Chromatography in Water Quality Analysis
Chromatography is an analytical technique used to separate and quantify components within a mixture based on their chemical properties and interactions. Due to its precision and sensitivity, chromatography is widely utilized for water quality analysis due to its widespread usage. Common techniques employed for water analysis include high-performance liquid chromatography (HPLC) and gas chromatography (GC).
Chromatography can be used to detect and quantify various analytes found in water, such as organic compounds, pesticides, pharmaceuticals and contaminants like heavy metals. To perform accurate analyses, special vials designed specifically for this process are needed.
The Role of Chromatography Vials
Chromatography vials are small glass or plastic containers used to hold samples that need to be analyzed for analysis, playing an essential role in ensuring sample integrity and the precision of results. Here's how chromatography vials contribute to water quality analysis:
Sample Integrity: Chromatography vials are designed to protect the integrity of samples. They typically consist of chemically inert materials to avoid interactions between samples and vials that might alter results.
Minimizing Contamination: Vials must be tightly sealed to avoid external sources contaminating them, and any small contaminants could impede on the accuracy of analysis.
Sample Volume Control: Vials come in various sizes to enable precise control over sample volumes for accurate quantification of analytes in water samples.
Compatibility: Chromatography vials are designed to work seamlessly with the instrument being used, making introduction of samples smooth and efficient. Autosamplers should easily accommodate them for seamless introduction.
Chemically Resistant Vials: Vials must be resistant to the solvents and chemicals commonly used in chromatography to ensure they don't interact with samples or mobile phases, potentially destabilizing analyses. This ensures that vial materials do not react with either sample material or mobile phase reactions that could compromise analysis results.
