Spike/ Interference on Beckman P800 Plus CE

Could anyone shed any light on some crazy interference with the Beckman 800 Plus instruments.

During a run the first few injections could be perfect and then there is so much noise in the e-grams that the IgG peaks are barley distinguishable from the interference peaks/spikes.

The capillary is fine and the lamp is new.

Is there a facility to upload e-grams on this forum.

Any help much appreciated
