Method allowing control of an evaporative light scattering detector which
is coupled to a liquid chromatography column, substantially independently
of the elution conditions for the chromatographic separation.
A given adjustable constant calibrated volume of the flow which originates
from the chromatography column is removed at a given adjustable
frequency, this flow being constituted by an eluent which contains
compounds to be analysed which have been dissolved therein, and the
volume removed in this manner is transferred to a secondary circuit, to
which the evaporative light scattering detector is connected, by being
conveyed by means of an auxiliary pump with a specific carrier fluid
which is independent of the eluent having a predetermined flow, and the
successive fractions of the flow which originates from the chromatography
column are mixed with the carrier fluid which conveys these fractions
upstream of the evaporative light scattering detector.
