Leucovorin (LV) and methotrexate (MTX) were determined in human blood serum samples by using a model based in the net analytical signal concept. The calibration method used is a variation of the original hybrid linear analysis (HLA) method, developed by Goicoechea and Olivieri (HLA/GO). The calibration set was composed by nine serum samples with different amounts of LV and MTX in the range of 0-10...
The influence of different factors on the room-temperature phosphorescence (RTP) emission from the inclusion complex between α-cyclodextrin (α-CD) and 6-bromo-2-naphthol (BN) was analyzed. Although RTP signals are detected even in aerated solutions, an efficient enhancement of the phosphorescence emission (about 13 times) is obtained when the solutions of the complex are deaerated with nitrogen bubbling,...
