Pressure Above Upper Limit

1

Upper pressure limit set too low.

Ensure the upper pressure limit is set to a value suitable for the analysis.

2

Blockage in the flowpath (after the damper).

Check for blockage in the flow path. The following components are particularly subject to blockage: inline filter frit, needle (autosampler), seat capillary (autosampler), sample loop (autosampler), column frits and capillaries with small internal diameters (e.g. 50 µm ID).

3

Blockage in the flowpath (after the pressure sensor).

Check for blockage in the flow path. The following components are particularly subject to blockage: inline filter frit, needle (autosampler), seat capillary (autosampler), sample loop (autosampler), column frits and capillaries with small internal diameters (e.g. 50 µm ID).
