An on-line trace enrichment (TE) system, based on high pressure
liquid chromatogroaphy (HPLC) and flame atomic absorption (AA), has
been developed for trace metal analysis. The sample is pumped through
a column filled with a cation exchange resin which traps metal ions.
The ions are subsequently stripped from the column...
Studies of the use of NADH as the monitored fluorophore for enzymatic fluorescence kinetic methods are discussed. Interference studies
for the detection of NADH and the adaptation and optimization of fluorescence kinetic measurements to four serum assays are also described.
A microcomputer-controlled flow injection analysis (FIA) system was
A water-to-water heat pump was specifically designed and operated
to temper process water for cleansing and sanitizing milking parlor
equipment using recovered energy from the milk refrigeration system as
its heat source. Operation of the water-to-water heat pump in series
with the energy recovery system was found to be both...
