Standard solutions refer to solutions with a precisely known concentration or composition. A primary standard is a highly pure, high molar mass, stable ...
Solutions vierges
A blank solution is a solution that does not contain the analyte, or the substance of interest being tested or measured. It is typically prepared using ...
Méthodes d'échantillonnage: présentation
A sample refers to a smaller subset representative of a larger population. In analytical chemistry, studying or analyzing an entire population is often ...
Méthodes d'échantillonnage: types d'échantillons
Sampling materials are classified into three main types: solid, liquid, and gas.
Solid samples include a variety of substances, such as sediments from ...
Plans d'échantillonnage
Sampling is a crucial step in analytical chemistry, allowing researchers to collect representative data from a large population. Common sampling methods ...
Préparation d'échantillons pour analyse: présentation
Sample preparation is an essential step in the analytical process. It involves preparing a sample so that it can be analyzed accurately. The goal is to ...
