Abstract
Apparatus, systems, and methods may operate to discharge a plurality of spike fluids into a fluid flowing in a flow channel, transmit energy to the fluid using an energy source coupled to the flow channel, receive the energy modified by the fluid as photometric energy, convert the photometric energy to at least one photometric signal, compare the at least one photometric signal with a reference signal to determine at least one photometric property of the fluid, and determine at least one component of the fluid using the at least one photometric property supplied to a generalized standard addition method (GSAM). Additional apparatus, systems, and methods, including the use of multivariate curve resolution (MCR) to refine GSAM results, are disclosed.
Claims26
An apparatus, comprising:
- a flow channel to contain a flow of fluid;
- a plurality of fluid injectors to discharge a corresponding plurality of spike fluids into the flow channel;
- at least one energy source coupled to the flow channel to direct energy into the fluid;
- at least one sensor coupled to the flow channel downstream from the plurality of fluid injectors, the at least one sensor to receive the energy modified by the fluid as photometric energy and to provide a signal indicating a property of the photometric energy;
- and
- a processor to acquire the signal and to determine a material or chemical property of the fluid using a generalized standard addition method.
