About

Qinhan Jin is a pioneering figure in the development of advanced instrumentation for atomic spectrometry and surface plasmon resonance (SPR) sensing. His key research areas include ultrasonic nebulization for atomic spectroscopy and multiwavelength optical detection techniques. Jin’s most notable contribution is the invention of an inexpensive continuous-type ultrasonic nebulizer, which dramatically improved aerosol introduction rates to approximately 1.0 mL/min—far surpassing traditional pneumatic nebulizers—while maintaining excellent long-term stability. This work, published in 2000 and cited 13 times, provided a cost-effective solution for enhancing sensitivity in atomic spectrometry. Additionally, Jin introduced a novel SPR instrument based on simultaneous multiwavelength detection, moving beyond conventional angle-modulated SPR devices. By analyzing reflected spectra across multiple wavelengths, his design enabled more robust and versatile sensing, a contribution that has garnered 5 citations. These achievements highlight Jin’s impact on making analytical instrumentation more accessible and efficient, particularly for environmental and biomedical applications. His work continues to inspire researchers seeking low-cost, high-performance tools for trace element analysis and real-time biomolecular interaction monitoring.
