Background technology
Kjeldahl's method is a kind of method for determining nitrogen pool in compound or mixture.There is the condition of catalyst
Under, organic nitrogen is all transformed into inorganic ammonium salt with concentrated sulfuric acid sample digestion, ammonium salt is then converted into ammonia in the basic conditions, with
Steam distillation out and for excessive borate absorbs, then with standard HCI, so that it may calculate the nitrogen quantity in sample.By
It is more constant in protein nitrogen content, protein content can be calculated by its nitrogen quantity, so method is classical protein quantitation methods.
At present, triumphant formula nitriding mainly needs to carry out the operation such as distilling using triumphant formula azotometer, but the device, and in biology
It is extremely dangerous using naked light in experiment, and the experimental gas are more, it is necessary to sealing very high.
The content of the invention

Using naked light, can add water at any time without stopping reacting, security performance is high, the distillation reaction of the more stable Kjeldahl's method of reaction
Device.
To reach above-mentioned purpose, the technical solution adopted in the utility model is as follows：
A kind of distillation reaction device of Kjeldahl's method, including steam generator, sample inlet, reaction tube, condenser pipe and
Absorption bottle, steam generator is connected with sample inlet, and sample inlet is connected into reaction tube by conduit, and the conduit that reaction tube stretches out leads to
Cross condenser pipe and enter absorption bottle, also including water inlet pipe, water tank and oil bath pan, the steam generator lower end is oil bath pan, is steamed
Vapour generator is connected by water inlet pipe with water tank.
Preferably, it is provided with water intaking valve on the water inlet pipe.
Preferably, it is provided with gas-liquid separator between the steam generator and sample inlet.
Preferably, all coupling parts are sealed with sealing shroud in described device.
In sum, by adopting the above-described technical solution, the beneficial effects of the utility model are：
