The measured current is indicative of electron transfer within the sample and at the electrode surface, and thus, the concentration of the analyte. In chronoamperometry, the electrical potential at the working electrode is applied in steps, and the resulting current is measured as a function of time. The applied electrical potential can also be held constant or varied with time as the current is measured.","tracks":[{"project":"LitCovid-PD-CLO","denotations":[{"id":"T610","span":{"begin":91,"end":92},"obj":"http://purl.obolibrary.org/obo/CLO_0001020"},{"id":"T611","span":{"begin":497,"end":498},"obj":"http://purl.obolibrary.org/obo/CLO_0001020"}],"attributes":[{"subj":"T610","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T611","pred":"source","obj":"LitCovid-PD-CLO"}]},{"project":"LitCovid-PD-CHEBI","denotations":[{"id":"T164","span":{"begin":253,"end":261},"obj":"Chemical"}],"attributes":[{"id":"A94299","pred":"chebi_id","subj":"T164","obj":"http://purl.obolibrary.org/obo/CHEBI_10545"},{"subj":"T164","pred":"source","obj":"LitCovid-PD-CHEBI"}]},{"project":"LitCovid-PD-GO-BP","denotations":[{"id":"T39","span":{"begin":253,"end":270},"obj":"http://purl.obolibrary.org/obo/GO_0022904"}],"attributes":[{"subj":"T39","pred":"source","obj":"LitCovid-PD-GO-BP"}]},{"project":"LitCovid-sentences","denotations":[{"id":"T754","span":{"begin":0,"end":214},"obj":"Sentence"},{"id":"T755","span":{"begin":215,"end":362},"obj":"Sentence"},{"id":"T756","span":{"begin":363,"end":516},"obj":"Sentence"},{"id":"T757","span":{"begin":517,"end":623},"obj":"Sentence"}],"namespaces":[{"prefix":"_base","uri":"http://pubannotation.org/ontology/tao.owl#"}],"attributes":[{"subj":"T754","pred":"source","obj":"LitCovid-sentences"},{"subj":"T755","pred":"source","obj":"LitCovid-sentences"},{"subj":"T756","pred":"source","obj":"LitCovid-sentences"},{"subj":"T757","pred":"source","obj":"LitCovid-sentences"}]}],"config":{"attribute types":[{"pred":"source","value type":"selection","values":[{"id":"LitCovid-PD-CLO","color":"#ecb293","default":true},{"id":"LitCovid-PD-CHEBI","color":"#9893ec"},{"id":"LitCovid-PD-GO-BP","color":"#a7ec93"},{"id":"LitCovid-sentences","color":"#ec93c1"}]}]}}
