In the real world, chemical and analytical instruments are used for testing and measurement to benefit mankind. For example, this includes applications such as ambient air and water quality monitoring, material and product analysis to improve product quality, oil and geophysical exploration, and deepening scientific exploration. Chemical analysis involves the use of light detection and charged ion beams, redox reactions, and other technologies. The analysis methods for implementing these technologies are selected according to the sample type and measurement characteristics, including spectroscopy, spectrography and electrochemical methods. Accurate high confidence detection, recognition and characterization cannot be separated from accurate detection functions and electronic equipment. ADI's outstanding signal link, sensor, power supply and processor solutions ensure that the detection limit (LOD) and accuracy are not limited by electronic product design.
