摘要： An analysis system for analysing the constituents of a sample of material is provided. A reference supply conduit supplies a source of a first gas. A carrier supply conduit supplies a source of the first or a second gas. First and second reactors are included. A first auto-sampler provides one or more samples of material, the first auto-sampler having an inlet for receiving gas and an outlet for providing the received gas and a sample to the first reactor. A second auto-sampler provides one or more samples of material, the second auto-sampler having an inlet for receiving gas and an outlet for providing the received gas and a sample to the second reactor. A thermal conductivity detector has first and second channels for identifying the relative conductivity of the gases in each channel. A valve system controls the flow of gas from the supply conduits to the auto-samplers.

摘要： With a water, particulate and fibre mixture, a method of quantifying fibre content may include providing a sample of the mixture, filtering the sample to produce a particulate and fibre mixture, burning the particulate and fibre mixture to produce a fibre sample, and dissolving the fibre sample to produce a fibre solution. The fibre solution may be analyzed to determine an elemental content of the fibre solution. The elemental content may be compared to a known elemental content to estimate the fibre content.

摘要： A first-half combustion period, for example, is estimated/evaluated, with a required accuracy, more simply than the conventional art, while reducing man-hours to produce a heat generation rate waveform of an internal combustion engine. Within a combustion period of an air-fuel mixture, a period from an ignition time FA to a heat generation rate maximum time dQpeakA where the heat generation rate is maximum is defined as the first-half combustion period a that is one of characteristic values of the heat generation rate waveform. The first-half combustion period a is estimated based on an in-cylinder volume at the heat generation rate maximum time, and furthermore by being corrected using an exponential function of the engine rotation speed with a value depending on a tumble ratio as exponent. Thus, the heat generation rate waveform is produced using the estimated first-half combustion period a.

摘要： An automatic cleaning assembly for an analytical furnace is detachable from the filter chamber above the combustion tube. The cleaning assembly includes a rotating brush which is lowered through the filter chamber and into the combustion tube while a vacuum is drawn through the lower seal of the combustion tube. This results in a higher vacuum pressure differential and improved flow rate for removing dust from the filter of the furnace and the combustion tube.

摘要： An analyzer with a combustion furnace includes a flow path of byproducts of combustion coupled to a bidirectional ballast chamber by valves which are sequentially actuated for alternately filling and exhausting byproducts of combustion from opposite sides of the chamber during combustion. Alternately, a plurality of low volume ballast chambers are employed. A method of determining the concentration of elements in a sample includes the steps of combusting a sample; and alternately collecting and exhausting the byproduct gases of combustion in opposite sides of a bidirectional ballast. The bidirectional ballast chamber has an outer wall defining a chamber with sealed enclosures at opposite ends of the wall, a movable piston positioned within the chamber, and gas ports associated with the chamber on opposite sides of the piston.

摘要： In this system, the carbon component of atmospheric particulate matter (PM2.5) is measured by: heating a sample in a first oven under such conditions as to fractionate the carbon component into carbon fractions; completely converting each carbon fraction into carbon dioxide gas in a second oven; and then measuring the amount of carbon dioxide gas in the carbon fraction precisely. In the system, the problem that a TCD detector cannot measure a low-concentration fraction is solved by using a combustion gas in a non-diluted state, though a combustion gas diluted 150-fold is used in a conventional elemental analyzer. Thus, the present invention develops an international standard instrument in which one standard sample is used and which enables simple standardized measuring acceptable to The International System of Units (SI).
