Agilent second-hand liquid phaseDuring use, you may encounter various error situations. Here are some common errors and their quick handling methods:

　　1、 Degassing machine error

Reason for error:

1. Insufficient vacuum degree.

2. Circuit board malfunction.

Handling method:

1. Check if there is any air leakage in the pipelines and interfaces of various components, and reconnect them. Check if there is any liquid flowing out of the pipeline, confirm and reconnect the infusion pipeline interface.

2. Connect the vacuum pump suction port directly to the sensor and observe whether the pump keeps running and stopping. If running continuously or starting frequently, check whether the pump sealing components are dirty or damaged. If everything is normal, connect the vacuum pack again for testing.

3. If the circuit board malfunctions, consider replacing it.

　　2、 Pump part error

Reason for error:

1. The PURGE valve filter element is dirty and affects the system pressure.

2. Pump head blockage or active valve malfunction.

3. Pump drive failure.

Handling method:

1. Clean the PURGE valve filter element.

2. Disassemble the pump head to check for salt precipitation or other impurities, and clean it. If the pump head is rough or the active valve malfunctions, corresponding maintenance or replacement is required.

If the pump drive fails, the pump drive needs to be replaced.

　　3、 Automatic sampler error

Reason for error:

1. The sensor magnet on the door is missing.

2. The robotic arm is stuck or there is a transmission failure.

3. Mainboard or firmware malfunction.

Handling method:

1. Ensure that there is a magnet on the door of the automatic sampler. If not, place the magnet in the corresponding position.

2. Check if the robotic arm is stuck or if there is a transmission fault, and perform corresponding repairs.

If the motherboard or firmware fails, it is necessary to replace the motherboard or flash the firmware again.

　　4、 Detector error

Reason for error:

1. The type of circulation pool is incorrect or dirty.

2. The wrong port of the network card caused it to burn out.

3. Deuterium lamp or motherboard malfunction.

Handling method:

1. Confirm whether the type of circulation pool is correct and clean the dirt.

2. When connecting the network card, pay attention to distinguishing between the LAN port and the CAN port to avoid damage caused by incorrect insertion.

3. Replace the deuterium lamp and check if the motherboard is faulty. If there is a fault, replace the motherboard.

　　5、 Other errors reported

Reason for error:

1. Column temperature control failure.

2. CAN port connection issue.

3. Leakage causes sensor malfunction.

Handling method:

1. Check if the temperature control of the column temperature box is normal, and carry out corresponding maintenance or replacement.

2. If one port cannot be connected when connecting the CAN port line, try changing to another port connection.

3. Check for any leakage, clean up the leakage, and check if the sensor is faulty. If there is a fault, replace the sensor.

The common errors in Agilent's second-hand liquid phase involve multiple components and systems, and quick solutions require targeted repairs or replacements based on the specific cause of the error. During use, it is recommended to regularly maintain and inspect the equipment, promptly identify and address potential issues, to ensure the normal operation of the equipment and the accuracy of experimental results.
