Common faults and solutions of Kjeldahl nitrogen analyzer

Nitrogen analyzer is an instrument for measuring the content of nitrogen and protein in samples. Kjeldahl nitrogen analyzer calculates the protein content by measuring the nitrogen content in the sample according to the principle that the nitrogen content in the protein is constant. The universal applicability, accuracy and repeatability of Kjeldahl method have been widely recognized, and has been established as a standard method for detecting protein content in food.

Common faults and solutions of Kjeldahl nitrogen analyzer:

Faults

Causes

Troubleshooting

The instrument cannot be powered on

The power cord is not properly plugged and the fuse is blown

Plug in the power cord and replace the fuse

Cannot add alkali

There is too little alkali in the alkali liquor bucket, the alkali liquor inlet pipe leaks, sodium hydroxide is separated, and the pipeline is blocked

Add reagent to the alkali liquor bucket to check whether the pipeline interface is sealed, and clean the pipeline

Cannot add acid

There is too little acid in the acid liquor bucket, and the acid inlet pipe leaks

Add reagent to the acid bucket   to check whether the pipeline interface is sealed

Digestive tube cannot be discharged

The waste pipe is blocked, the waste pipe of digestion pipe leaks, and the waste pipe orifice is higher than the instrument

Clean the waste pipe, replace the waste pipe, and place the waste pipe orifice below the instrument

Condensate water cannot enter the condensate pipe

The pressure of condensate water is not enough

Increase water pressure or add water with pump

Condensate water does not circulate

The pressure of condensate water is not enough, and the water outlet is higher than the water inlet

Increase the water pressure or use a pump to add water  and place the water outlet lower than the water inlet

The distilling cup cannot be filled with water

Insufficient water inlet pressure

Increase water pressure or add water with pump

The distilling cup cannot be drained

The water outlet is higher than the water inlet, and the drain pipe valve is blocked

Put the water outlet lower than the water inlet and clean or replace the drain valve
