Jn. Vandermoolen et al., CORRELATION CAPILLARY ZONE ELECTROPHORESIS, A NOVEL TECHNIQUE TO DECREASE DETECTION LIMITS, Chromatographia, 40(7-8), 1995, pp. 368-374
The application of multiple injections and correlation techniques in c
apillary zone electrophoresis, a method known for its high detection l
imits, is described. An experimental electrokinetic injection device,
particulary suited for fast and reproducible multiple injections is us
ed in combination with a conventional CZE system. The results show a c
onsiderable reduction of the detection limit, in agreement with the ex
perience in the already fully developed correlation chromatographic me
thods, and in agreement with the theoretical predicted values.
