Taking advantage of the capabilities of reversed micelles as universal solubilization media, the composite tyrosinase electrode was used for the determination of benzoic acid in two different kind of samples: mayonnaise sauce, which is a highly hydrophobic matrix, and Cola soft drinks, a hydrophilic matrix for which practically no sample treatment is necessary.
The real time-PCR method was carefully validated by using more than 200 references and field strains with different kinds of sample preparation techniques on artificially contaminated and naturally infected samples.
Different kinds of samples were tested: non-treated, plasma nitrided, ZrBN-triode sputtered and ZrBN-duplex treated samples.
The enzymatic reaction produces hydrogen peroxide, which has been chronoamperometrically monitored and related to FA concentration in different kinds of samples.
The test is robust, has a low detection limit (c.a. 5 to 50 genome copies in the PCR reaction microwell) and is promising for monitoring BoNT-producing Clostridia in different kinds of samples including food and clinical samples.
Moderator analyses confirm that these weak effects are generally consistent (and often non-significant) across a variety of methodological conditions (e.g., different outcome measures, different kinds of samples).
As a case study of controllable synthesis based on the QSPR model, the new LDH of Mg Al CO3 system with the desired basal spacing 7.6 Å, which was screened out from a list of LDH dataset consisting of 30 different kinds of samples, was verified by our experiment with the relative error equal to 0.93%.
Among the various rapid-detection techniques, immunoassay is the most widely used one because of its adaptability of different kinds of samples and its convenience of operation.
The experimental work conducted here is also important to shed light on the relative merits of these different kinds of samples for historic paint analysis.
