Provided is a method for determining the concentration of a sample solution with which the concentration of a sample solution is quantitatively determined by measuring the chemiluminescent intensity generated inside a reactor (2), which is characterized in that the reactor (2) is an in-series ...
risk of sample loss during transfer to the volumetric flask. Only an approximate amount of sample needs to be weighed in− making it easier and much faster−because the variable amount of solvent added compensates for over or under-target samples, to always achieve the precise concentrati...
Suppose you have a sample which has strong absorbance at265nm.It is too strong for the spectrophotometer.You dilute the sample in the following way:you use a100.00mL volumeteric flask; you add10.00mL of the sample to that f...
摘要: PROBLEM TO BE SOLVED: To provide a sample preparation apparatus capable of performing fixation of a sample and washing of a supply route (passage) of staining solution without complicating the structure of the apparatus.年份: 2007
When multiple faults occur in a transformer, the concentration of gases becomes complicated. The inter-relation among different gases becomes complex, which do not match the predefined values. In such cases, FL is useful for handling the uncertain and imprecise information. The workflow of a fuzzy...
solution, the improvement including mixing the solution with one or more particulate reagents to form a suspension, thereby modifying the solution to yield a concentration of total detectable substance which correlates with the concentration of original analyte, and passing the solution through the ...
aChemical analyses can be made by determining how much of a solution of known concentration is needed to react fully with an unknown test sample. 化学分析可以通过确定多少做已知的集中的解答是需要的充分地起反应与一个未知的测试样品。[translate]...
Microfluidic paper-based analytical devices (μPADs) are a promising solution for a wide range of point-of-care applications. The feasibility of inducing ion concentration polarization (ICP) on μPADs has thus far attracted little attention. Accordingly, this study commences by demonstrating the ICP...
For symptomatic patients, viral load is highest around the onset of symptoms and decreases shortly after. When a low concentration of SARS-CoV-2 virus is diluted into a pool of negative samples there will be a risk that levels are close to the limit of detection, thus increasing false-...
Peptide preparation involves reduction and alkylation of cysteines, digestion of the sample into peptides, desalting and concentration of the peptides and final analysis of these peptides by ionization (e.g., ESI) plus orbitrap-based...
