'Labile' and total aluminium concentrations, Allabile and Altotal, respectively, were determined by measuring the sample before and after UV irradiation by amperometry at +0.6 V.
The chord magnetic susceptibility (χ = M/H) can be obtained by measuring the sample's magnetization (M) induced by a weak external dc/ac field (H).
μli (E) can be determined in different configurations, either directly by measuring the sample transmission, or indirectly, e.g. by measuring XRF or electron yields, as a function of the energy of the incoming X-ray.
It is demonstrated that the procedure for determination of oxidative stability of oils can be significantly simplified and performed by measuring the sample emission at only one spectral region centered at 2900 nm.
The cross calibration factor of the scanner (Bq per ml/cps per voxel) was determined once per week using a cylindrical water phantom (25-cm length and 20-cm inner diameter) filled with 18F solutions and by measuring the sample activity of the 18F solutions at the well counter (BSS-3: Shimadzu Co., Ltd., Kyoto, Japan) [14].
Specifically, the biochemical content of each sample was assessed by measuring the sample wet weight, lyophilizing, and then measuring the dry weight.
Averaged spectra were obtained by measuring the sample for 120 s, leaving the sample in the dark for 1 min, and then repeating this cycle over 4 6 h.
In our study, we quantified these two processes by measuring the sample weight and moisture and calculated the loss of dry solids.
Volume changes associated with the compression were estimated by measuring the sample dimensions before and after compression with a toolmaker's microscope (Mitutoyo TM, Germany).
