Nitrogen blower water separation bath, metal bath, is an instrument for preparing concentrated samples in liquid phase, gas phase and mass spectrometry experiments. It mainly blows nitrogen into the surface of heated samples for sample concentration, which is time-saving and convenient. Easy to control, widely used in pesticide residue analysis, commodity inspection, food, environmental, pharmaceutical, biological products and other industries.
The following is a brief description of several things that should be noted during the testing of the nitrogen blower.
First, when using a water bath nitrogen blower, do a good job of hand and face protection
During the heating process of the sample, the hot water in the waterproof bath is splashed out, and the hands and eyes are burned. The hand and face protection work must be done before the operation, wearing gloves and eye masks.
Second, ensure good ventilation
In order to prevent some vapors, gases and particulates (smoke, soot, dust and aerosols) from being loaded into the instrument during operation, the accuracy of the experiment is affected. It is necessary to operate the fume hood, ventilating hood or local ventilation to remove pollutants. Remove.
Third, do not move nitrogen blower
Do not move the nitrogen blowing instrument during the test. The experimental instrument is heated at a high temperature to prevent burns.
Fourth, the use of three-wire grounding power supply
The nitrogen blower has a large power, and it is necessary to use a three-wire grounding power source to ensure safe use of electricity.
Five, do not bring electricity to open the water bath shell
During the experiment, the instrument is energized to cause leakage and electric shock accidents under the condition of the material in the waterproof bath. Do not open the water bath casing with electricity.
6. Prohibit non-professional maintenance instruments
The maintenance of the nitrogen blower should be carried out by professionals. Due to the extremely complicated internal structure, improper replacement of components may cause damage to the nitrogen blower or
