Analytical chemistry; List of materials analysis methods This page was last edited on 14 November 2023, at 15:12 (UTC). Text is available under the Creative Commons ...
Analytical chemistry has been important since the early days of chemistry, providing methods for determining which elements and chemicals are present in the object in question. During this period, significant contributions to analytical chemistry included the development of systematic elemental analysis by Justus von Liebig and systematized ...
In literary interpretation, paratext is material that surrounds a published main text (e.g., the story, non-fiction description, poems, etc.) supplied by the authors ...
Within chemistry, a Job plot, otherwise known as the method of continuous variation or Job's method, is a method used in analytical chemistry to determine the stoichiometry of a binding event. The method is named after Paul Job and is also used in instrumental analysis and advanced chemical equilibrium texts and research articles.
Chemometrics is the science of extracting information from chemical systems by data-driven means. Chemometrics is inherently interdisciplinary, using methods frequently employed in core data-analytic disciplines such as multivariate statistics, applied mathematics, and computer science, in order to address problems in chemistry, biochemistry, medicine, biology and chemical engineering.
A normal experiment may involve 1–10 mL solution with an analyte concentration between 1 and 10 mmol/L. More advanced voltammetric techniques can work with microliter volumes and down to nanomolar concentrations. Chemically modified electrodes are employed for the analysis of organic and inorganic samples.
As a real-time trace gas analysis method based on mass spectrometry, PTR-MS has two obvious limitations: Isomers cannot be easily separated (for some it is possible by switching the reagent ions [9] or by changing the reduced electric field strength in the drift tube) and the sample has to be in the gas phase. Countermeasures against these ...
In analytical chemistry, sample preparation (working-up) refers to the ways in which a sample is treated prior to its analyses. Preparation is a very important step in most analytical techniques, because the techniques are often not responsive to the analyte in its in-situ form, or the results are distorted by interfering species .
