In the realm of industrial chemistry, the accurate analysis of chemical substances is crucial for ensuring safety, quality, and efficiency across various applications. One such critical analysis involves the detection of Total Organic Carbon (TOC) in industrial hydrogen peroxide, a versatile chemical with a wide array of uses. In this blog post, Metash, a professional analytical laboratory instrument manufacturing company, will share the advantages of TOC Total Organic Carbon Analyzer for industrial hydrogen peroxide detection.
Importance of Hydrogen Peroxide
Industrial hydrogen peroxide (H2O2) is a multifunctional chemical with a broad spectrum of applications. Its potent oxidizing properties make it an essential component in numerous industries. From sterilization and disinfection in medical and public health settings to bleaching and cleaning in the textile and paper industries, hydrogen peroxide plays a vital role. Additionally, it serves as a key raw material in chemical synthesis and is instrumental in environmental protection, particularly in wastewater treatment and pollution remediation. The expanding industrial scale and increasing environmental regulations have further amplified its significance in emerging fields such as food manufacturing, aerospace, and metallurgy.
TOC Total Organic Carbon Analyzer for Detecting Hydrogen Peroxide
Given the critical applications of hydrogen peroxide, ensuring its purity and safety is of utmost importance. TOC analysis is a fundamental method to assess the quality of hydrogen peroxide. TOC refers to the total amount of organic carbon present in a sample, which can indicate the presence of impurities that might affect the performance and safety of the chemical. Accurate TOC measurements are essential for maintaining the efficacy of hydrogen peroxide in various industrial processes and for complying with regulatory standards.
TOC 5000 RD Analyzer
TOC 5000 RD analyzer is a state-of-the-art instrument designed for precise TOC analysis. This analyzer is equipped with advanced features that ensure reliable and efficient testing. It operates with a carrier gas flow of 180.0 ml/min and a pressure of 0.200 Mpa, utilizing platinum as a catalyst and employing oxygen with a purity of ≥99.995% as the carrier gas. The combustion tube temperature is maintained at 680℃, and the detection is carried out using a non-dispersive infrared detector (NDIR).
Experimental Methods
The TOC 5000 RD analyzer employs two primary methods for TOC analysis: the direct method and the difference method. Both methods involve diluting a 5ml sample of hydrogen peroxide to 100ml with pure water and utilizing the NPOC standard curve and the TOC method (TOC = TC – IC) to measure the organic carbon content. The analyzer also conducts spike recovery experiments to validate the accuracy of the measurements.
Standard Curves and Results
The accuracy of the TOC analysis relies heavily on the calibration of the analyzer using standard curves. The NPOC standard curve is prepared using potassium hydrogen phthalate, yielding a linear correlation coefficient (R2) of 1. The IC standard curve, prepared with anhydrous sodium carbonate and calcium bicarbonate, exhibits an R2 value of 0.9999. The TC standard curve, created by mixing organic and inorganic carbon standard solutions, also demonstrates an R2 value of 1.
The results of the TOC analysis using both the direct and difference methods are consistent and reliable. Each sample is tested three times to ensure reproducibility. The spectra of the samples tested using both methods show clear and distinct peaks, indicating accurate detection of TOC levels. The spike recovery experiments further confirm the reliability of the methods, with recovery rates within acceptable limits.
Conclusion
The TOC 5000 RD analyzer has proven to be an effective tool for detecting TOC in industrial hydrogen peroxide. Its advanced technology and precise calibration ensure accurate and reproducible results. The direct and difference methods both offer reliable means of measuring TOC levels, providing industries with a robust solution for maintaining the quality and safety of hydrogen peroxide.
