Detection
from Evaporative Light Scattering is based on the universal ability of
particles to cause photon scattering when they traverse the path of a
polychromatic beam of light. The liquid effluent from an HPLC is first
nebulized and the resultant aerosol mist, containing the analyte particles,
is directed through a light beam. A signal is generated that is proportional
to the mass present, and independent of the presence or absence of chromophores,
fluorophores or electroactive groups. Since essentially every compound
can be separated by HPLC or micro-HPLC and detected by ELS, the ESA ChromaChem
is the detector every chromatography laboratory should have.
The
Chromachem Evaporative Light Scattering detector is a mass sensitive device,
which provides a response directly proportional to an analyte¡¦s mass in
the sample. The presence of functional groups or chromophores are not
necessary for detection. Relative amounts of compounds can be easily assessed
by evaporative light scattering technology. Any non-volatile analyte can
be detected and gradient elution can be employed to optimize the separation,
aqueous as well as solvent based mobile phases can be used to detect compounds
that are not generally "seen" by other detection techniques.
This detector can be used in conjunction with mass spectrometers to provide
a complete analysis of the sample.
The
Chromachem's unique nebulization system and temperature controlled drift
tube provides sensitivity, reliable and reproducible analysis. The unit's
small footprint requires a minimum of bench space, allowing use in space
limited conditions.
