  2. Electroanalytical methods - Wikipedia

    en.wikipedia.org/wiki/Electroanalytical_methods

    This method, in practical terms, is non-destructive since only a very small amount of the analyte is consumed at the two-dimensional surface of the working and auxiliary electrodes. In practice, the analyte solution is usually disposed of since it is difficult to separate the analyte from the bulk electrolyte , and the experiment requires a ...

  3. Analytical chemistry - Wikipedia

    en.wikipedia.org/wiki/Analytical_chemistry

    Analytical chemistry studies and uses instruments and methods to separate, identify, and quantify matter. [1] In practice, separation, identification or quantification may constitute the entire analysis or be combined with another method. Separation isolates analytes.

  4. Process analytical chemistry - Wikipedia

    en.wikipedia.org/wiki/Process_analytical_chemistry

    Process analytical chemistry (PAC) is the application of analytical chemistry with specialized techniques, algorithms, and sampling equipment for solving problems related to chemical processes. It is a specialized form of analytical chemistry used for process manufacturing similar to process analytical technology (PAT) used in the ...

    en.wikipedia.org/wiki/Job_plot

    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.

  6. Sentiment analysis - Wikipedia

    en.wikipedia.org/wiki/Sentiment_analysis

    In general, the utility for practical commercial tasks of sentiment analysis as it is defined in academic research has been called into question, mostly since the simple one-dimensional model of sentiment from negative to positive yields rather little actionable information for a client worrying about the effect of public discourse on e.g ...

    en.wikipedia.org/wiki/Instrumental_chemistry

    Instrumental analysis is a field of analytical chemistry that investigates analytes using scientific instruments. Block diagram of an analytical instrument showing the stimulus and measurement of response

  8. Qualitative inorganic analysis - Wikipedia

    en.wikipedia.org/wiki/Qualitative_inorganic_analysis

    Classical qualitative inorganic analysis is a method of analytical chemistry which seeks to find the elemental composition of inorganic compounds. It is mainly focused on detecting ions in an aqueous solution , therefore materials in other forms may need to be brought to this state before using standard methods.

    Protein folding problem: Is it possible to predict the secondary, tertiary and quaternary structure of a polypeptide sequence based solely on the sequence and environmental information? Inverse protein-folding problem: Is it possible to design a polypeptide sequence which will adopt a given structure under certain environmental conditions?
