Abstract: A method of and system for detecting the concentration of a target element in a brine wherein the brine is sampled into a container and an aerosol generator is used to generate an aerosol stream of the sampled brine in the container. The aerosol stream may be directed to a collection system. A handheld LIB S device directs a laser beam to the aerosol stream at a location between the aerosol generator and the collection system to generate a plasma. The plasma is analyzed to detect intensity data for a reference element based on the generated plasma and to detect the intensity data of a target element based on the generated plasma. The concentration of the target element in the brine is calculated based on the reference element intensity data and the target element intensity data.

Abstract: A spectroscopy instrument and method including a source of electromagnetic radiation, a controllable power source for energizing the source of electromagnetic radiation to direct the electromagnetic radiation to a sample for analysis by one or more spectrometers, and a temperature sensor. There is a controller, memory, and controller instrument warm-up instructions, stored in the memory. The instrument warm-up instructions are configured to read an output of the temperature sensor. If the temperature sensor output indicates an instrument temperature lower than a first setpoint, the power source is controlled to energize the source of electromagnetic radiation to heat the instrument. If the temperature sensor output indicates the instrument temperature is equal to or higher than a second setpoint, the power source is controlled to de-energize the source of electromagnetic radiation.
