  • Patent number: 10871429
    Abstract: The purpose of the present invention is to provide an injection apparatus and an injection method for a liquid sample for standard gas production, wherein the injection apparatus for injecting a liquid sample present in a liquid state at room temperature into a standard gas container has an improved structure that minimizes the area in which the liquid sample directly contacts the injection apparatus so as to prevent the problem in which the liquid sample is adsorbed into the injection apparatus. Furthermore, another purpose of the present invention is to provide an injection apparatus and an injection method for a liquid sample for standard gas production, in which a step of volatilizing the remaining liquid sample by heating is eliminated during the injection of the liquid sample, thereby preventing the apparatus from being damaged by heating to thereby improve the durability of the apparatus.

    Abstract: Device for taking samples from the bottom boundary layer of a water body, consisting of compact bottom sediments, overlying water-saturated mud layer, and near-bottom water layer directly connected with the latter, belongs among oceanographic devices. Disturbance of the probes' structure is avoided by the construction of the device with several shorter tubes with their inlet holes being located at different heights, instead of one long sampling tube. There are distinctive tubes for taking samples from layers at different heights from the bottom. The sampling tube divided into sections is furnished with isolating valves that divide the interior of the tube into layers isolated from each other. Soft and regulated drop of the device is achieved using the inflatable contact belt. Using an upper inflatable balloon avoids the vertical stability of the device and raising it to the surface without cabling.

  • Patent number: 8336402
    Abstract: The present invention is directed to devices and methods in which one or more miniature synthetic jet actuators are integrated with a chemical fluidic sensor (ChemFET) to effect inhalation and exhalation of ambient gas samples and induce small scale mixing at the surface of the sensor. The fluidically integrated jet transports ambient gas or liquid into the jet/sensor assembly through integrated gas or liquid channels, impinges the sample gas or liquid on the sensing element, and finally ejects the sample gas or liquid back into the ambient gas or liquid. The response of the sensor in the presence of the active jet is compared to its response when the jet is inactive. The jet actuator directs entrained ambient gas or liquid toward the active surface of the sensor, and the impingement of sample gas or liquid onto the surface of the sensor results in faster response time. Other embodiments are also claimed and described.

  • Patent number: 8302495
    Abstract: In the method, for collecting and diluting a gaseous sample disposed at a temperature substantially higher than the normal temperature from a sample space (2), a flow of sample is collected into a sampling tube (3); the flow of sample is introduced from the sampling tube into a sample channel (8) formed by a gas permeable first jacket (7); dilution gas is introduced into a dilution gas space (10) formed by a second jacket (9) enclosing the first jacket and connected by its end to the sampling tube, and further from it, through the first jacket into the sample channel; and heat is conducted from the sample space (2) into the dilution gas space (10) for warming up the dilution gas that comes into contact with the sampling tube (3). According to the invention, in the method, a substantially laminar protection flow, which encloses the flow of sample being released from the sampling tube (3) into the sample channel (8) and is disposed longitudinally to the sample channel, is formed from the warmed up dilution gas.
