Dear Dr. Sanghamitra,

Please 1) wash the sampler and skimer cones; 2) change the tubes of peristaltic pump and auto-sampler; 3) leave ICP-MS under high vacuum over night.

wish you all the best

Sanghamitra Katragadda

Thank you for your response. I had changed the cones and the tubes, but still the problem arises. Tried all the possibilities I know . But not getting the results.

Jie Lin

all the elements' background are high? or several elements? The gas flow rate or the voltages of lens may be not suitble when the background is ver high, especially when all the cones and tubes are alrealy clean.
