“…The standard curve was obtained by plotting Trolox concentrations against the average net AUC of the two measurements for each concentration. Final ORAC values were calculated using a regression equation between Trolox concentration and the net AUC and were expressed as micromole Trolox equivalents per gram fresh weight (Huang et al, 2002;Prior et al, 2003).…”

Raspberries are a delicate, high-value crop with an extremely short shelf life exacerbated by postharvest decay caused by Botrytis cinerea Pers. European red raspberry (Rubus idaeus L.) is the most widely grown variety. Yellow (R. idaeus L.), black (R. occidentalis L.), and purple raspberries (R. ×neglectus Peck. or R. occidentalis ×idaeus hybrids) are available mainly at local markets and U-pick farms. To compare the postharvest quality of the raspberry color groups, pesticide-free fruit from cultivars and breeding selections of red, yellow, purple, and black raspberries were examined for oxygen radical absorbance capacity (ORAC), phenolics, anthocyanins, soluble solids, titratable acids, pH, color, firmness, decay and juice leakage rates, ethylene evolution, and respiration. There were significant correlations between decay rate and physiochemical properties. Both decay and leakage rates were correlated with weather conditions before harvest, but each color group responded differently to different weather factors. There were no correlations among changes in color, firmness, decay, or juice leakage rates. All the other color groups were less acidic than the familiar red raspberry. Yellow raspberries had the worst decay rates but the best leakage rates. Black and purple raspberries, with the highest phenolics and anthocyanins and the lowest ethylene evolution rates, resisted decay the longest but bled soonest.

“…However, when the liquids are aspirated into the system, the devices used tend to insert air bubbles in the system; as a result, liquid propulsion has been employed more recently instead of aspiration. Peristaltic pumps [14][15][16], automatic burettes [17,18] or syringe pumps [19] have been employed for propelling the liquids in these systems.…”

“…A flow system for the chemiluminometric quantitation of propanolol has been developed using two 2-way solenoid valves and two automatic burettes for the liquids propulsion. The versatility of combining the use of both 2-way and 3-way solenoid valves in the same manifold has been demonstrated in the spectrophotometric determinations of amiloride hydrochloride [37] and trimipramine [19] in pharmaceutical preparations. In both cases, the flow system is designed in order to perform the required chemical reaction on-line, combining binarysampling with a dual-stopped flow strategy or with flowreversal, respectively.…”

Multicommutation is a methodology of increasing use for the development of chemical analysis systems. Specifically, it refers to continuous-flow configurations designed with computer-controlled commutators. The flow system, based on the implementation of solenoid valves in Flow Injection Analysis (FIA), is called Multicommutated Flow System (MCFIA). These flow systems can be easily re-configured by just changing the procedure with the software, resulting in increased versatility, potential for automation and minimization of both reagent consumption and waste generation. The use of solenoid pumps for propelling the solutions has been recently introduced and is known as Multipumping Flow Systems (MPFS). Finally, Multisyringe Flow Injection Analysis (MSFIA) has been developed implementing multicommutation principles in a modified Sequential Injection Analysis (SIA) system. This review covers a brief description about the fundamentals of the above mentioned methodologies as well as their application to pharmaceutical and clinical analysis. Several examples are given and some particular aspects are highlighted, such as the differences between measuring the analytical signal in solution or on a solid support (flow-through optosensor), a detailed classification of the reported methods in terms of the flow technique employed, or the novelty of each published method.
