Analysis of kinetics and concentration dependence of electron-capture detector

Effect of positive ion/molecule reactions on the response of the electron capture detector to anthracene

“…Additional Detail for Models of the ECD. The results described above provide additional detail to recent models (11,19,20) of the chemical dynamics operative within the pulsed ECD. In particular this new information should affect our view of the generalized reactions shown below.…”

Experimental parameters affecting hypercoulometric response in gas-phase coulometry

“…Collection of Positive Ions. Wentworth and Chen (9) have suggested that nonlinear response can be associated with nonconstancy of the electron-capture coefficient, K,…”

“…response (8,9). These observations may be due to (i) formation of "second-generation" electron-absorbing products (reactions 3 and 4, see ref 3), (ii) regeneration of electron-X--Y-+ Z…”

“…(5) charged particles within the detector (9,(11)(12)(13), (iv) uncompensated losses of the reagent (the electron in reaction 2) in the presence of strong electrophores (14), or (v) contamination of the reaction vessel. Given these complications, some further investigation of the practical aspects of gas-phase coulometry seemed advisable before proceeding with a series of halocarbon analyses based on an assumption of coulometric behavior.…”
