trí ian shonracha le haghaidh LRMS;
three specific ions for LRMS;
Tá an mhais-speictriméadracht ísealtaifigh (LRMS de réir taifeach aonaid maise) agus mais-speictriméadracht ardtaifigh (HRMS), lena n-áirítear e.g. Teascóga fócasaithe dúbailte, Am Eitilte (TOF) agus uirlisí Orbitrap iomchuí.
Both low-resolution mass spectrometry (LRMS, at unit mass resolution) and high-resolution mass spectrometry (HRMS), including e.g. double focusing sectors, Time of Flight (TOF) and Orbitrap instruments are appropriate.
I gcás ina ndéantar cinneadh mais-speictriméadrach trí speictream lánscanta (LRMS agus HRMS araon) a thaifeadadh, ní bheidh oiriúnach ach iain dhiagnóiseacha lena ngabhann déine choibhneasta níos mó ná 10 % i speictream tagartha an chaighdeáin calabrúcháin, an chaighdeáin mhaitrísmheaitseáilte nó na gcaighdeán maitrístreisithe.
When mass spectrometric determination is performed by the recording of full scan spectra (both LRMS and HRMS), only diagnostic ions with a relative intensity of more than 10 % in the reference spectrum of the calibration standard, matrix-matched standard or matrix-fortified standards are suitable.
