Be sure that the TCD current is not over the value on the following chart below.
Detector sensitivity is improved when the TCD current is increased (sensitivity is proportional to the cube of the TCD current). However, the durability of detector filament is shortened when the TCD current is large value. Therefore, the TCD current should not be increased when the detector sensitivity is enough value.
The durability of detector filament is shortened by the strong acid or corrosive gas etc.
