Common maintenance strategies for secondary thermal analyzer

The secondary thermal analyzer can automatically complete the desorption analysis process of 40 adsorption tubes. The instrument uses a unique two-stage thermal analysis structure, electronic refrigeration, two-stage low-temperature focusing real-time high-temperature analysis, high sensitivity. The good reproduction performance greatly improves the sample analysis rate and analysis efficiency, and effectively improves the resolution of chromatographic peaks.

The instrument uses semiconductor refrigeration, saving the cost of use. Electron refrigeration and a second-order thermal attachment process ensure a narrow chromatographic peak. The thermal analyzer needs maintenance after a period of use to ensure the normal operation of its later work and extend its service life.

secondary thermal analyzer maintenance:

1. Operators should receive relevant training and read relevant technical data in detail.

2. Replace the vulnerable parts of the secondary thermal analyzer regularly.

3. Regular maintenance of electrical equipment.

4. Power supply, sensor, touch screen, etc. Power supply. Sensors. The touch screen should be insulated. Anti-rat. Control temperature. Reduce damage to components due to oxidation, aging, leakage, short circuit and open circuit.

5. The knife edges, scales, and indicators on various measuring instruments should be protected from damage, kept clean, and regularly requested the measurement department to calibrate.

6. Due to wear, corrosion, dust, oil, fracture, damage, falling into foreign objects, looseness or improper operation of the mechanical system, the secondary thermal analyzer will die, slip, vibrate and run out of sync. The screw cannot be adjusted, and the sound temperature is abnormal. It can be investigated by watching, listening, measuring, touching, etc.

7. If an electrical failure occurs, the indicator light does not light up. If the display does not display or the data display is abnormal, you can measure the resistance, voltage, and current signals to check whether the switch, fuse, filament, wire, and electrical components are leaking or in poor contact, and replace the original device in question.
