Micro-hole array sprayer combined with an organic membrane to assist LIBS (MASOM-LIBS): A novel highly sensitive detection method for dissolved trace heavy metals in water

Atomic spectrometry update: review of advances in atomic spectrometry and related techniques

“…A novel, highly sensitive detection method for dissolved trace heavy metals in water was developed by Shang et al 109 The method was based on the transformation of water samples into micrometer droplets, using a micro-hole array injection device. Droplets were then sprayed onto a rotating polypropylene organic film and let dry before LIBS analysis.…”

Preparing microparticles on an elementary substrate using a micro-hole array sprayer to assist LIBS: a highly sensitive trace rare earth element detection method for aqueous solution analysis

“…In a previous study by our research group, the MHASOFM-LIBS 15 system was proposed, which utilized a micro-hole array sprayer and an organic membrane to rapidly prepare large, continuous, and uniform surfaces. This system used a minimal amount of sample solution to achieve limits of detection for heavy metal elements below 0.1 mg L −1 within a 3 minute detection time, effectively addressing the issues associated with the previous methods and providing valuable insights for the present study.…”
