For some cases, dilution is done to lower the reactivity of a reagent by increasing the distance between the nearby molecules of the same identity. This can be done by increasing the volume of the solvent or by taking an aliquot of the original solution and adding solvent...
Reproducibility of different laboratory of allowable error is defined in different laboratories, from the coal samples shrinkage aliquot out of the final stage of the coal samples with representative sample of repeated measurement results of average value (in a certain probability of critical value. 1.6...
These pooled samples were then subjected to centrifugation at 15,000g and 4 °C for 30 min to pellet the platelets and float chylomicrons, which were then removed from the top in a 0.1 ml aliquot [49]. The density of the remaining plasma samples (0.93 ml for each genotype) was ...
So far, more than 3000 radioactive isotopes are known with half-lives lasting from a few nanoseconds to billions of years. The definition of “short-lived” or “long-lived” strongly depends on the corresponding applications. While “short-lived cosmogenic radionuclides” can have half-lives of...
If the measurement results indicate trending (Crude B in Table 1), return the crude or crude/solvent sample to the separatory funnel and extract again using a new aliquot of hot DI water. If the measurement results indicate a successful extraction (...
(freeze-drying). Two 50 mL frozen aliquots of the cloud water sample and one 50 mL aliquot of the sample blank were lyophilized in 50 mL Falcon®that had been previously rinsed with ethanol and MilliQ water, covered with Parafilm®foil, and subjected to a Heto PowerDry LL3000 freeze-...
to readers from different backgrounds. The aim is to improve the knowledge and understanding of the subject of activated carbon for non-adsorption experts such as professionals in industry. Therefore, it is written in a comprehensible manner and dispenses with detailed explanations to complex ...
proceed for a total of 120 min. One mL aliquot digest from each flour sample was removed at 0, 20, 60, 90, and 120 min along the 2 h long intestinal digestion. The aliquots were immediately added with 80% (v/v) ethanol (Anchor Ethanol, Auckland, New Zealand) to deactivate the diges...
respectively. Saturated solution or a 6 mM flavonoid suspension was prepared in 20% PEG400/pH 7.4 buffer to be loaded into the donor compartment. A 300-µL aliquot in the receptor was collected at determined durations, followed by an immediate replacement with fresh receptor medium. The amount...
