The Shanghai Xingzhuang Nitrogen Drying Instrument, also known as the Termovap Sample Concentrator, is widely referred to as a nitrogen concentrator, nitrogen purifier, or nitrogen blower. This advanced device is commonly used in sample preparation for liquid, gas, and mass spectrometry applications, utilizing internationally recognized technology to ensure accuracy and efficiency. The nitrogen blowing instrument works by directing a stream of nitrogen gas over the surface of a heated sample, effectively evaporating solvents and concentrating the sample. This method offers significant advantages, such as saving time, ease of operation, and precise control, making it an essential tool in various scientific fields.
It is extensively applied in agricultural residue analysis, commodity inspection, food safety testing, environmental monitoring, pharmaceutical development, and biotechnology industries. To ensure safe and effective use, users should follow specific precautions:
1. Avoid using the nitrogen blower with substances that have a flash point below 100°C.
2. Always protect your hands and eyes when operating the device.
3. Use the nitrogen blower within a fume hood to maintain proper ventilation.
4. Do not move the unit while it is heating to prevent burns.
5. Ensure the power supply is a three-wire grounded system.
6. Never open the water bath casing while the device is powered on to avoid electric shock.
7. Only trained professionals should perform maintenance to prevent damage or safety risks.
8. Do not use the nitrogen blower with highly flammable materials like petroleum ether.
9. Avoid contact with acidic or alkaline substances, as they can damage the equipment.
For optimal performance and longevity, regular maintenance is essential:
1. Use distilled or deionized water as the heating medium to prevent scale buildup. Avoid organic solvents.
2. Add an algaecide to the water bath when not in use to prevent biological contamination. Choose non-acidic algaecides that do not interfere with samples.
3. Replace the water in the bath at least once a week, and no later than one month.
4. If exposed to acidic substances, rinse the affected areas immediately with a mild sodium bicarbonate solution, followed by thorough water rinsing. Prolonged exposure to acids can cause corrosion and damage to the instrument.
