Gelex

Understanding Gelex: A Key Player in Environmental & Water Treatment

In the world of environmental and water treatment, turbidity is a crucial parameter to monitor. It measures the cloudiness or haziness of a liquid, indicating the presence of suspended particles that can impact water quality and treatment efficiency. To accurately measure turbidity, we rely on instruments called turbidimeters.

One critical aspect of ensuring reliable turbidity readings is the use of a standardized calibration suspension, often referred to as Gelex. Gelex, a suspension of formazin polymer, serves as the primary reference material for calibrating turbidimeters.

Why is Gelex so important?

• Consistency: Gelex provides a consistent and reproducible reference material, ensuring that different turbidimeters generate comparable readings.
• Accuracy: Properly calibrated turbidimeters using Gelex deliver accurate turbidity measurements, critical for monitoring water quality and treatment processes.
• Standardization: Gelex is recognized as the global standard for calibrating turbidimeters, fostering uniformity and comparability in turbidity measurements across industries and geographies.

Hach Company: Leaders in Turbidimeter Standardization

Hach Company, a leading provider of water analysis solutions, plays a pivotal role in standardizing turbidimeters and Gelex. Their commitment to accuracy and reliability is evident in their rigorous standards and processes:

• Production of High-Quality Gelex: Hach manufactures Gelex in accordance with strict quality control measures, ensuring consistent composition and stability.
• Standardized Procedures: Hach provides detailed procedures for preparing and using Gelex, ensuring consistent calibration and accurate results.
• Certified Standards: Hach offers certified Gelex standards with traceable reference values, allowing for accurate calibration and verification of turbidimeters.

The Role of Standards in Turbidimeter Calibration

Hach's standards play a crucial role in the calibration of turbidimeters:

• Primary Standards: These are highly accurate and traceable standards that define the turbidity unit (NTU). Hach's certified Gelex standards fall under this category.
• Secondary Standards: These are typically prepared from primary standards and used for routine calibration of turbidimeters.
• Working Standards: These are diluted from secondary standards and used for daily checks and adjustments of turbidimeters.

By adhering to these standards, Hach ensures accurate and reliable turbidity measurements, critical for a wide range of applications, including:

• Drinking Water Treatment: Monitoring turbidity in drinking water ensures the safety and quality of water for consumption.
• Wastewater Treatment: Monitoring turbidity in wastewater helps to determine the effectiveness of treatment processes.
• Industrial Processes: Turbidity monitoring is crucial in industrial processes involving water, such as chemical manufacturing and food production.

Conclusion

Gelex and Hach's commitment to standardization are essential for reliable turbidity measurements. By ensuring accurate and consistent calibrations, we can effectively monitor water quality and optimize treatment processes. This plays a critical role in protecting public health and the environment.
