Absorption theory:
Absorption spectroscopy is widely used in various fields and can distinguish compounds from mixtures. Almost every element has an absorption peak of a specific wavelength in the electromagnetic spectrum. These unique spectral features allow scientists to know which elements and compounds are present in their samples. PX2+is an instrument for measuring the concentration of organic and inorganic compounds by determining the absorbance of light at specific wavelengths. PX2+is a photometer that utilizes Beer's law - attenuation when light passes through a substance - to monitor changes in concentration during analysis. PX2+sends radiation from the internal light source of the instrument to a flow cell, and returns the signal to the instrument through an optical interface coupler and fiber optic cable. PX2+uses filters to ensure a specific wavelength range of measurement light and reference light to match the analysis absorbance. The signal is linearized, and the generated analog or digital signal can be sent to PLC or DCS for process control. CST also offers single channel transmission, dual channel transmission, and ATR detectors, which can use optical interface couplers according to process requirements.
Fluorescence theory:
When a molecule absorbs light of one wavelength and re emits it at another wavelength, it produces fluorescence. The wavelength at which maximum absorption occurs is called the excitation wavelength, and the wavelength at which maximum emission occurs is called the emission wavelength. PX2+uses optical filters to ensure a specific excitation/emission wavelength range for fluorescence analysis. Fluorescence spectroscopy can be used to measure the concentration of compounds, as the fluorescence intensity is directly proportional to the concentration of fluorescent molecules. Only molecules that can excite fluorescence can be measured using this method. The sensitivity and specificity of fluorescence measurement are more accurate and precise than absorbance measurement methods. The front surface fluorescent probe is a key component for measurement using PX2+. The light source in PX2+provides excitation light to the probe tip through a fiber optic cable. The spherical mirror is located on the sensing surface of the detector and focuses the excitation light through the sapphire probe window. Then, the excitation light is absorbed by the analyte, resulting in emission light. This emitted light is transmitted back to the PX2+concentration detector through another optical fiber. Due to the design of surface probes, the front surface fluorescent probes are less susceptible to internal filtering effects and the influence of bubbles or suspended solids.
