Approved official analytical method for foods, feeds and fertilizers SUMIGRAPH NC-TRINITY
SUMIGRAPH NC-TRINITY is a total nitrogen and total carbon analyzer for samples with poor homogeneity, such as foods, feeds, fertilizers, plants, and soils.
Since a large portion of sample can be provided for analysis, SUMIGRAPH NC-TRINITY can be used for agricultural environment studies as well as for crude protein in food or feed (Food Labeling Act, Act on Standardization and Proper Quality Labeling of Agricultural and Forestry Products (so-called JAS Act), and Feed Analysis Standards).
The measurable amount of sample is 2 g for soils and about 1 g for organic substances (e.g., food), minimizing the effect of sample inhomogeneity.
The adopted assay method is safer than the conventional Kjeldahl method and Tyurin’s method, free from concerns about contamination of work environment and surrounding areas. Additionally, nitrogen and carbon can be measured simultaneously simply by switching the measurement time.
Features of SUMIGRAPH NC-TRINITY
NC-TRINITY Full-automation type
Equipped with automated sampler by default to which 48 samples can be set. Continuous automated assay starts simply by setting a boat with weighed sample to the automated sampler and pressing the start button.
Approved official analytical method (please ask us for details)
Complies with protein assay in the Food Labeling Act (quantitative conversion method)
Complies with total nitrogen assay in the Japanese Agricultural Standards (JAS Act) and the Feed Analysis Standards
Complies with the Japanese Industrial Standards (JIS Act) and the NBR Analysis
High sensitivity and broad assay range
High accuracy assay can be made for a broad range. [Nitrogen: 0.003-100% (0.03-200 mg), carbon: 0.001-100% (0.01-500 mg)]
Simple sampling and weighing
Sampling is extremely simple and easy; you just place the sample on the boat – no need to mix with combustion improver or to seal it. Additionally, the boat can be used repeatedly, contributing to reducing the running cost.
Since a large portion of sample is used for reaction, an adequate assay accuracy can be achieved by weighing using scales with a reciprocal sensitivity of 0.1 mg (1 or 0.01 mg depending on the sample).
Minimal maintenance, effective analysis
The reduced copper and moisture absorbent can be used for 600-800 times and 2000-3000 times successive measurements, respectively, and combustion residues are automatically collected. The time required to stop the apparatus for maintenance can be reduced, realizing a high rate of operation.
The circulation system piping is unitized and controls are consolidated into one board. With these, maintainability has been improved.
Further, SUMIGRAPH NC-TRINITY uses a dry combustion method. Free from liquid waste, it can be used efficiently and economically by cutting the labor and cost involved with treatment of liquid waste.
SUMIGRAPH NC-TRINITY is a clean assay system with minimal environmental contamination.
SUMIGRAPH NC-TRINITY does not generate phosphate mist like the Kjeldahl method does. Since there is no need to worry about contamination of work environment and surrounding areas, it can be used without installing incidental equipment such as fume hoods or scrubbers.
Consumption of reduced copper and absorbents is minor, helping in minimizing generation of waste.
Apparatus width and weight were downsized to about 2/3 of conventional models. Through various technology innovations, about 30% of downsizing has been successfully realized.
