Analytical chemistry studies and uses instruments and methods used to separate, identify and quantify matter. In practice separation, identification or quantification may constitute the entire analysis or be combined with another method. Qualitative analysis identifies analytes, while quantitative analysis determines the numerical amount or concentration. Analytical chemistry consists of classical, wet chemical methods and modern, instrumental methods.
Many mistakenly think the two terms can be used interchangeably. So what is the difference between Qualitative Research and Quantitative Research? Qualitative Research Qualitative Research is primarily exploratory research.
It is used to gain an understanding of underlying reasons, opinions, and motivations.
It provides insights into the problem or helps to develop ideas or hypotheses for potential quantitative research. Qualitative Research is also used to uncover trends in thought and opinions, and dive deeper into the problem.
Qualitative data collection methods vary using unstructured or semi-structured techniques.
The sample size is typically small, and respondents are selected to fulfil a given quota. Quantitative Research Quantitative Research is used to quantify the problem by way of generating numerical data or data that can be transformed into usable statistics.
It is used to quantify attitudes, opinions, behaviors, and other defined variables — and generalize results from a larger sample population. Quantitative Research uses measurable data to formulate facts and uncover patterns in research.
Quantitative data collection methods are much more structured than Qualitative data collection methods. Quantitative data collection methods include various forms of surveys — online surveys, paper surveysmobile surveys and kiosk surveys, face-to-face interviews, telephone interviews, longitudinal studies, website interceptors, online polls, and systematic observations.

Although modern analytical chemistry is dominated by sophisticated instrumentation, the roots of analytical chemistry and some of the principles used in modern instruments are from traditional techniques, many of which are still used today.

Jul 23, · Qualitative and quantitative analysis are two fundamental methods of collecting and interpreting data in research. The methods can be used independently or concurrently since they all have the same objectives.
They have some errors, and so using them concurrently can compensate for the errors each has and then produce quality results. Chemistry 5 The Art and Science of Chemical Analysis Introduction to Chemical Analysis Chemical analysis includes any aspect of the chemical .
