These compounds are widely used as additive flame retardants and plasticizers in different types of materials and have become ubiquitous pollutants in indoor environments. When using collision\u2010induced dissociation in PICI mode the fragmentation of the organophosphate triesters can be performed in a more controllable way than in electron ionization (EI) mode. The developed selected\u2010reaction monitoring method provided high selectivity for the investigated compounds. For 8\u2010h air measurements (corresponding to 1.5\u2009m\n                    <jats:sup>3<\/jats:sup>\n                    of sampled air) the limit of detection of the method was determined to be in the range 0.1\u20131.4\u2009ng\u2009m\n                    <jats:sup>\u22123<\/jats:sup>\n                    , which is comparable with nitrogen\u2010phosphorus detection and about 50\u2010fold lower than when using EI in selected\u2010ion monitoring mode. The presented method was applied to samples from three common indoor environments, in which a number of organophosphate triesters were identified and quantified. The dominating compound was found to be tris(2\u2010chloropropyl) phosphate, which occurred at levels up to 0.8\u2009\u03bcg\u2009m\n                    <jats:sup>\u22123<\/jats:sup>\n                    .
