Water Physical and Chemical TestingWater is a vital resource that sustains life on Earth. However, the quality of water can vary significantly, and it is essential to assess its physical and chemical parameters to ensure its safety and suitability for various applications. CD BioSciences, a leading name in the field of biological testing, offers comprehensive water physical and chemical testing services.
Water physical and chemical parameters refer to the characteristics and properties that are measured to assess the quality and suitability of water for specific purposes. These parameters provide valuable information about the composition, stability, and potential contaminants present in the water. Some of the key physical and chemical parameters that are commonly evaluated include pH, conductivity, total dissolved solids (TDS), turbidity, color, hardness, alkalinity, and the presence of specific ions or chemicals.

(Mateo P., et al., 2015)Accurate and reliable testing methods are crucial for assessing water's physical and chemical parameters. Several laboratory techniques are employed to measure these parameters, ensuring precise analysis and compliance with regulatory standards. The following methods are commonly utilized:
Spectrophotometry
Titration
Electrochemical Analysis
Atomic Absorption Spectroscopy (AAS)
CD BioSciences takes pride in offering comprehensive water physical and chemical testing services to ensure the safety and suitability of water for various applications.
pH
pH, a fundamental parameter, serves as a crucial indicator of water acidity or alkalinity. It is measured on a scale ranging from 0 to 14, where 7 denotes neutrality. Values below 7 signify acidity, while values above 7 indicate alkalinity. We employ cutting-edge equipment to ensure precise measurement of pH levels in water samples.
Conductivity
Conductivity serves as a significant parameter in assessing water's capacity to conduct electrical current. It is influenced by the presence of dissolved ions, including salts and metals. Measuring conductivity offers valuable insights into the overall content of dissolved solids in water, making it a useful indicator of water quality.
Total Dissolved Solids (TDS)
Total Dissolved Solids (TDS) refers to the cumulative concentration of inorganic and organic substances that are dissolved in water. This measurement encompasses minerals, salts, metals, and various other compounds. Elevated TDS levels can have an impact on the taste, odor, and overall suitability of water for specific applications. At CD BioSciences, we employ advanced techniques to precisely quantify TDS in water samples.
Turbidity
Turbidity serves as a crucial parameter in assessing the clarity of water, indicating the presence of suspended particles. These particles can originate from various sources, including inorganic matter such as sediment or mineral particles, as well as organic matter like algae or bacteria. We utilize cutting-edge instruments and techniques to accurately measure turbidity, providing valuable insights into water quality.
Color
Color in water can result from various sources, including dissolved organic matter, minerals, or the presence of certain chemicals. CD BioSciences utilizes the platinum-cobalt (Pt-Co) scale to measure color, allowing for a quantitative assessment of water quality. Color can impact the acceptability and treatment of water, making it an important parameter to consider.
Alkalinity
Alkalinity measures the ability of water to neutralize acids. It is primarily influenced by the presence of carbonates, bicarbonates, and hydroxides. Alkalinity levels can impact pH stability and the corrosiveness of water. CD BioSciences employs reliable methods to measure alkalinity accurately, providing valuable information for water quality assessment.
Hardness
Water hardness refers to the concentration of divalent cations, primarily calcium and magnesium ions, present in water. It is often measured in milligrams per liter (mg/L) of calcium carbonate (CaCO3). Hard water can cause scaling issues in plumbing systems and affect the efficiency of cleaning processes. CD BioSciences offers precise testing of water hardness, enabling clients to take appropriate measures for water treatment and management.
In addition to physical and chemical testing, CD BioSciences also offers microbial testing services to assess the presence of harmful bacteria, viruses, and other microorganisms in water. This comprehensive approach ensures a thorough evaluation of water quality, addressing both physical, chemical, and microbial aspects.
