Anadigi Solutions Private Limited

• Detects trace levels of organic carbon, including for ultrapure water used in semiconductor and pharmaceutical processes.

• Some models achieve very low detection limits, suitable for stringent specifications.

Shimadzu offers a full lineup to match different applications:

• TOC-L Series: Laboratory analyzers with high detection sensitivity using combustion catalytic oxidation — useful for pure water to heavily contaminated samples.

• TOC-4200: Online water quality analyzer designed for continuous monitoring across a broad range of sample types.

• eTOC Series (e.g., TOC-1000e S): Compact online analyzers for ultrapure water systems, featuring advanced sensitivity and lightweight design.

• Combustion catalytic oxidation method for thorough oxidation of organic compounds.

• UV or excimer lamp oxidation in compact models for mercury-free operation and lower maintenance.

• Optional software and communication interfaces (e.g., RS-485/RS-232) for enhanced data handling and instrument integration.

• Touchscreen displays and intuitive controls on many units simplify sampling and result interpretation.

• Some systems offer remote data viewing or USB export for easier reporting.

Shimadzu TOC analyzers are widely used for:

• Environmental water monitoring — rivers, lakes, groundwater, wastewater effluent.

• Drinking water quality control.

• Industrial process water monitoring, including cooling water and rinse water.

• Ultrapure water systems in semiconductor and pharmaceutical manufacturing.

• Regulatory compliance testing in laboratories (e.g., pharmaceutical water regulations). 

• Measurement Range: Typically 0.03 to 1.00 awa sub w𝑎𝑤 (0–100% ERH).
• Speed: Advanced models offer results within 4–5 minutes (e.g., $A_w$Quick function).
• Technology: High-precision probes, often using electrolytic or capacitive sensors, frequently with temperature control to ensure accuracy.
• Data Management: Many units allow for data storage (up to 10,000 records), USB data export, and RS232/485 interfaces.
• Applications: Essential for quality control in food (spoilage prevention), pharmaceuticals, chemical stability, and industrial materials (powders, tobacco). 

Precise Refractive Index Measurement
• Measures refractive index typically in the range of about nD 1.3000–1.7200 for most liquids and solids.

Brix (Concentration) Determination
• Many models also give %Brix values for sugar or dissolved solids — useful in food, beverage, chemical, and pharma labs.

 Automatic Temperature Compensation
• Built-in temperature sensing and compensation improves accuracy as refractive index varies with temperature.

Digital Display & Interfaces
• Results shown on an LCD/LED digital display for easy reading.
• Often includes RS-232 or USB interface for export to PC or printer.

 Hard Glass Prism & LED Illumination
• Durable optical prism for long life and stable measurements.
• LED or similar light source approximates the sodium D-line (~589 nm).

Digital Abbe Refractometers are widely used for:

• Chemical and petroleum quality control — checking refractive index for formulation or purity.

• Food & beverage industry — measuring sugar content (Brix) in juices, syrups, honey, etc.

• Pharmaceutical labs — ensuring solution concentrations and compliance.

• Educational & research institutions — teaching optics and material characterization.

Most digital Abbe refractometers come with:

• Main refractometer unit with digital display

• Standard calibration block and contact liquid

• Prism accessory/fixture for solids

• Interface cable (RS-232/USB)
