Therefore, the resin gels were subjected to microwave-assisted digestion in 5 mL of HNO3 and 1 mL of H2O2 (Fluka, TraceSELECT) using a Multiwave 3000 (Anton Paar, Graz, Austria) microwave instrument for measuring the amount of analyte taken up by the gels.
The area sampled (As) and the area analyte coated (Ad) and the recovery (R) were statistically measured, allowing the amount of analyte sampled to be calculated.
However, as a larger fraction of the immobilized receptor is bound, the amount of analyte being measured will slowly increase.
Measure out a precise amount of analyte (the reactant mixed in with the unknown).
Defined amount of analyte was injected to measuring cell after sensor stabilization (current baseline).
The recovery of the standard spike was calculated as ([measured amount of analyte in spiked hydrolysate] - [measured amount of analyte in unspiked hydrolysate])/[amount of analyte spiked in] × 100%.
In this study, generalized expressions for SPR response factor and effective refractive index are developed to measure rates of analyte sorption onto 3-D surfaces.
However our findings are similar to other studies that used one-time measures of these analytes.
However, in contrast, high performance liquid chromatography (HPLC) [18, 29, 30] is capable of measuring all parameters noted in Scheme 1. Within the field of gastroenterology, HPLC has been predominantly used to measure levels of analytes in tissue homogenates [18, 28, 30] and hence only intracellular neurochemicals are monitored, meaning the release of 5-HT from EC cells is entirely missed.
Hence, a high number of studies are dedicated to this objective and some of them also include the measuring of peripheral analyte levels.
