The study provides new function tested on labetalol in large infusion volumes (V inf  = 80-115 µL)  via  electrospray ionization mass spectrometry, tandem MS 2 –MS 7  operation modes and collision energy: 0, 0.1, 10, 20, 25, 26, 30 and 35 eV, respectively. It is derived from the  stochastic dynamic mass spectrometric  equation D” SD  = 2.6388.10 -17 .(&lt;I 2 &gt;-&lt;I&gt; 2 ), which exactly quantifies analyte concentration in solution. Also, it determines 3D conformations and electronic structures. The description of mass spectrometric intensity data as random variables and the shown relation, there are written two new linear functions among D” SD  parameters, average total intensity values of fragmentation peaks, infusion volume, and collision energy. They introduce  covariance  of datasets of variables  per  short span of scan time of ions in any experimental conditions “l” and “m”. They are: D” SD;m,l  = D” SD,l  + D” SD,m  + 5.2776.10 -17 .{&lt;I l .I m &gt;–&lt;I l &gt;.&lt;I m &gt;}≈&lt;I l &gt;+&lt;I m &gt; and &lt;I l &gt;+&lt;I m &gt;≈|r l,m |.sd(yEr±) 1 .sd(yEr±) m . Those relations yields to new formula D” SD,l + D” SD,m  = |r l,m |.sd(yEr±) l .sd(yEr±) m , providing exact function of mass spectrometric variable  intensity  of any peaks of analyte ion in any two sets of experimental conditions of measurements and diffusion parameters according to the first formula. Correlation between theory and experiment of fragmentation processes of labetalol shows |r|=1–0..  Chemometrics  is used.
