  • Hi elisjesu84,

    If you could supply a little more information we may be able to make some suggestions. Instrument model number and inlet type. Also the inlet flow parameters, column size and general methods settings will help. Sometimes this can be because you dont have enough total flow for the inlet for the mode you are operating in, for example, operating with low splits and a total flow of less that 20ml/min with a split/splitless inlet.
