Elemental composition of a pipe is determined by a fluorescence x-ray detector device. An outer housing of the device is inserted into the pipe via a flexible insertion member. A radioactive x-ray source is encompassed by a shield within the housing. A shutter selectively opens to enable radiation from the x-ray source to exit the shield and illuminate an inner wall of the pipe. An x-ray detector within the housing detects fluorescence x-rays emitted from the pipe upon illumination by the x-ray source. A controller then determines the presence of one or more elemental materials contained within the pipe based on the fluorescence x-rays.

A method for multi-parametric x-ray fluorescence imaging with maximized detection sensitivity and minimized radiation dose for a biological/living sample (10) containing a first marker substance comprises the steps of irradiation of the sample (10) with x-ray radiation (1), with x-ray fluorescence (2) of the first marker substance being excited, spatially resolved detection of the x-ray fluorescence (2) of the first marker substance, and determination of a distribution of the first marker substance in the sample (10) from the x-ray fluorescence (2) of the first marker substance, wherein the sample (10) contains at least one further marker substance which is excited to x-ray fluorescence (2) by the x-ray radiation (1), wherein fluorescence lines (3) of the first and the at least one further marker substances are different, at least one of the first and the at least one further marker substances is coupled with active ingredient molecules and/or ligand molecules provided for a specific interaction with the sample (10) or contained in cells, in order to be able to trace these, the detection comprises a spectrally resolved detection of the x-ray fluorescence (2) of the first and the at least one further marker substances, and additionally at least one distribution of the at least one further marker substance in the sample (10) is determined from the detected x-ray fluorescence (2) of the first and the at least one further marker substances. An imaging device (100) for multi-parametric x-ray fluorescence imaging and an optimized selection method for a marker substance kit for introducing marker substances into a sample (10) are also described.

Contemplated is a sensor system for use with a measuring device. The measuring device being of the type adapted to measure the volume of a desired solid component in a sample volume of a solid-liquid slurry obtained from either a carbon-in-pulp or carbon-in-leach process. The solid-liquid slurry comprises granular carbon particles, ore pulp, and water. The carbon-in-pulp or carbon-in-leach process includes at least one retention tank. The measurement device including: a receptacle for receiving the sample volume of the slurry; a screen provided in the receptacle for separating out the desired solid component from a remainder of the slurry. The solid component is retained in the receptacle to form a bed therein and the remainder is exhausted from the receptacle. The sensor system measures in either the retained solid component, or the exhausted remainder, or both one of: pH; dissolved oxygen; pulp density or carbon content.
