Water and Environmental Testing

Gravimetric analysis is a technique wherein the amount of an analyte can be determined through the measurement of mass. Gravimetric analysis depends on comparing the masses of two compounds containing the analyte. It involves isolation of an ion in a solution by a precipitation reaction, filtering, washing the precipitate free of contaminants, conversion of the precipitate to a product of known composition, then weighing the precipitate, and determining the difference in mass. From the mass and known composition of the precipitate, the amount of the original ion can be determined.

Volumetric analysis also known as titrimetric analysis is an analytical technique that involves measurement of volume from a solution with known concentration which is used to determine the concentration of the analyte.

Colorimetric analysis is an analytical technique that determines the concentration of an analyte by observing color changes in solutions. This method utilizes a specialized spectrometer known as a UV-Vis spectrophotometer, which measures the intensity of light absorbed or transmitted by the solution. The intensity of light is directly proportional to the concentration of the colored solution, allowing for precise quantitative analysis.

• Quantitative Determination: Accurately measures the concentration of various analytes in a solution, making it essential for chemical analysis.
• Versatility: Applicable to a wide range of fields, including environmental monitoring, clinical diagnostics, and industrial quality control.
• Non-Destructive Testing: Allows for the analysis of samples without altering or destroying them, preserving their integrity for further testing.

Colorimetric analysis is a reliable and efficient method for determining the concentration of substances in various solutions. Its precision and versatility make it a valuable tool in both research and industrial applications.
