designs of mass spectrometers based on time-of-flight reflectron systems coupled with laser desorption/ionization sources
have been developed (Managadze TOF-R). The instruments were used in several space programs both in Russia and USA. Continuous
developments result in a new class of miniature high sensitivity instruments that can be used both in space and in land applications.
Analysis of microbial life on planets (such as Mars) as well as identification and monitoring of living and fossilized microbes
is possible with high precision.
Fenixtec is now capable
of delivering components and complete mass spectrometry systems of special design needed by research and industry. Among systems
LARMOR - for chemical analysis of organic
compounds in solids; the instrument design is based on completely axis symmetrical mass analyzer with pulsed laser ion source;
it can measure quantities of organic molecules with weight range between 1 and 10,000 Daltons.
LASMA - Mass reflector with a laser ion source. Main applications
are in determining elemental and isotopic compositions in solids such as multi-component alloys, ceramics, soils and powders
without sample preparation. The instrument can also be used for analysis of liquids with high vapor density, e.g. technical,
residual and raw oils. LASMA has a unique combination of analytical, maintenance and weight-size characteristics. The ability
of simultaneous detection of all periodical system elements and their equiprobable yields registering each spectrum in less
than 0.1 msec. Mass range - 1 to 250 amu, Mass Resolution - up to 600,
Sensitivity - in femtogram range
MALDI-TOFR - On-Board Instrument for Space Missions
This is a proposed innovative concept to detect and identify microbial forms on Mars and other
planets by developing a simplified sample preparation method and a compact time-of-flight (TOF) mass-reflectron for registration
of organics in the solid phase. A lipid biomarker methodology will be used to identify potential microorganisms. The determination
of the presence or absence of microbial life can be supported with Matrix Assisted Laser Desorption/Ionization ( MALDI)-TOF
mass-spectrometry of lipids and saccharides extracted from Martian samples that could host microorganisms. Microorganisms
can be in viable vegetative or dormant form, as well as non-viable (fossilized). Samples of Martian soil will be collected
from the depth of at least one centimeter utilizing a low revolution bore. Finely ground samples will be used as the matrix
for MALDI-TOF sample preparation. The main deliverables will be the design of a compact fully axially symmetrical reflectron
operating as a MALDI-TOF-MS, the development of a simplified sample preparation methodology, and concepts for designing a
sample transfer unit for delivery into the instrument. As a follow-up an onboard system prototype will be designed and constructed
with corresponding software, and the commercialization path will be identified (potential applications for detection of minute
traces of microorganisms in various environmental samples; the instrument can potentially be used as part of robots to detect
traces of biological or chemical weapons).
