Liquid testing system and method

A system for analyzing a sample directly in a container, the system comprising:

• one or more sample containers for storing a sample to be analyzed, the sample being obtained from a sample source;
• and
• one or more sample readers for directly analyzing the sample in the one or more sample containers to provide one or more measurements of the sample;
• wherein the one or more sample containers are in communication with one or more other containers via a central processing unit (CPU).

A method of analyzing a petroleum sample directly in a container, such that the sample is not exposed to an environment external to the container, comprising the steps of:

• (a) providing a container, the container comprising:
• a sample chamber capable of being fluidly connected to a sample source for flow-through sampling, and
• a measurement chamber, wherein the measurement chamber is capable of being fluidly connected to the sample chamber,
• the sample chamber comprising:
• an inlet valve and an outlet valve for flow-through sampling of the petroleum sample,
• a measurement valve for releasing the sample to the measurement chamber, and
• an inline filtering component disposed between the measurement valve and
• a point of connection of the sample chamber to the measurement chamber,
• the measurement chamber comprising:
• at least a first chamber fluidly connected to one or more sensors for measuring pressure and temperature, and
• a closure valve;
• (b) connecting the sample chamber to the sample source;
• (c) allowing the sample to flow from the sample source through the sample chamber via the inlet valve and the outlet valve, and thereafter closing the inlet valve and the outlet valve to obtain the sample to be analyzed in the sample chamber;
• (d) connecting the sample chamber to the measurement chamber;
• (e) moving the measurement valve to an open position to release the sample to the measurement chamber, wherein sample liquid is contained by the inline filtering component and wherein sample vapour enters and expands within the first chamber of the measurement chamber;
• and
• (f) measuring the pressure and temperature of the sample vapour in the measurement chamber;
• wherein the container can be fluidly connected to one or more additional containers configured to measure one or more additional properties of the sample, the method further comprising:
• connecting the container to one or more additional containers configures to measure one or more additional properties of the sample, and
• measuring one or more additional properties of the sample.
