MEASUREMENT + INSTRUMENTATION

SPECTRO Analytical Instruments has published a re port detailing a new method for the elemental analysis of black mass from recycled lithium-ion batteries. This method uses the SPECTRO ARCOS MultiView ICP-OES with dual side-on plasma observation (DSOI) mode, enhancing sensitivity and accuracy in determining the composition of valuable elements like lithium, manga nese, cobalt, and nickel. The SPECTRO ARCOS system features CMOS detec tors (complementary metal-oxide-semiconductor tech nology used in imaging sensors) and a high resolution Paschen-Runge spectrometer mount with Optimised Rowland Circle Alignment (ORCA) technique, ensuring high sensitivity and minimal interference for accurate measurements. It provides enhanced sensitivity with the dual side-on plasma observation mode which offers up to twice the sensitivity of traditional single radial plasma observation, yet maintains the benefits of the radial method, making it efficient for analysing major as well as trace elements in battery black mass. The report compares two sample preparation meth ods: peroxide fusion and aqua regia extraction. Both methods showed excellent recoveries for major ele actions in its event memory, capturing all successful and unsuccessful attempts. Firmware integrity checks ensure the software update package is encrypted and signed, preventing unauthorised software from being loaded into the VEGAPULS 6X. Additionally, the instrument allows data backup for recovery through the DTM, with the option to save parameters using HART-enabled control systems. Handling a worst-case scenario When defending against a cyberattack, time is of the essence. Companies need to be prepared and this includes developing a clearly defined emergency plan to ensure that time is not wasted in case of an attack. It is also essential to plan how to rebuild a secure system in case significant damage is done. The PSIRT (Product Security Incident Response Team) at VEGA is always ready to help. This team of experts continuously searches for vulnerabilities in measurement systems, assists with updates and patches, addresses customer inquiries, and will take immediate action in critical situations, such as when a user discovers a vulnerability. VEGA also collaborates closely with CERT@ VDE, an IT security platform for industrial companies, to report and investigate vulnerabilities. VEGA level sensors have been used for monitoring in dustrial processes for many years. The VEGAPULS 6X sen sor is designed to be easy to set up, whatever the applica tion area, technology, or sensor version. The company also focuses on simplifying aspects related to cybersecurity, Elemental analysis in lithium-ion battery recycling

acknowledging that ensuring cybersecurity is an ongoing, dynamic process that requires continuous attention. VEGA works with plant operators to support security systems on the shop floor and encourages operators to implement the security measures outlined in its guidelines. The guidelines also offer suggestions for enhancing the security of produc tion systems. □
