Authorized Analytik Jena Distributor · Nepal
Analytik Jena TOC Analyzer.
Catalytic combustion. NDIR detection. Audit-ready total organic carbon.
The multi N/C series — automated high-temperature combustion TOC for pharmaceutical water, environmental compliance, and industrial process samples. Pharmacopoeia methods supported.
The Analytik Jena multi N/C series measures total organic contamination in water — injecting a micro-volume sample into a high-temperature combustion tube packed with a platinum catalyst, oxidising all organic matter to CO₂, and quantifying the result via a high-sensitivity NDIR detector. Results report in milligrams of organic carbon per litre, documented and audit-ready, with method support for USP <643>, EP 2.2.44, and JP XVI compliance. JHS Analytic Traders is Analytik Jena's authorized distributor in Nepal.
Catalytic high-temperature combustion
Oxidises all organic compounds — including humic acids, polymers, and particulate-bound organics that UV-persulphate methods routinely under-recover.
NDIR carbon, optional nitrogen channel
High-sensitivity NDIR detection for carbon. An optional chemiluminescence channel measures total bound nitrogen in parallel from the same injection.
Pharmacopoeia method-ready
Methods supported for USP <643>, EP 2.2.44, and JP XVI. Audit-trail-capable software for GMP-regulated environments.
Six Parameters from One Sample Injection
The multi N/C reports each parameter individually — helping you pinpoint whether contamination is organic or inorganic, dissolved or particulate. TNb measurement (total bound nitrogen) runs simultaneously with TOC when equipped with the chemiluminescence detector, eliminating the need for a separate Kjeldahl analysis.
A combustion lab in a single chassis
Inside the multi N/C: sample is acidified and sparged to remove inorganic carbon, then injected into a high-temperature combustion tube where a platinum catalyst drives complete oxidation. The CO₂ stream is dried, scrubbed of halides, and quantified by a high-sensitivity NDIR detector. An optional chemiluminescence channel measures total bound nitrogen in parallel — six parameters from a single injection.
Where TOC Analysis Is Required
Pharmaceutical Water Systems
Purified Water and WFI monitoring per USP <643> and EP 2.2.44. Validates that production water meets organic purity limits required by DDA and international GMP.
Drinking & Environmental Water
Rivers, groundwater, drinking water treatment plants, and factory discharge monitoring. Confirms organic contamination is within regulatory limits.
CIP Rinse Validation
After cleaning tanks, vessels, and piping in food, beverage, or pharmaceutical production — confirms no organic residue remains before the next batch.
Food & Beverage QC
Process water purity verification, rinse-water validation after sanitation, and incoming water quality checks for production.
TOC Testing in Nepal's Growing Pharma Sector
Nepal's pharmaceutical manufacturers — producing for the domestic market under DDA GMP and for export under WHO-PQ and PIC/S guidelines — require validated TOC monitoring on purified water and WFI systems, where USP <643> TOC testing is a regulatory requirement. JHS supplies the multi N/C series with installation, operator training, method validation support, and consumable supply — scope confirmed per project at quotation.

TOC Analyzers in Nepal
What does a TOC Analyzer actually do?
It measures how much organic material is dissolved or suspended in your water sample. The Analytik Jena multi N/C injects the sample into a high-temperature combustion tube — this converts all organic material into CO₂ gas, which is precisely measured by an NDIR detector. The result tells you the concentration of organic carbon in milligrams per litre, without the wet chemistry and multi-day incubation that traditional methods require.
Which businesses in Nepal need a TOC Analyzer?
Pharmaceutical manufacturers (purified water and WFI monitoring per USP <643> is mandatory for GMP compliance), environmental and water quality testing labs, drinking water treatment plants, food and beverage factories validating CIP rinse water, and power plants or semiconductor facilities monitoring boiler feed or ultrapure water.
How is a TOC test different from BOD or COD?
TOC gives results rapidly via direct combustion oxidation. BOD takes five days (measures oxygen consumed by microbes). COD uses chemical oxidation with dichromate. TOC is faster, more reproducible, generates less hazardous waste, and is the method required by pharmacopoeias for pharmaceutical water testing. For routine daily quality control, TOC is the standard.
What oxidation methods do TOC analyzers use?
Two main approaches: (1) Catalytic high-temperature combustion (HTC) — the method used by the Analytik Jena multi N/C. Oxidises all organics including difficult compounds. (2) UV-persulphate — lower-temperature wet oxidation. Simpler but can under-recover certain high-molecular-weight or particulate-bound organics. HTC is preferred for labs needing a single robust platform across sample types.
Does the multi N/C meet pharmaceutical compliance requirements?
Yes. The multi N/C series meets USP <643>, EP 2.2.44, and JP XVI requirements for TOC testing of pharmaceutical water. The software supports FDA 21 CFR Part 11 electronic records and signatures, audit trails, and user access controls required in GMP-regulated environments. System suitability testing (SST) with sucrose/1,4-benzoquinone is automated.
Does JHS provide installation, training, and service?
Yes. As Analytik Jena's authorized distributor in Nepal, JHS Analytic Traders provides installation, IQ/OQ documentation, operator training, method validation support, consumable supply (catalysts, NDIR cells, tubing), preventive maintenance, and technical support. Specific scope and warranty terms are confirmed per project at the quotation stage.
