Applications
The industries such as petroleum , chemical , metallurgy, environmental protection , paper-making , municipal , biochemical medicine and water treatment.
Working principle
The photoionization detector provides ionization energy via a high-energy ultraviolet lamp.
When the volatile organic compounds (VOCs) with an ionization potential (IP) less than the energy of the ultraviolet lamp passes through the ionization cavity, the ultraviolet light source (UV) of the PID will break the compound into detectable positive and negative ions (that is , the ionization process) . The detector measures the ionized gas charge and converts it into a current signal , which is then amplified and converted into a concentration value . Upon the detection , the ions recombine into the original gas and vapor.AS-525

DPD Online Residual Chlorine/ Total Chlorine Water analyzer
The Bebur BC350Online Residual Chlorine/ Total Chlorine Water analyzer is acompact, well-structured and easy to operate water analysis instrument. The analyzer measures residual chlorine and total chloring in water using the DPD colorimetric method: Reagents are injected into the water sample by a reagent pump to complete the reaction,and the DPD Colorimetric method is then used to accurately determin the sample concentration. Users can select different reagents to achieve targeted measurement of residual chlorine or total chlorine. In addition, the instrument is equipped with a large-capacity data storage module,which can store test data for more than 10 years, helping users analyze long-term water quality variation trends.
