Device for pretreatment of sample and analyzer equipped therewith, and method for pretreatment of sample
A sample is dissolved in a reagent 4 containing an organic solvent in a conversion vessel 11. A gas is supplied from a first gas supply part into the conversion vessel 11 via a reagent introduction tube 17, and thus the interior of the conversion vessel 11 is pressurized. A gas is supplied from a second gas supply part into the reagent 4 in the conversion vessel 11 via a reagent discharge tube 18, and thus gas bubbles 41 are formed in the reagent 4.
Systems and methods for high throughput foam analysis
A system for high throughput foam analysis includes a foam generation system, an illumination source, a detection system and an analysis system. A foam generation system includes a first plurality of foaming units, each foaming unit including a foaming chamber and a gas induction mechanism. The illumination source provides an illumination to the foaming chamber of each foaming unit. The detection system includes a first camera configured to temporally record the foaming process in each foaming unit, thereby producing a first plurality of frames. The analysis system includes: at least one processor, and a memory including instructions for (i) obtaining a first respective frame in the first plurality of frames; (ii) segmenting the first respective frame into a first plurality of segmented images, and (iii) extracting, from each segmented image, one or more characteristics of the foam, thereby facilitating high throughput foam analysis of the first plurality of solutions.
System and Method of Producing Foamed Cement in a Laboratory Environment
Systems and methods related to preparing foamed cement for laboratory analysis are provided. A prepared cement slurry is placed in a cement reservoir cell configured to pressurize the cement slurry contained within the cement reservoir cell to a capture pressure. After pressurization, the cement slurry and a compressed gas are introduced into a foam generator. Foamed cement generated in the foam generator is introduced from the tee into a foam capture cell where it can cure prior to analysis.
NON-DESTRUCTIVE SAMPLING SYSTEM AND METHOD FOR QUALITY ASSESSMENT OF BLOOD PRODUCTS, AND SAMPLING SYSTEMS THEREFOR
There is provided a method of sampling an aliquot of blood products from a main container containing the blood products to be sampled. The method includes providing a sample container that is rectangular-shaped and has a length-over−width (L/W) ratio of at least that of the main container, and fluidly connecting the a sample container to the main container, transferring the aliquot of the blood products from the main container to the sample container, and forming an air bubble in the sample container by introducing a volume of air into the sample container with the aliquot of the blood products. The volume of air forming the air bubble corresponds to at least about 5% of a volume of the aliquot of the blood products. A sampling bag and a sampling system are disclosed.
APPARATUS FOR PROVIDING OBJECT TO BE MEDICALLY EXAMINED BY BLOWING
An apparatus for providing an object to be medically examined by blowing is provided where air is blown into a container in which an object to be medically examined is stored, so as to make the uniform distribution state of the object to be medically examined from the inside of the container, thereby ensuring the sameness of the object to be medically examined, which is to be extracted from the container.
SYSTEMS AND METHODS OF DETERMINING ISOTOPIC COMPOSITION OF GASEOUS SAMPLES
A system for determining isotopic composition of a gaseous sample. The system includes at least one gas chromatograph for separating the gaseous sample into gaseous components. Furthermore, the system includes a combustion furnace operatively coupled with the at least one gas chromatograph for oxidizing the gaseous components. Moreover, the system includes a water separator operatively coupled with the combustion furnace. Furthermore, the system includes an isotope-ratio mass spectrometer operatively coupled with the water separator. Moreover, the isotope-ratio mass spectrometer comprises an ion source for generating ion beams associated with each of the oxidized gaseous components and a mass analyser for receiving the generated ion beams from the ion source, wherein the mass analyser is operable to determine isotopic concentrations associated with each of the ion beams. Furthermore, the isotope-ratio mass spectrometer is operable to use the determined isotopic concentrations to determine the isotopic composition of the gaseous sample.

METHODS TO ANALYZE HYDROCARBON SOLUTIONS
The present application describes a method to reduce noise and improve data quality when analyzing hydrocarbon compositions with a Quartz Crystal Microbalance (QCM). In some approaches, the methods described in this disclosure remove at least a portion of volatile components from the hydrocarbon composition to be tested with the QCM.
System and method for metering, dispensing, filtering, and mixing micro-volumes of fluids
Devices for micro-fluid mixing micro-fluids are presented, together with example methods for micro-mixing using example devices. An example device may include a micro-volume fluid chamber (VFC), a micro-volume mixing chamber (VMC), and a source of a target micro fluid. The VFC may include two slidably-mounted piston segments that divide the VFC into three sub-volumes, one of which initially contains a mixer micro-fluid. The source of the target micro fluid may be triggered to deliver the target micro-fluid into another of the sub-volumes via an inlet channel. A propellant may be triggered to drive axial motion of the piston segments, causing the sub-volumes to compress. Through this action, the mixer micro-fluid may be expelled via a first outlet channel into the VMC, and the target micro-fluid may be expelled via a second outlet channel into the VMC. As the piston segments move, they block and unblock the inlet and outlet channels.
BUBBLE-BASED ELECTROCHEMICAL METHODS FOR THE ENRICHMENT AND DETECTION OF SURFACTANTS IN AQUEOUS SOLUTIONS
Bubble-based systems and methods to detect surfactants, such as perfluorooctanesulfonate (PFOS) and perfluorooctanoic acid (PFOA) in aqueous solutions including water supplies are described. The systems and methods can utilize a surfactant preconcentration step to increase the sensitivity of the methods. Preconcentration can be based on aerosol formation and capture.
