover surrounds the radiation source, the test chamber, and the sensor. A spacesuit is also disclosed.

The device for monitoring the spatial and temporal dynamics of thrombin that includes a temperature-controlled sealed chamber with a transparent window and a light trap, said chamber being filled with a fluid medium and designed to be capable of accommodating a cuvette containing a test sample of blood plasma, and into which a coagulation activating insert is placed, the latter having a substance which initiates the coagulation process applied to the butt end thereof, at least one means of illumination of the sample designed to be capable of receiving the light scattering signal from the sample and at least one first means of irradiation designed to be capable of exciting the fluorescence signal of a special marker that forms in the sample during the cleavage of a fluorogenic substrate previously added to the sample by one of the proteolytic enzymes of the coagulation system, a means of optical photo/video registration of light scattering/irradiation from the sample, a means for adjustment of pressure in the temperature-controlled sealed chamber designed to be capable of maintaining a pressure inside the chamber exceeding the atmospheric one, at that the device includes at least one second means of irradiation of the sample designed to be capable of exciting a fluorescence signal of the said marker, at least one first means of irradiation that provides irradiation of the sample in a direction perpendicular to the cuvette plane, and at least one second means of irradiation that provides irradiation of the sample at an angle to the cuvette plane.

Methods and systems of performing an assay. A system for performing an assay includes an enclosure defining a temperature-controlled space. An imaging system, an actuator and a dispenser are disposed within the space. The actuator receives a well plate having wells. The actuator is to move the well plate relative to the imaging system to enable the imaging system to obtain image data of one of the wells. The dispenser includes a pump, an outlet and a reservoir holder to receive a reservoir containing a compound. The pump is to be fluidly coupled to the reservoir and an outlet. The pump is to pump the compound from the reservoir through the outlet into one of the wells. The system also includes a controller. The controller is to cause the dispenser to dispense the compound into the first one of the wells while the imaging system obtains the image data.

A portable testing device includes a hosing with an integrated touchscreen display and a receptacle in which a sample holder containing a biological sample and reagent mixture can be placed. The portable testing device further includes an optical assembly positioned in the housing, an electronic assembly that is configured to receive data from the optical assembly and transmit it for display upon the touchscreen display, and a power supply in the housing to power the portable testing device. The optical assembly includes an excitation filter that extends across the entire optical assembly and an emission filter that extends across the entire optical assembly.

A measurement device includes: a container into which sample gas is to be injected; a liquefaction mechanism configured to liquefy the sample gas in the container; a near-infrared probe extending from inside to outside the container; and a near-infrared measuring instrument configured to measure an absorbance spectrum of the sample gas in a state of being liquefied by the liquefaction mechanism, via the near-infrared probe.

A method for correcting a wavelength and a tuning range of a laser spectrometer in which the light from a wavelength-tunable laser diode, after being radiating through a gas, is detected and evaluated, wherein the laser diode is periodically driven with a current ramp, such that a time-resolved absorption spectrum of the gas is obtained upon the detection of the light, where in order to correct the wavelength and the tuning range of the laser spectrometer, a first step involves readjusting the central wavelength of the laser diode via the temperature thereof and based on the position of one of two different selected absorption lines in the detected absorption spectrum, and a second step involves correcting the tuning range of the laser diode via the gradient of the current ramp such that the spacing of the two absorption lines in the detected absorption spectrum remains constant.

An improved electronically controlled portable testing system provides one or more self-contained, automated testing skids configured to perform required tests on the exhaust output of a stationary engine. The testing skids are configured for easy transportation on a medium duty truck and in a preferred testing process, are deployed to the engine site (and reloaded on the truck after testing is complete) using a lift attached to the truck. Using these systems and methods, a single technician can concurrently test multiple exhaust stacks on engines separated by any distance, from 100 feet to miles apart. The testing skids provide the technician with wireless remote test control and monitoring. The disclosed systems and methods increase the efficiency, accuracy and repeatability of tests.
