说明

應用

• An Approach Based on an Increased Bandpass for Enabling the Use of Internal Standards in Single Particle ICP-MS: Application to AuNPs Characterization.: This study by Bazo et al. (2023) explores the use of Tetramethylammonium hydroxide solution to enhance internal standard applications in single particle ICP-MS for gold nanoparticle characterization. This method improves accuracy and reliability in nanoparticle detection (Bazo et al., 2023).


• Titanium dioxide nanoparticles assessment in seaweeds by single particle inductively coupled plasma - Mass spectrometry.: López-Mayán et al. (2022) utilized Tetramethylammonium hydroxide solution for the assessment of titanium dioxide nanoparticles in seaweeds. This approach allows for precise quantification and analysis of nanoparticles in complex matrices (López-Mayán et al., 2022).


• Determination of selenite and selenomethionine in kefir grains by reversed-phase high-performance liquid chromatography-inductively coupled plasma-optical emission spectrometry.: Bodur et al. (2021) used Tetramethylammonium hydroxide solution to effectively separate and quantify selenite and selenomethionine in kefir grains, demonstrating its utility in food chemistry applications (Bodur et al., 2021).


• Application of TMAH thermochemolysis to the detection of nucleobases: Application to the MOMA and SAM space experiment.: He et al. (2019) applied Tetramethylammonium hydroxide solution in thermochemolysis for detecting nucleobases in space mission experiments, demonstrating its application in astrobiology and space chemistry (He et al., 2019).
