The infrared absorption spectra in the out-of-plane
bending (v₂) region of potassium nitrate were studied for
three phases. Several types of sampled were used: nujol
mulls, fused samples, and N¹⁴-N¹⁵ isotopic mixtures. The
existence of three of the reported polymorphic phases was
confirmed by the spectra. The transitions between phase...
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
designed and...
