Sentence examples for Two spe from inspiring English sources

MCX and MAX SPE fractions were analysed separately to minimize interferences and to determine the fraction of each analyte eluting from the two SPE cartridges.

While for the most dilute systems (n = 20) the two SPE families show similar ionic conductivities in the entire temperature range investigated (273-343 K), for n = 6 and n = 9 they differ significantly; at room temperature, the NaFSI based SPEs show lower ionic conductivities than the NaTFSI based analogues.

Most of the restatement came from the consolidation of two SPEs.
