When there is doubt, the law requires a "match flame test" of a sample quantity.
Finally, the influence of the extraction time and the sample quantity were also studied.
Fold change was calculated by dividing the normalized post-treatment sample quantity with the normalized untreated control quantity from the same animal, and calculating the average of fold changes for each species.
In most cases sufficient sample quantity is available to cut the sample to fit the available window size of SIMS sample holders.
First, the design of the survey scheme was introduced, including selection of items, estimation of sample quantity, and selection of locations.
The non-reacting FLUENT CFD calculations give a quantitative estimate of the sample quantity as well as the fluid mixing and thermal history.
Firstly, although human biopsy samples at different OA stages represent the real progression of OA and retain the native PCM and ECM, they also suffer from disadvantages such as small sample volume, limited sample quantity, and restricted location for sample collection.
These developments greatly facilitate the study of highly air-sensitive samples particularly in cases where sample quantity is a limiting factor, as is often the case for samples of biological origin.
The ultrasonic extraction conditions of the 11 analytes including sample quantity, methanol concentration and extraction time were simultaneously optimized with a Box Behnken design (BBD) and Derringer's desirability function.
