For a regular chain R, we propose an algorithm which computes the
(non-trivial) limit points of the quasi-component of R, that is, the set
W(R)ΛββW(R). Our procedure relies on Puiseux series expansions
and does not require to compute a system of generators of the saturated ideal
of R. We focus on the case where this saturated ideal has dimension one and
we discuss extensions of this work in higher dimensions. We provide
experimental results illustrating the benefits of our algorithms
