A single particle transmitted into an ICP- mass spectrometer generates a ~1 ms pulse of ion signal (e.g., Figure a). Most ICP- mass spectrometers use sequential mass analyzers that can measure only one or two isotopes during this rapid single-particle detection event. This is insufficient for the detection of complex multi-element particles, which represent a substantial portion of manufactured nanomaterials used as additives in consumer products or which are formed by chemical modifications of pristine single-element particles after they have entered the natural environment.<\/p>\n<div class=\"page\" title=\"Page 1\">\n<div class=\"section\">\n<div class=\"layoutArea\">\n<div class=\"column\">\n<p>TOFWERK <a href=\"https:\/\/www.tofwerk.com\/ko\/icp\/\">icpTOF<\/a> simultaneously measures all isotopes, enabling determination of the complete chemical composition of single nanoparticles. In a previous application note (Multi-element Detection of Nanoparticles with icpTOF, 2016), we demonstrated the ability of the <a href=\"https:\/\/www.tofwerk.com\/ko\/icp\/\">icpTOF<\/a> to record all elements in single particles and compared multi-element <a href=\"https:\/\/www.tofwerk.com\/ko\/icp\/\">icpTOF<\/a> data to what can be recorded with modern sequential mass analyzers. Here, we show that the elemental composition of single steel nanoparticles in a polydisperse population can be quantified based on a simple multi-element solution calibration.<\/p>\n<figure id=\"attachment_12873\" aria-describedby=\"caption-attachment-12873\" style=\"width: 390px\" class=\"wp-caption aligncenter\"><img fetchpriority=\"high\" decoding=\"async\" class=\"wp-image-12873\" src=\"https:\/\/www.tofwerk.com\/wp-content\/uploads\/2017\/03\/Screen-Shot-2017-03-01-at-9.48.41-AM-1-300x193.png\" alt=\"\" width=\"400\" height=\"257\" srcset=\"https:\/\/www.tofwerk.com\/wp-content\/uploads\/2017\/03\/Screen-Shot-2017-03-01-at-9.48.41-AM-1-300x193.png 300w, https:\/\/www.tofwerk.com\/wp-content\/uploads\/2017\/03\/Screen-Shot-2017-03-01-at-9.48.41-AM-1-768x493.png 768w, https:\/\/www.tofwerk.com\/wp-content\/uploads\/2017\/03\/Screen-Shot-2017-03-01-at-9.48.41-AM-1-800x514.png 800w, https:\/\/www.tofwerk.com\/wp-content\/uploads\/2017\/03\/Screen-Shot-2017-03-01-at-9.48.41-AM-1-500x321.png 500w, https:\/\/www.tofwerk.com\/wp-content\/uploads\/2017\/03\/Screen-Shot-2017-03-01-at-9.48.41-AM-1.png 1000w\" sizes=\"(max-width: 400px) 100vw, 400px\" \/><figcaption id=\"caption-attachment-12873\" class=\"wp-caption-text\">Determining the elemental composition of single steel nanoparticles. Steel nanoparticles (IRMM-383) synthesized in the frame of the NanoDefine Project (http:\/\/www.nanodefine.eu\/index.php\/project-overview) were provided by Steffi Bo\u0308hme. Complete mass spectra (all isotopes) of single particles were recorded with the icpTOF using H2 in the Q-cell to reduce the interference of ArO+ and ArC+\u00a0with\u00a056Fe+and\u00a052Cr+, respectively. Figure a) shows the transient signal of Cr, Fe, Ni, and Mo from a single particle and figure b) the signals of many single particles recorded in a 20 second time period. The response of the icpTOF to individual elements figure c) was calibrated using standard solutions of Cr, Fe, Ni, and Mo in 1 % nitric acid in the concentration range of 0.1 -1 0 mg\/g. This calibration was used to determine the concentration (c) of each element in every single particle, and element fractions for each particle were calculated using 100 % normalization method (c(Fe)+c(Cr)+c(Ni)+c(Mo)=100%). The table compares element fractions used for synthesis of these particles to the mean element fractions of 1900 single particles measured with the icpTOF.<\/figcaption><\/figure>\n<div class=\"page\" title=\"Page 1\"><\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Olga Borovinskaya, Steffi Boehme TOFWERK, RIKILT, The Netherlands Single particle inductively coupled plasma mass spectrometry (sp-ICP- MS) has established itself as a robust and sensitive method for the measurement of nanoparticle size and number concentration at environmentally relevant levels.
