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 device is commonly used in sample preparation for liquid, gas, and mass spectrometry applications, utilizing internationally recognized technology to ensure efficiency and precision. The nitrogen blowing instrument works by directing a stream of nitrogen over the surface of a heated sample, accelerating evaporation and concentration. It offers advantages such as time efficiency, ease of operation, and precise control, making it a popular choice across various industries.
This equipment is extensively applied in fields like agricultural residue analysis, commodity inspection, food safety, environmental monitoring, pharmaceuticals, and biotechnology. Its reliability and performance have made it an essential tool in laboratories worldwide.
When using a nitrogen blower, it's crucial to follow important safety precautions:
1. Avoid using the device with substances that have a flash point below 100°C.
2. Always wear appropriate protective gear, including gloves and eye protection.
3. Operate the nitrogen blower inside a fume hood to ensure proper ventilation.
4. Do not move the unit while it is heating to prevent burns.
5. Use a three-wire grounded power supply to avoid electrical hazards.
6. Never open the water bath casing when the device is powered on to prevent electric shocks.
7. Only trained professionals should perform maintenance or replace parts to avoid damage or safety risks.
8. Avoid using the instrument with highly flammable materials like petroleum ether.
9. Do not expose the device to acidic or alkaline substances, as they can cause internal corrosion.
For optimal performance and longevity, proper maintenance is essential:
- **Heating medium**: It is recommended to use distilled or deionized water to prevent scale buildup. Avoid using organic solvents as they may damage the system.
- **Algaecide**: When the unit is not in use, add a suitable algaecide to the water bath to prevent biological growth. Ensure the algaecide is neutral and does not interfere with your samples.
- **Water replacement**: Change the water in the water bath every one to two weeks, at most once a month, to maintain cleanliness and performance.
- **Acidic exposure**: If the instrument comes into contact with acidic substances, rinse it immediately with water after neutralizing with a mild sodium bicarbonate solution. Prolonged exposure to acids can cause irreversible damage, so always take necessary precautions if working with acidic materials.
