How many terms do you know about the spectrum analyzer?

Release time: 2017-07-31 15:06:41 Click: 5508

CCD: Charge coupled element. It can be called CCD image sensor, also called image controller.
Sample block: The test metal block, the sample block with the authority is called the standard sample.
Rowland circle optical system: Rowland circle scribes a series of equally spaced parallel lines on the concave spherical mirror surface. It has a splitting and condensing ability, and a spectrometer design structure.
Spark: Electrode discharge transition occurs, the spectrometer has high voltage, and emits white light. The function is to stimulate the matrix effect: the matrix effect is the influence of the coexisting elements on the measured element. The working principle: the sample is excited into an atomic vapor by arc or spark discharge. The atoms or ions in the vapor are excited to produce an emission spectrum. The dispersion chamber is dispersed into various spectral bands. According to the emission wavelength range of each element, the best 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 calibration curve is prepared internally. The content can be determined and displayed directly as a percentage concentration.
Grating: optical device, the function is to split light. Refract the spectrum to excite the system: use high-energy pre-ignition low-pressure spark to excite the light, atomize the sample, and make the atomic emission spectrum Optical system: process the optical signal, use a grating, etc. to split the light.
Measurement and control system: measures the characteristic spectral line intensity representing each element, and converts the light intensity signal of the spectral line into a digital electrical signal that can be recognized by the computer through various means. Control the normal operation of the entire instrument

Software processing system: calculate the light received by the computer in each channel to obtain stable and accurate sample content.
