Plasma optical emissions
spectrometry analyzer
SPECTRO Analytical Instruments
has introduced the newest version of its
SPECTROGREEN inductively coupled
plasma optical emissions spectrometry
(ICP-OES) analyzer: the SPECTROGREEN TI, featuring SPECTRO's proven twin interface (TI).
SPECTRO's twin interface automatically combines both axial and radial plasma views-looking both across the plasma and from end-to-end-optimizing
sensitivity, linearity and dynamic range
while avoiding matrix effects like EIE.
According to the company, SPECTROGREEN TI (FIG. 1) offers the highest sensitivity for trace elements, freedom from
matrix interferences and good accuracy
for challenging environmental matrices.
The SPECTROGREEN TI is the
third and newest version of the SPECTROGREEN compact midrange ICPOES analyzer. It delivers numerous
advantages for a wide array of routine
laboratory analyses: innovation and versatility; top-flight functionality; solid
simplicity and ease of use; ensured durability and reliability; fast analysis for high
productivity; and affordability.
Other models include the SPECTROGREEN DSOI and the SPECTROGREEN SOP.
SPECTROGREEN is ideal for routine
elemental analyses in chemical/petrochemical, environmental and agronomy,
consumer product safety, pharmaceutical
and food applications.
SPECTROGREEN offers a competitive price/performance ratio and all models save on consumables with innovative
no-purge UV-PLUS and require no added
cooling, eliminating the need for expensive, breakdown-prone external chillers.
Additional features include SPECTRO's ORCA optical technology that
maximizes light throughput, stability and
sensitivity. SPECTROGREEN's transparency and light throughput provide high
performance for UV elements, and a DSOI

model, delivering twice the sensitivity of a
conventional radial view across the whole
spectral range. With access to the entire
wavelength range via a single analysis,
there is no need to choose a viewing mode
or make multiple analyses-a critical advantage for high-productivity laboratories.
The analyzer's GigE readout system
significantly boosts spectra processing
and transport speeds for faster analysis,
shorter sample-to-sample times and more
samples per hour. The thermal stabilization of the optical system is achieved
without sub-zero cooling. The analyzer's
optimized spectral range CMOS line array technology avoids blooming while
providing a fast readout and a wide dynamic range. The latest LDMOS 1,700W generator helps analyze difficult sample matrices in lower dilutions to lower
limits of detection while staying cool and
trouble-free, ultimately delivering a fast
warmup for higher productivity.
All sample introduction components
are readily visible and accessible with its
clean, compact design. Its new SPECTRO ICP Analyzer Pro operating software streamlines workflows. A modular
plug-in architecture allows for individual
customization. Processing speeds are ultrafast, even with large amounts of data.
The analysis process is fully transparent and traceable with version and user
management, plus excellent audit trail
functionalities.

Range of ball valves
increased
GEA has launched an addition to its
range of ball valves by adding the KVplus and KVplus cryo series of top-entry
ball valves designed specifically to operate with pressures of up to 100 bar. The
KVplus series is capable over the full temperature range from -50°C-200°C; and
the KVplus cryo series is capable over the
temperature range from -196°C-100°C.
This makes the KVplus and KVplus cryo
series suitable for use with natural refrigerants (NH3 , CO2 ), cooling brines, and

non-corrosive gases and liquids, according to EN 378-1.
The new valve series completes the
range-with its engineering being in high
demand for many marine applications-
for use in chemical factories and as a key
component in heat pump technology.
They are equipped with an anti-blowout
stem, are fire safe tested according to ISO
10497 and API 607, and the stem-sealing
system is compliant with ISO 15848 as
" technically emissions free. "
The design allows maintenance and
inspection work to be completed without
having to disconnect the valve from the
line. The bi-directional seal/seat system
operates irrespective of the direction of
flow. When in the " closed " position, the
pressure is automatically relieved via the
seat system of the valve.
Operation is by manual hand lever or
can be used with electric or pneumatic
actuators, if required. The KVplus series
valves are built within a one-piece, bolted
stainless-steel housing. This provides the
necessary strength to handle the most demanding applications.

Cooling and lubricating
the shaft seal on
centrifugal pumps
Centrifugal pumps depend on cooling and lubrication to operate efficiently,
reliably and with a long service life. The
solutions commonly used for this purpose in industry are mainly constructions
