01 / POTABLE & GROUNDWATER
Drinking & Borewell Water
Evaluation against IS 10500 standards (acceptable limit 250 mg/L; permissible limit 1,000 mg/L in absence of alternate source) to assess palatability and mineral balance.
Services / Chloride Testing Services
Chloride Testing Services
Accurate determination of inorganic and total chloride across potable water, process streams, industrial effluent, and environmental water bodies.
Analytical Precision
Comprehensive Chloride Determination Across Water & Industrial Matrices
Chloride (Cl⁻) is one of the most critical anions monitored in environmental science, municipal utilities, and industrial utilities. High chloride concentrations can accelerate metallic corrosion in boilers and cooling towers, impart a salty taste to drinking water, impair soil health during irrigation, and indicate industrial pollution or saltwater intrusion.
Sishodia Research Laboratories Private Limited (SRLPL) performs chloride analysis across raw water, process water, boiler feed, construction batching water, and treated trade effluents using standard test methods including Argentometric titration and Mercuric Nitrate titrimetric techniques.
Sample Matrices
Supported Sample Types & Applications
We test chloride content across a broad spectrum of liquid and wastewater matrices tailored to statutory standards and industrial benchmarks.
02 / INDUSTRIAL EFFLUENTS
Wastewater & Trade Effluents
Testing untreated and treated effluent streams from chemical, textile, food processing, and distillery units to verify consent compliance before discharge or recycling.
03 / UTILITIES & BOILERS
Boiler Feed & Cooling Towers
Monitoring low-level chloride in make-up and condensate streams to prevent pitting corrosion, stress corrosion cracking (SCC), and scale formation in heat exchangers.
04 / CONSTRUCTION WATER
Concrete Batching Water
Testing construction water as per IS 456 / IS 3025 requirements (maximum 2,000 mg/L for plain concrete; maximum 500 mg/L for reinforced concrete) to protect rebar integrity.
Approved Methodologies
Technically Validated Test Methods
Analytical determinations follow nationally and internationally recognised standard testing protocols.
Argentometric Method (Mohr's Titration)
Direct titration with standardized silver nitrate (AgNO₃) solution using potassium chromate indicator in neutral or slightly alkaline conditions (pH 7.0–10.0). Ideal for clear potable and surface water samples with chloride concentrations above 5 mg/L.
Standard Reference: IS 3025 (Part 32) / APHA 4500-Cl⁻ B.
Mercuric Nitrate Method
Titration using mercuric nitrate with diphenylcarbazone-bromophenol blue mixed indicator under strictly controlled acidic pH (2.3–2.8). Well-suited for low-level chloride determinations and colored or turbid wastewater samples.
Standard Reference: APHA 4500-Cl⁻ C.
Potentiometric / Instrumental Titration
Utilizing silver/silver chloride ion-selective electrodes for automated end-point detection in heavily colored or opaque industrial waste samples where visual color change cannot be observed reliably.
Standard Reference: APHA 4500-Cl⁻ D.
Sample Protocols
Sample Collection & Handling Guidance
Accurate laboratory quantification begins with proper representative sampling on site. Follow these practical recommendations when collecting and dispatching samples:
- Sample Container: Collect samples in clean, high-density polyethylene (HDPE) or borosilicate glass bottles. Rinse the container 2–3 times with the water being sampled prior to collection.
- Required Minimum Volume: 500 mL for standalone chloride analysis; 1 to 2 Litres if full physical-chemical water profiling is required.
- Chemical Preservation: No special chemical preservation is needed for chloride testing. Avoid adding acid fixatives unless specified for concurrent heavy metal analysis.
- Storage & Transit: Keep samples refrigerated or packed in insulated ice boxes at 4°C during transportation. While chloride is stable, submit samples within 7 days of collection.
What Information Is Needed for a Quotation?
To receive an accurate and competitive test estimate, please let us know:
- Sample Matrix: (e.g. Borewell water, boiler blowdown, treated STP effluent).
- Number of Samples: Single test vs. recurring monthly / quarterly monitoring program.
- Concurrent Parameters: Chloride only, or comprehensive suite (pH, TDS, Hardness, Sulphate, Alkalinity, Heavy Metals).
- Reporting Turnaround: Standard (3–5 working days) or Express testing requirement.
