Ag brath ar infhaighteacht, bainfear úsáid as foirmeacha cobhsaí iseatóp-lipéadaithe den anailít, a oireann go háirithe do bhrath mais-speictriméadrach, nó as comhdhúile analógacha a bhfuil dlúthghaol struchtúrach acu leis an anailít. Nuair nach féidir aon chaighdeán oiriúnach inmheánach a úsáid, moltar sainaithint na hanailíte a dheimhniú le comhchrómatagrafaíocht. Sa chás sin ní bhfaighfear ach aon bhuaic amháin, agus beidh an bhuaicairde (nó an buaicachar) feabhsaithe coibhéiseach le méid na hanailíte breise. Mura bhfuil sé sin indéanta, úsáidfear caighdeáin mhaitrísmheaitseáilte nó mhaitrístreisithe.
When required according to the confirmatory method, a suitable internal standard shall be added to the test portion at the beginning of the extraction procedure. Depending on availability, either stable isotope-labelled forms of the analyte, which are particularly suited for mass spectrometric detection, or analogue compounds that are structurally closely related to the analyte, shall be used. When no suitable internal standard can be used, the identification of the analyte shall preferably be confirmed by co-chromatography. In this case only one peak shall be obtained, the enhanced peak height (or area) being equivalent to the amount of added analyte. If this is not practicable, matrix-matched or matrix-fortified standards shall be used.
