Measure every liquids'
'fingerprint' in real time
This company has developed a new
radio-wave-based analysis technology
that enables continuous monitoring
of the state of any liquid, including
thick slurries, resins, adhesives,
coatings, emulsions, beer, water and
more. The Collo Analyzer (photo) has
an electromagnetic resonator that
emits a continuous radio-frequency
field into the liquid. The signal reacts
to interferences caused by different
components, chemicals and phases
in the liquid. The analyzer immediately
warns if the process is disturbed
in any way so that the process can
be adjusted according to the online
data. The sensors can be placed
anywhere in the process to optimize,
for instance, the use of raw materials
and chemicals in critical process
steps. In brewing, for example, the
Collo Analyzer simultaneously measures
eight proprietary parameters
from a liquid, which together form the
liquid's fingerprint. If these characteristics
are changed during processing,
the analyzer shows the changes
so that corrective measures can be
taken immediately. - ColloidTek Oy,

Color measurement moves
from the lab to the process
Color measurements are employed
for
quality
control and safety
the device to determine colors, color
variations or the accuracy of the expected
colors. The mathematical
analysis models required to analyze
the spectroscopic results are stored
in the instrument. The CKI50 uses
the Memosens protocol to connect
to the Liquiline transmitter, which forwards
the data to the process control
system. - Endress+Hauser AG,

many sectors of the chemical process
industries (CPI), including life
sciences, food, chemicals and petrochemicals.
In many cases, the
samples are taken from production
and brought to the laboratory where
they are analyzed, after which the
batch is released. Shifting this step
directly to the process enables realtime
monitoring and control, particularly
across the entire production
process. The Memosens Wave
CKI50 process spectrometer (photo)
enables robust inline quality control.
Using visible (VIS) absorption
spectroscopy, the CKI50 scans the
380-830-nm wavelength range of
the electromagnetic spectrum and
outputs the color in the form of a 3-D
color-space model, which enables
This TDLS ammonia analyzer
operates with a tablet
This company was asked to develop
an ammonia analyzer that
could be used in the research and
development of ammonia-powered
engines. The requirements for this
application included features such
as high selectivity for ammonia, fast
response time, low maintenance/
calibration requirements, long-term
reliability and the ability to measure
a hot/wet gas continuously. Tunable
diode laser spectroscopy (TDLS)
meets all of these requirements, so
the company built the analyzer into
its Series 4 range to make the S4
Nebula (photo). The analyzer features
a detachable tablet, which enables
users to operate the analyzer
wirelessly from a convenient location
nearby, using the instrument's
built-in Wi-Fi. - Signal Group Ltd.,

Multifunction analyzer for
boiler-water treatment
The CE800 Series (photo) is a family
of online cation conductivity analyzers
that detect a wide range of
contaminants, which contribute
to
the buildup of corrosion and scale
in boilers, turbines, piping and other
expensive equipment that requires
maintenance and shortens life. Cation
conductivity is the measure of electrolytic
conductivity of a liquid sample
after that liquid sample has passed
through an ion-exchange resin column.
The conductivity of makeup
water, feed water and condensate,
after passing through this column
of strongly acidic cation exchanger
resin, is an important chemical meaCHEMICAL
