  8  Maintenance and Troubleshooting 

8.1  Maintenance of the Instrument 

Proper maintenance will not only help the instrument work normally but also prolong its life. Pay attention to the 
following four points during the maintenance: 
1)

 

The instrument can only work under the required conditions. Take some corrective measures when certain 
required conditions are not met. 

2)

 

The operation must strictly abide by the operating regulations. Prevent oil, organic matter and other substances 
from contaminating the detector and the tube. Otherwise the tube will be blocked or the performance of the 
instrument will be degraded. 

3)

 

The column temperature should be no higher than the recommended temperature range in the stationary phase. 
Generally, the column temperature is lower than the recommended temperature range in the stationary phase. 
When the high sensitivity operation is going on, the column temperature should be set lower.   

    When the carrier gas is transmitted into 

INE-112N-GC

, the pressure should be set at 343000Pa (equivalent to
