FAQs

1. Why does the Analyzer eliminate chlorine interference?

Analyzer use anti-chlorine interference method. Anti-chlorine reagents do not interfere with measurements. They are formulated to neutralize only chlorine without reacting with organic compounds. Chlorine interference occurs when residual chlorine in water samples reacts during the analysis, leading to falsely elevated values. This is because chlorine is a strong oxidizer and can react with organic and inorganic substances during measurement. If chlorine is not neutralized, the Analyzer may overestimate the actual organic pollution, causing inaccurate water assessments, regulatory non-compliance and poor control in water treatment.

2. What is the purpose of the Analyzer?

Analyzer helps assess the organic load in water, which is critical for monitoring wastewater treatment efficiency, ensuring regulatory compliance and preventing environmental pollution. The Analyzer can detect different types of water samples including Industrial wastewater, municipal sewage, process water, surface and groundwater.

3. Which type safety precautions are required for handling the Analyzer?

Analyzer supports automatic measurements and provides direct concentration readings. Its built-in standard curve allows users to set up curves according to different measurement requirements. The Analyzer features a high-resolution touchscreen with a graphical user interface for easy operation but basic precaution measures such as wearing gloves and goggles when handling reagents, working in a well-ventilated area or fume hood, disposing of reagents according to local environmental regulations, is recommended for best results.

4. What are the features of the Analyzer ?

Analyzer offers a measuring range of 10 to 10 mg/L, a user-friendly interface, advanced cold light sources, narrow-band interference and microcomputer data processing to directly display the value of samples. The Analyzer offers batch processing of upto 20 samples per run. It also has a large data storage capacity of 1000 records supporting long-term monitoring and record-keeping and it also offers data retention even when power outages. Also features anti-chlorine interference for precise measurement range. It has separate water bath pot that allow the water bath method followed by colorimetric measurement. It offers colorimetric measurement for batch processing of up to 20 samples per run.

5. What ensures measurement accuracy of the Analyzer ?

The Analyzer utilizes advanced cold light and monochromatic light sources, ensuring exceptional optical stability without interference from various light sources. It provides optical stability with absorbance drift of ?0.002A/20min. Uses anti-chlorine interference method. Anti-chlorine reagents do not interfere with measurements. They are formulated to neutralize only chlorine without reacting with organic compounds. Chlorine interference occurs when residual chlorine in water samples reacts during the analysis, leading to falsely elevated values.
