从实验室到无人区：第三代便携式锂钾分析仪，走出“为国找矿”的实战之路

Core Viewpoint - The portable lithium-potassium analyzer developed by the National Geological Experiment and Testing Center has evolved into its third generation, marking a significant transition from productization to industrialization, addressing the critical need for lithium and potassium resource exploration in China [1][10][20]. Group 1: Product Development and Features - The third-generation portable lithium-potassium analyzer (Li-K Analyzer III) has been showcased at BCEIA2025, attracting significant attention from users [2][4]. - The analyzer has undergone over ten years of development, with the first generation validating the feasibility of its detection technology, and the second generation optimizing stability for field conditions [10][11]. - Key technological breakthroughs in the third generation include improved sensitivity, reduced detection limits, and enhanced analysis efficiency, making it suitable for high-altitude and remote exploration [14][18]. Group 2: Strategic Importance of Lithium and Potassium - Lithium and potassium are critical strategic minerals for China, with lithium being essential for the new energy industry and potassium being vital for agricultural productivity [9][10]. - The domestic self-sufficiency rate for potassium salts is only about 50%, indicating a heavy reliance on imports, which poses risks to food security [9]. Group 3: Applications and Future Prospects - The portable analyzer is expected to play a crucial role in the new round of mineral exploration strategies, with its technology already included in national standards [15][20]. - Beyond geological exploration, the analyzer has potential applications in environmental monitoring and healthcare, such as detecting lithium levels in water and blood [23]. - The commercialization of the analyzer is anticipated by 2026, with confidence in its market performance and long-term development [23].
