Sample Collection and Analysis Methods

Flashcards covering key terms and concepts related to sample collection, preservation, and analysis methods.

Sampling

The process of collecting a representative sample of a material to analyze its components.

Homogenization

A method to mix samples to ensure a uniform composition throughout.

Preservation

The process of treating samples to prolong their storage life and maintain their properties.

Gas Sampling

The technique of collecting gas samples using devices like air pumps or sealed containers.

Storage Conditions

Specific environmental parameters such as temperature and humidity that must be maintained for sample integrity.

Conservation Agents

Substances added to samples to prevent degradation and maintain stability, often toxic and requiring careful handling.

Gravimetric Method

A technique involving weighing a sample before and after the removal of water to determine its water content.

Karl Fischer Titration

A chemical analysis method used to determine water content in a sample.

Thermogravimetric Analysis

A method that measures the change in weight of a sample as it is heated to assess moisture content.

Identification of Samples

Proper labeling including origin, date, material type, and hazards to ensure traceability and safety.
