TOC/TNb Analysis Service

Total organic carbon (TOC) and total nitrogen bound (TNb) are critical metrics for assessing organic load and nitrogen content across diverse sample types. Widely applied in environmental science, food safety, pharmaceutical quality assurance, and bioprocess monitoring, TOC quantifies the overall organic content, while TNb encompasses all forms of nitrogen—including ammonium, nitrate, nitrite, and organically bound nitrogen—offering a complete view of nitrogen distribution.

 

The TOC/TNb Analysis Service utilizes a total-content quantification approach that enables rapid evaluation of organic and nitrogen loads without the need to identify or quantify individual components. Compared to conventional compound-specific methods, this approach is more time-efficient and cost-effective, especially for complex or compositionally unknown matrices. TOC/TNb Analysis Service plays a pivotal role in environmental risk management, wastewater compliance, food and bioculture system optimization, and industrial process control.

 

Leveraging a high-performance elemental analysis platform and validated SOPs, MtoZ Biolabs provides accurate and scalable TOC/TNb Analysis Service solutions for both liquid and solid samples across a wide range of industries and scientific applications.

 

Services at MtoZ Biolabs

MtoZ Biolabs offers comprehensive TOC/TNb Analysis Service powered by high-temperature catalytic combustion, non-dispersive infrared detection (NDIR), and ultraviolet oxidation combined with chemiluminescence detection (CLD). Our platform supports:

1. TOC measurement, including total carbon (TC), inorganic carbon (TIC), and differentiated TOC analysis, for samples such as drinking water, surface water, wastewater, soil, and sediment.

2. TNb quantification, enabling complete nitrogen profiling across nitrate, nitrite, ammonium, and organic nitrogen forms.

3. Advanced parameters, including NPOC (non-purgeable organic carbon), DOC (dissolved organic carbon), POC (particulate organic carbon), and DNb (dissolved nitrogen bound), available upon request.

 

Service Advantages

Our TOC/TNb Analysis Service from MtoZ Biolabs is engineered for flexibility and analytical precision, with the following key advantages:

✔ Diverse oxidation options: Supports both UV wet oxidation and catalytic combustion tailored to sample matrix characteristics.

✔ Automated and modular sample processing: Accommodates varied viscosities, salinities, and compositions through flow injection and direct injection modes.

✔ Multi-channel detection: CO₂ is quantified via NDIR for TOC, while NO is measured via CLD for TNb, enhancing dual-parameter detection accuracy.

✔ Cost- and time-effective: Enables integrated evaluation of organic and nitrogen content, avoiding time-consuming, compound-specific testing.

✔ Customizable workflows: Supports method development for academic research, regulatory submission, and industrial quality assurance.

✔ One-time-charge: Our pricing is transparent, no hidden fees or additional costs.

 

Applications

Our TOC/TNb Analysis Service provides precise carbon and nitrogen metrics across diverse disciplines:

· Environmental monitoring and risk assessment: Determine organic pollution and nitrogen load in surface water, groundwater, seawater, and industrial effluents.

· Pharmaceutical and clinical water validation: Ensure the quality of purified water, WFI (water for injection), and validate cleaning processes.

· Food and agricultural system optimization: Evaluate irrigation water, soil fertility, and organic content in agricultural runoff or sediments.

· Energy and chemical manufacturing: Monitor precursor quality in lithium battery materials, catalysts, phosphates, and hydrogen peroxide.

· Mining and metallurgy: Analyze carbon load in oil shale, ores, and industrial byproducts prior to processing.

 



 

FAQ

Q1: What types of samples are compatible with TOC/TNb analysis?

Our TOC/TNb Analysis Service is compatible with both liquid and solid matrices, including drinking water, wastewater, soil, sediment, and industrial byproducts. MtoZ Biolabs provides matrix-optimized protocols to ensure high reproducibility and data quality.

 

Q2: Can TOC and TNb be measured simultaneously?

Yes. Our instruments allow for simultaneous TOC and TNb detection within a single run, combining oxidation, gas detection, and data output—ideal for high-throughput and rapid screening workflows.

 

Q3: How are high-salt or particulate-rich samples handled?

High-matrix samples are addressed through sample dilution, filtration, and the use of corrosion-resistant systems. Our pre-conditioning steps and robust combustion methods ensure stability and data accuracy, even under challenging conditions.
