This paper describes an instrumentation system for positron
emission tomography (PET). A variety of [1-11C]labelled
aldoses, such as [1-11C]-D-glucose, and galactose by a modification
of the Kiliani-Fischer method have been produced. The instrumentation
The detector, a multi-channel photometric detector, described in this
paper was developed using multi-wavelength LEDs (light emitting
diode) and phototransistors for absorbance measurement controlled
by an Intel 8031 8-bit single chip microcomputer. Up to four flow
cells can be attached to...
This paper describes the design and operation of a laboratory plant
with a fixed-bed continuous-flow reactor, fully automated and
controlled from a personal computer. The automated variables
include two gas flows, one liquid flow, six temperatures, two
pressures, one circulation of a cooling...
Bioanalysis is determining the concentration of drugs and
metabolites in biological fluids (i.e. plasma and urine). During
the past 15 years tremendous advances in bioanalysis, for example
HPLC, auto injectors, data collection systems and robotics has
enabled the productivity of the...
ELISAs for pesticides and herbicides in environmental and
agricultural samples are becoming very important in screening
applications [1-3]. Traditional chromatographic methods are
expensive and results need long turnaround times, making them
incompatible with rapid on-site decision making....
An automated method, based on the Hewlett-Packard ORCA
(Optimized Robot for Chemical Analysis) system, for sample
preparation and analysis of petroleum samples by simulated
distillation (SIMDIS) is described. Results obtained for the
robotically prepared samples show excellent agreement with...
