    One more question, (FID)

    The FID detection limitation ( g/s) is : 2NW/A.

    N is the Baseline noise (A)
    W is the Mass of n-Hexadecane (g)
    A is the Average area amount of n-Hexadecane ( A• s)

    So, how to calculate the Baseline Noise (A)?

    (1) The Noise (N: peak to peak) is measure over a representative section of baseline equal to 20 times the width of the analyte peak ( Wi).

    (2) When the instrument is under optimal conditions that produce a continuous, electronic output, the Noise ( N ) may be measured from the Peak to Peak Variation ( N: peak to peak) in the baseline signal.

    N = N:peak to peak.
