The Kjeldahl method is one of the most accurate methods for determining nitrogen and protein in a wide group of products, but, unfortunately, it has a number of significant drawbacks - these are low speed, a large number of possible losses during the analysis, bulky equipment, and the use of aggressive reagents. Sibagropribor Holding presents KELTRUN (KELTRUN) - a set of equipment for carrying out a complete analytical cycle according to the Kjeldahl method, which will allow: • to increase the speed of analyzes (high speed of distillation and ashing, simultaneous processing of several samples); • ensure the safety of personnel (high quality of reaction vessels, effective absorption of acid vapors by the exhaust system, additional protection of personnel in emergency situations); • reduce possible losses in the analysis process; • improve the reproducibility of results. «KELTRAN» (KELTRUN) will allow you to determine nitrogen / protein in the widest list of substances: • food products: dairy, cereals, meat, cereals, etc.; • feed and compound feed; • fertilizers; • water, drinks, beer; • soil, bottom sediments, sediment samples, activated sludge; • crude oil, lubricants; • various chemicals; • alcohol content in wines, musts and spirits; • etc. The set of equipment «KELTRAN» (KELTRUN) allows you to analyze according to GOST and determine the nitrogen content in the range of 0.02 - 99.00%. Composition of the complex «KELTRAN» (KELTRUN): - Digestor; - Distiller; - Scrubber (*not included in the price of the complex); - Titration unit: manual, semi-automatic or automatic (*not included in the price of the complex); Warranty - 1 year. Important feature! In many distillers (made in China and others), when used, alkali passes through a valve-type pump, with a low production resource (sometimes the resource is enough for only 3 months). In the distiller of our production, the alkali passes through a RELIABLE PERISTALTIC PUMP, this ensures a long service life of the distiller!

It can be used as a primary source of carrier gas, since it is equipped with an additional gas purification system. This device is especially relevant when, for some reason, helium is not available to the consumer (for example, when working with a thermal conductivity detector - an accident). Due to the high thermal conductivity of hydrogen, TTP operates with significantly greater sensitivity than helium.

To analyze small concentrations of carbon monoxide (CO) and carbon dioxide (CO2), instead of the usual catarometer for these gases, a more sensitive PID is used, while carbon oxides are converted into methane (CH4) using reaction chromatography. The device implementing the conversion reaction is called a methanator, i.e. a device with a special catalyst that converts CO, CO2 into methane in a hydrogen current, while the latter is either a carrier gas itself, or is blown together with the carrier gas into the methanator through a tee. The methanator provides a highly efficient conversion reaction, while the detection limit of carbon oxides reaches 0.1 ppm. technical specifications Metanation temperature — 330 °C The coefficient of metanation is not less than 95 % The effective volume of the methanator is 1 ml.

To determine small concentrations of substances, in some cases it is impossible to do without their concentration in special traps. An example of the need for such concentration is the determination of impurities in permanent gases (Ne, He, H2, Ar, O2, N2, Kr, Xe), the concentration of impurities is less than 1 ppm. Considering that these impurities can be not only hydrocarbons, but also permanent gases themselves, the use of direct detection of impurities by a catarometer is impossible. It is also not always possible to use highly sensitive but expensive detectors (GID, EDD, etc.). TECHNICAL CHARACTERISTICS The volume of the trap is 5 ml. The volume of the Dewar vessel (serial metal thermos) is 1200 ml. The concentration temperature range is from minus 88.6 (ethane) to minus 269 °C (helium).
