Hubei Fertilizer released 5 achievements in chemical analysis. Author/Source: Sinochem News Network. Date: December 16, 2020. Clicks: 70. On December 7, the Innovation Studio for Chemical Analysis led by Yang Jiangping from Sinopec Hubei Fertilizer Company announced 5 significant achievements. Through practical application, these achievements have eliminated production bottlenecks, playing a vital role in improving the accuracy of analytical data, guiding process optimization, and ensuring the optimal operation of equipment. Among them, \"Analyzing metal elements in liquid samples using X-ray fluorescence spectrometry\" takes only 3 minutes to determine all metal ions present in a liquid sample. It is suitable for monitoring heavy metal components in samples such as wastewater and waste residues, and it offers a significantly higher efficiency compared to the traditional atomic absorption method. “Gas chromatography for the determination of argon content in oxygen in products has high sensitivity, enabling the detection of argon at a concentration of 50 ppm in oxygen ； It features high analytical precision; six parallel measurements of the same sample yield a relative standard deviation of less than 3%. This enables monitoring of the argon content in the oxygen of products, thereby assisting in optimizing production processes. “\"Determination of ammonia nitrogen in wastewater with high chroma by gas-phase molecular spectroscopy\" addresses the issue that the Nessler’s reagent colorimetric method is disrupted by the high color intensity of wastewater, preventing accurate measurement of ammonia nitrogen levels; it provides guidance for optimizing wastewater treatment processes. ““The application of a sewage COD backwash device” involves installing a backwash device in the regulating tank to clean the sampling pipelines on a regular basis, which improves the accuracy of COD measurements to 98%, reduces the frequency of replacing the PVC sampling pipes, and lowers the workload for employees. “The laser method for determining the fineness of thermal coal powder is more commonly used than the vibrating screen method; it offers advantages such as higher precision in measuring coal powder, faster processing speed, a safer and more environmentally friendly analysis process, as well as cost savings in terms of labor and resources.
