LEA - S500 - the modern powerful nuclear and issue spectral device with multichannel registration of a range uniting innovative technologies in the field of laser, spectral, measuring, digital equipment and the software, allowing to define element (chemical) structure of test in only a few minutes.
The defined elements from H to U, measurement range from 1 rrm to 100% . The mass of substance necessary for the analysis - from 50 nanograms. Time of implementation of the multielement analysis taking into account time of sample preparation of 1 - 15 minutes. Time of implementation of 400 analyses by determination of uniformity of material about 7 minutes.
Intuitively clear software of LEA - S500 guarantees full use of the device from the first day of operation.
Development of basic functions requires several hours and a minimum of special knowledge.
The Dvukhimulsny nanosecond laser source of excitement of ranges, thanks to high power, spatial and temporary stability, provides the maximum reproducibility of results of the analysis and low limits of detection of chemical elements and connections. Simultaneous realization of the arc and spark mode of excitement of ranges is provided.
High - quality high - aperture bezabberatsionny spectrograph
with high spectral resolution guarantees exact and reliable measurements
The unique system of registration of short - term pulse light signals allows to reach record - breaking low limits of detection of elements and linearity of concentration dependences in the wide range.
Advantages
- Measurement of a mass fraction (concentration) of chemical elements or their connections (oxides) in the analyzed test with the minimum sample preparation
- Express multielement analysis
- The full analysis of a chemical composition for one measurement
- High sensitivity and pretsizionnost of measurements in the wide range of concentration
- Change of an aggregate state of tests is not required
- The analysis of tests in the set points (areas) of a surface by means of systems of positioning and video surveillance
- Layer - by - layer analysis of coverings, films, raids, korroziya
- Analysis of inclusions, defects, defects
- The analysis of distribution of elements in test with a step from 30 microns. Creation of cards of distribution of elements on a surface and depth
- Especially pure reactants for sample preparation are not required
- Expensive expendables are not required
- Inert gas for the solution of the majority of tasks is not required
- Cleaning of the polluted surfaces of tests with preliminary impulses of the laser is carried out
- Universality: the device does not demand readjustment or modernization for the solution of all listed tasks
- Analysis of conducting, not conducting materials
- The analysis of a wire of any diameter, balls, cylindrical details without additional processing by means of adapters (are included in a package)
- Uncompromising safety of work, full protection of personnel against influence of harmful factors
Analytical opportunities
The full (multielement) quantitative analysis of test taking into account sample preparation - from 1 to 15 minutes.
Analysis of any solid and powdery materials:- ceramics, glass, cement
- metals and alloys
- slags
- rubbers, rubbers, plastic
- impurity and minerals in pure materials
- chemical reactants
- ores, minerals and monomineral inclusions
- natural materials (clays, sand, dolomite, soda, salt, etc. )
- ashes of a vegetable and animal origin
- materials from wood
- dry rest of liquids
- the frozen liquids
- soils
- dry plant materials
and other materials.
The qualitative analysis - 50 elements within 5 minutes.
The analyzer of element structure LEA - S500 allows to carry out definition of a chemical composition of any firm tests without change - over of the equipment. Transition time from the analysis of one type of tests to the analysis of other type of tests makes several seconds.
