Dear Sir/Madam,
Our partner the Lumex Ltd. invites you to visit its stand
F20, hall 003 at the
Biotechnica - 2003
This exhibition will be held in October 7 through 9, 2003,
in Hannover, Germany. During the exhibition the company will
display the following instruments:
Flourat-02-3M
Analyzers
CAPEL-105
Capillary Electrophoresis Systems
RA-915+
Mercury Analyzer
LaSca
Laser Particle Analyzer
During the exhibition the Lumex Ltd will offer two presentations
concerning its Capillary Electrophoresis Systems and Laser
Particle Analyzer.
Below you will find the theses of both presentations.
Capillary electrophoresis for the analysis of substances
of biological importance
Vadim M. Okun, Lumex Ltd., St. Petersburg, Russia
"In the last 2 decades capillary electrophoresis (CE) has
emerged as a powerful tool for the analysis of different substances
in various fields of fundamental and industrial sciences.
The absence of solid support in a capillary where a separation
takes place makes this especially favourable for bioanalytical
studies, since it offers to a considerable extent the in-vivo
situation where the molecules are free in solutions.
There are kinds of molecules such as proteins, nucleic acids,
and even viruses that can be analysed by CE. Important parameters
underlying the affinity properties can be also determined.
We present here a full automated CE system Capel-105, which
is a most upgraded version of well-known instruments from
Capel series. Highly effective cooling of a capillary enables
operation at a high voltage and short capillaries thus improving
the efficiency of separation. Integrated microprocessor helps
create a very flexible program of analysis with variable time
and parameters events. Different models of CE, including capillary
isoelectric and affinity CE, can be realised on the system.
The examples of most successful separations of biomolecules
achieved with Capel CE system are given."
LaSca.
Light scattering in biotechnological and other applications.
Igor E. Jahatspanian, Igor V. Mindukshev, Lumex Ltd., St.
Petersburg, Russia
"For several years Lumex Ltd.
has been developing a new series of particle analyzers LaSca
based on laser light scattering. The measurement of particle
characteristics in the 0.5-100 μm range is ideally suited
to meet the needs of scientific research and various applications
in geology, mineralogy, metallurgy, life sciences (haematology,
cytology, serology), pharmacology, and biotechnology. The
developed technique employs a new mathematical approach to
the determination of particle size distributions and kinetics
of heterophase processes.
In biotechnology, the cell concentration (biomass level) and
specific growth rate (μ) are the most important parameters
for fermentation control. Therefore, on-line measuring of
biomass and μ is necessary for control and automation of
the cell cultivation processes. The laser scattering technique
can be used in a number of biotechnological applications,
such as
- On-line monitoring of cell concentration in terms of g/L
throughout a biotechnological process;
- Continuous calculation of μ
- Measuring the cell size distribution and evaluating the
population index.
This technique can be used for the bacterial and yeast cells
cultivation control.
We present here an automated particle size analyzer LaSca-biotech,
which is a dedicated version the LaSca series instruments
specially adapted for biotechnological applications. The principle
of the analyzer operation is based on measuring the scattering
angle diagram of a laser beam passing through a measuring
cell with a sample. Cell suspension from a fermenter is continuously
pumped through the measuring cell of the device and then is
returned to the fermenter. All liquid ducts and the flow cell
can be readily removed from the device and sterilized by stream
or chemicals. The analyzer is equipped with a bubble separation
system."

We
present RA-82 mercury analyzer |
|
We present RA-82 mercury
analyzer, which is specially designed for field ecological
and geochemical surveys:
- measuring weight concentration of mercury vapor
in ambient air and soil gas, as well as in the indoor air
in residential and production areas.
- detection and localization of indoor and outdoor mercury
pollution.
- monitoring the demercurization process.
- ore deposits survey using mercury haloes in soil gas.
Atomic absorption spectroscopy is employed for measuring
weight concentration of mercury, which is implemented using
a double-beam optical scheme with analytical and reference
cells. To minimize the detection limit, mercury preconcentration
on a gold trap is used.
The instrument operates in two main modes, DISCRETE
and CONTINUOUS. The DISCRETE mode is used for quantitative
measuring the mercury concentration from 50 to 99999 ng/m3.
The CONTINUOS measurement mode is indicative and is used
for rapid detection and localization of mercury contamination
sources, mercury concentrations being 500 to 1x106 ng/m3.
