Mass spectrometer MAT 250
It is a mass spectrometer special for isotope analysis of deuterium, oxygen-18 and carbon-13, in natural range, which has in subsidy ions sources with electronic
bombardment, magnetic analyser with deflexion at 90º and two systems of ions receiver assays for small masses (2 and 3 u.a.m.) and for high masses (28 ÷ 64 u.a.m.).
In subsidy of Mat 250 spectrometer is a system for liquid assays conversion into gas for D/H analysis with a CO2 isotopic equilibration system with water
assays for O18/16O.
Cycling system has a turbo molecular pump which vacuum analyser system (10-8 torr), ionic pump and preliminary vacuum pumps.
Introduction system is symmetrical dual for simultaneous introduction of assays and reference standard fit to gas.
Mass spectrometer GD 150
It is a mass spectrometer special for isotope analysis of deuterium 50-5000 ppm.
Ions source has electronic bombardment, isotope separation is realized using magnetic deflexion at 180º ions double collector for concurrent collecting of ions whith 2 and 3 mass.
Introduction system is special for hydrogen and it has a warming uranium furnace to 650ºC, for reduction of water to hydrogen. This reduction must be done entirely to
maintain the initial isotopic content of assay.
The acquired ions source are focalized into a system of electrostatics lenses and get into a magnetic field who is perpendicular on ions trace, cover a semicircular traictory
which has radius dependent on mass ratio (q/m).
Gaz-chromatograph Varian 3800
Is provided with:
- dual system of detection: detector - TCD si FID;
- dual system of measure and referent;
- temperature range at furnace is between: -99ºC ÷ + 450ºC;
- operating system of temperature at columns with 6-8 stages;
- system provided with dual holder of injection for manual and automatic measuring of samples with 1 µl to 1 ml gas;
- Types of columns with various filler dependency by type of detector (for FID detector - capillary columns of various size
and with adequate fillers for qualitative and quantitative analysis of samples).
Gas chromatographic analysis are applied in following areas:
- the control of technological processes - separation and purification of gas;
- analysis for environment monitoring;
- food industry - control atmospheres for food conservation, juices and alcohol beverages;
- mixture of gas and various standard production.
Spectrophotometer for atomic absorption NOVAA 300 - Analytik Jena
Is provided with:
- pulverizing system - burner that monitoring the burning gas pressure and oxidant pressure, the level from siphon and flame;
- Czerny-Turner single chromator optimized, with automatic selection of wave length (work range 190-870 nm);
- hardware system for correlation of system running based on input data and on output data;
- software that estimate and control analysis data, with intern floppy-disk and connection for printer, screen with screen tuch.
The program is the same with that used to PC systems; it control, monitoring and verify all spectrometer of atomic absorption parameters and functions.
Analysis method that use spectrophotometry of atomic absorption is sensitive one, with a wide practicability, because engage volatilized atoms in flame.
There is analyzed metallic ions 0.01 to 10 mg/liter.
Practicability range: metallurgy, chemical industry, alimentary industry, control of aerial water, residual water, potable water and soil.
Spectrometer with low level liquid scintillation, Quantulus 1220
It is a spectrometer with low level liquid scintillation which allow environment assayes
measurement without use of enrichment techniques, which are used in tritium case, so it is obtained a low cost of
analysis and a low time consumtion.
