Nov 1, 2019 · where â s is the spacing between the apex of two signals with respect to their average baseline width, w av = (w 1 +w 2)/2.This equation is applicable to all signal shapes; however, the significance of the calculated value depends …
Electron Capture Detectors - Chromatography Online
Jul 1, 2019 · The invention of the electron capture detector (ECD) is attributed to Lovelock in 1957 (1). The detector measures the electrical conductivity of an effluent gas stream resulting from exposure to ionizing radiation from a radionuclide.

Feb 16, 2024 · Where V r and t r are the conventional retention volume and time, respectively. In SEC–formally–V r and t r can be substituted by V e and t e.The value of the retention factor is -1 < k ≤ 0. Please note that the official symbols of a column’s hold-up time and volume are t M and V M, but in many research papers and handbooks, the hold-up time and volume are denoted as t …
From Detector to Decision, Part III ... - Chromatography Online
Jan 1, 2024 · Gas chromatography is a premier technique for quantitative analysis. As gas chromatographs have become simpler to use and data systems more powerful, much of the data processing involved in delivering quantitative results now happens in the background and is seemingly invisible to the user. In this installment, we will review the calibration techniques used with gas chromatography.

Nov 1, 2018 · where p and q are the respective solute fractions in the two immiscible phases at equilibrium. (By convention, p is the solute fraction in the upper compartment or mobile phase and q is the solute fraction in the lower compartment or stationary phase). We can now see that the chromatographic theory, including peak broadening, is beginning to take shape.
