An excreta sample capture device includes a primary influent pipe that receives influent from a toilet(s) and includes an upstream end and a downstream end. The excreta sample capture device also includes a first valve positioned at the downstream end of the primary influent pipe, and a second valve positioned between the upstream end and the downstream end of the primary influent pipe. In some cases, an excreta sample capture device further includes spray jet positioned above the second valve and a sample extraction vessel located downstream from the second valve. A method of using an excreta sample capture device includes receiving influent in the primary influent pipe, initiating a closing of the first valve, opening the second valve, and capturing a sample of the excreta.

An elemental analysis device includes a heating furnace in which a test sample that is placed in a crucible is heated so that a sample gas is generated from the test sample, an inflow path through which a carrier gas is introduced into the heating furnace, an outflow path through which a mixture gas made up of the carrier gas and the sample gas is led out from the heating furnace, a dust filter that is provided on the outflow path, an analysis mechanism that is provided on the outflow path on a downstream side from the dust filter, and that detects one or a plurality of predetermined components contained in the mixture gas, and a cleaning gas supply mechanism that supplies cleaning gas to the dust filter in an opposite direction from a direction in which the mixture gas is flowing.

Systems for monitoring metabolites may include a sample collection system and a urinalysis system of or for a toilet. The sample collection system may be automated to collect sample urine from a toilet or toilet area, transport the sample to the urinalysis system, and/or the sample urine for analysis at a later time or after analysis by the urinalysis system. The urinalysis system may be automated by proactively providing test material on which a subject may provide a urine sample. Once the urine sample has been provided the urinalysis system may provide the test material to an analyzer for analysis. Results of the analysis of the test material and sample urine may be provided to a mobile device of the subject and/or a remote server. The urinalysis system may provide a urine sample to a mass spectrometry unit for analysis.

Systems and methods of the present disclosure generally relate to reporting carbon and hydrogen isotopic ratios during a wellbore operation. A method for detecting isotopic ratios during the wellbore operation, comprises receiving a fluid sample from a wellbore during the wellbore operation; passing the fluid sample to an analytical instrument operable to determine isotopic ratios in the fluid sample; outputting data comprising isotopic ratios for at least carbon and hydrogen; assigning a depth to the data; and transmitting the data based on isotopic ratios encountered during the wellbore operation.

The system can also include at least one sample container and at least one unmanned aerial vehicle configured to transport the at least one sample container. The system can also include at least one valve that can be configured to open and discharge a sample of the lubricating fluid from the at least one fluid path into the at least one sample container. At least one unmanned aerial vehicle station can be configured to receive the at least one unmanned aerial vehicle. At least one retention and loading mechanism can be configured to move the at least one sample container.

The invention relates to a sample collection system for collecting sub-samples from a material stream, the system including a valve arrangement and a static cone splitter, and wherein the valve arrangement is arranged to enable operation of the static cone splitter to collect a non-biased sample of the material stream fed to the static cone splitter under first and second operational conditions, the first operational condition requiring the material stream to be at substantially atmospheric pressure and flowing at a minimum functional flow rate, and the second operational condition requiring the material stream to be pressurised above atmospheric pressure and at a flow rate higher than the minimum functional flow rate. The invention also relates to a static cone splitter for use with the system, together with a cone member for use with the static cone splitter.
