Low-cost methodology

The use of LC-ARC or 96-well microtiter plates containing solid scintillant, in contrast, represents low-cost methodologies to improve the sensitivity of the semi-quantitative analysis of metabolites. The LC-ARC and 96-well microtiter plate approaches have similar LOD for 14C and 3H and both can be used in combination with MS to generate quantitative and structural data. Both approaches are particularly useful in cases where the sample is limited. The throughput of LC-ARC is higher than for the plate approach due to the need to dry and count the plates offline. However, the 96-well plate approach is nondestructive, such that drug-related components can be subsequently eluted from the plates for further analysis, if necessary. [Pg.268]

Recent studies have explored different mechanisms of antimicrobial action by designing hybrid nanomaterials that provide a new approach to killing microbes. One option employs a low-cost methodology to prepare nanosized copper-PANI nanocomposite materials with enhanced antibacterial and antifungal properties. Copper oxide nanocrystals immobilised in a PANI matrix coated onto fabrics for the improvement of antimicrobial activity could be an excellent application in coating technology. [Pg.280]

Separation and detection methods A survey on determination of tin species in environmental samples has been published by Leroy et al. (1998). A more detailed overview of GS-MS methodology has been published by Morabito et al. 1995) and on sample preparation using supercritical fluid extraction has been described by Bayona (1995)- The techniques are now under control, so that routine procedures are available at a relatively low cost (Leroy et al. 1998). [Pg.82]

A PC interfaced with a microscope photometer provides a powerful analytical tool working down to cellular and subcellular levels (with polarized light). With the relatively low cost of modem PCs and the wide availability of surplus components for light microscopy, the methodology is available to anyone who can combine microscopy with computer... [Pg.156]

Twenty years ago the main applications of electrochemistry were trace-metal analysis (polarography and anodic stripping voltammetry) and selective-ion assay (pH, pNa, pK via potentiometry). A secondary focus was the use of voltammetry to characterize transition-metal coordination complexes (metal-ligand stoichiometry, stability constants, and oxidation-reduction thermodynamics). With the commercial development of (1) low-cost, reliable poten-tiostats (2) pure, inert glassy-carbon electrodes and (3) ultrapure, dry aptotic solvents, molecular characterization via electrochemical methodologies has become accessible to nonspecialists (analogous to carbon-13 NMR and GC/MS). [Pg.517]

Murashige [48] has proposed the concept of artificial seed as an approach to the mass propagation of elite plant varieties. Artificial seeds are expected to be a reliable delivery system for the clonal propagation of elite plants [49-51]. The delivery system has the potential for genetic uniformity, high yield, and low cost of production. Hairy root methodology is one of the promising candidates as material for artificial seed. [Pg.164]

The enantioselective decarboxylative protonation, which is directly related to the venerable malonic add synthesis, has not shown the major advances in terms of selectivity that we could have expected for the oldest methodology used to carry out enantioselective protonations (Marckwald, 1904). The use of this reaction and, in particular, of its organocatalyzed version for the synthesis of compounds of biological significance is now emerging. This highlights the synthetic potential of this low-cost and operationally simple reaction, notably in the context of sustainable chemistry. However, this asymmetric reaction is not yet mature. Further investigations... [Pg.191]
