CCD: Charge Coupled Element. Can be called CCD image sensor, also called image controller.
Sample block: The metal block to be tested. The sample block with authority is called the standard sample.
Rowland circle optical system: Rowland circle scribes a series of parallel gratings on a concave spherical mirror surface. It has a spectroscopic ability and a focusing ability, and a spectrometer design structure.
Spark: The electrode discharge transitions, the spectrometer has high voltage and emits white light. The role is to excite the matrix effect: the matrix effect is the effect of coexisting elements on the measured element. Working principle: the sample is excited into an atomic vapor by an arc or spark discharge, and the atom or ion in the steam is excited to generate an emission spectrum. The spectroscopic chamber is dispersed into various spectral bands. According to the emission wavelength range of each element, the optimal spectral line of each element is measured by the photocell. The intensity of the spectral line of each element is proportional to the content of the element in the sample. The content can be measured and displayed directly as a percentage concentration.
Grating: An optical device that functions to split light. Refracting the spectrum to excite the system: use high-energy pre-ignition low-pressure spark excitation light to atomize the sample, and make the atomic emission spectrum optical system: process the optical signal, use gratings, etc. to split the light.
Measurement and control system: Measure the intensity of the characteristic spectral line representing each element, and by various means, convert the light intensity signal of the spectral line into a digital electrical signal that can be recognized by a computer. Control the normal operation of the entire instrument
Software processing system: The light of each channel received by the computer is calculated to obtain a stable and accurate sample content.
