collection of trace and ultra-trace contaminants in water usually
employs an initial step of "pre-concentration". This pre-concentration
process increases the concentration of the contaminants, above the
detection limit of the chosen detector.
contaminants are present in very low concentrations (ultra-trace),
standard technologies become increasingly inefficient. The two standard
pre-concentration technologies are:
1) Filtration, based on physical trapping of particulate analytes
in inert porous barriers
2) Adsorption, based on surface adhesion of analytes onto chemically
activated "stationary phases".
trapping technology replaces both of these pre-concentration methods
with an exceptionally efficient "chemical trapping" medium
which chemically bonds and traps the small particles that stay suspended.
In some instances this can be as much as 1000 times more efficient.
EcoVu successfully captures and concentrates the ultra trace-level
contaminants where the current state of the art fails.
is also unique in that its novel chemical trapping process can be
used for both purification and analysis.
