The purpose of drying is to lower the moisture content in order to guarantee conditions favourable for storage or for further processing or handling of the product.
The purpose of extraction and drying is to obtain samples that are free of hydrocarbons, water and soluble salts that are suitable for further analysis.
Analytical chemistry is concerned with investigation of the quantitative and/or qualitative characteristics of a given sample. For instance, an analytical chemist may qualitatively determine what the various polycyclic aromatic hydrocarbons in a tar sample are, and may also quantitatively analyze the concentrations of each species in the sample.
A hollow cathode lamp is used in analytical chemistry techniques to produce specific wavelengths of light for atomic absorption spectroscopy. This lamp helps to excite atoms in a sample, allowing for accurate measurement of their concentration in the sample.
This would fall under the branch of analytical chemistry, which focuses on identifying and quantifying the chemical components present in a sample. In forensic science, analytical chemistry techniques are often used to analyze evidence such as blood, drugs, or trace materials found at a crime scene.
Liquid and gas sampling in analytical chemistry involves collecting representative samples for analysis, typically using techniques such as syringes, pipettes, or gas collection bags. The collected samples are then analyzed using various analytical techniques to determine the composition and concentration of substances present in the liquid or gas sample. Proper sampling techniques are crucial to ensure the accuracy and reliability of the analytical results.
You can determine if a sample is more contaminated than another by comparing the levels of contaminants present in each sample. This can be done through analytical testing methods such as chemical analysis or microbiological testing. The sample with higher concentrations of contaminants is considered more contaminated than the sample with lower concentrations.
The purpose is to obtain a statistical representative sample from the material to be tested.
This branch of chemistry is called analytical chemistry.

Determining the composition of a moon rock sample would fall under analytical chemistry, which focuses on determining the chemical makeup of substances and materials. This process involves using various instruments and techniques to analyze the elements and compounds present in the sample.
The analytical chemistry; also is a problem of geochemistry or cosmochemistry.
A hollow cathode lamp is used in analytical chemistry techniques to produce specific wavelengths of light for atomic absorption spectroscopy. This lamp helps to excite atoms in a sample, allowing for accurate measurement of their concentration in the sample.
Drying a sample helps remove moisture or solvents, allowing for accurate measurements of the sample's weight or composition. It also prevents microbial growth and ensures stability during storage and analysis.

An absorption spectrum in analytical chemistry shows how a substance absorbs light at different wavelengths, while a standard curve is a graph that relates the concentration of a substance to its measured signal, helping to quantify the amount of that substance in a sample.
Hollow cathode lamps are used in analytical chemistry techniques to produce specific wavelengths of light for atomic absorption spectroscopy. This light helps identify and quantify elements in a sample by measuring the absorption of light at characteristic wavelengths.
