The advantages of such a well-known technique as atomic absorption (AA) spectrometry are implemented to the full extent and the technique itself is brought to perfection in the MGA-915 Atomic Absorption Spectrometer and RA-915+ Mercury Analyzer. They are made to be state-of-the art, convenient, accurate and extremely sensitive instruments due to the use of the Zeeman atomic absorption spectrometry with high frequency modulation of light polarization (ZAAS - HFM).

The high sensitivity and selectivity of the instruments make the requirements for the sample preparation and weight much less stringent. The polarization modulation device embodies novel design features and components.

Capillary electrophoresis (CE, or, originally, high performance capillary electrophoresis) is a relatively new technique which relies on a separation and subsequent quantification of the components of the complex mixtures. The separation is based on the differential migration of the components inside the quartz capillary under the influence of the applied electric field. Lumex has designed and put on the market Capel CE series of instruments which feature all advantages typical for capillary electrophoresis:

• Since migration of the analytes occurs due to electrically-driven forces, no high pressure precision pumps are needed

• Very low reagents and samples consumption

• Very low analysis cost

• Very fast analysis time

• The absence of any solid material in the capillary excludes the problems of its aging, chemical or physical destruction or unspecific binding with sample constituents

• Separation efficiency can be extremely high, up to 1.000.000 theoretical plates

Scope of application: Since CE ensures very high separation efficiency, it can be used for the separation of numerous compounds with very similar structure. It is widely used in pharmacology and pharmacokinetics for the analysis of drugs (including drugs of abuse) in raw materials and in biological fluids, in environmental studies for the analysis of pollutants, inorganic cations and anions, in chemical and food industry for technological and quality control and in various fields of scientific research (analysis of proteins, peptides, oligonucleotides, viruses, etc.).

For many years the photometric analysis techniques were dominating in most of ecological, sanitary, technological, and biochemical laboratories. However, as the requirements for the ultimate tolerable concentrations (UTC) have become more stringent, the luminescence techniques are being widely used for assaying many of the substances, especially for low detection concentration, and are preferable to the absorption photometric techniques due to the following advantages: 

• the high selectivity of the luminescence technique allows the number of the sample preparation stages to be reduced and the reliability of the assay to be enhanced (Zn, Cu, Al); 

• the high sensitivity of the technique allows operation with small-volume samples, thereby speeding up sample processing during each stage of the sample preparation, and reducing the consumption of reagents (surfactants, formaldehyde, Cd, Sn, Cr, Al, Cu); 

• it is possible to detect the components which are undetectable by the photometric technique because of their low UTC (phenols, As, B, Be, Se, U, B-vitamins) or need the use of a special-purpose IR-absorption photometer (petroleum hydrocarbons).

In modern spectroscopic instruments the IR absorption, transmission, or scattering spectra are detected by scanning the phase shift between two split parts of a light beam, which is the essence of the Fourier-transform spectrometry.
This technique provides a significant gain in photometric accuracy and frequency precision. The InfraLUM^® FT-02 mid-IR FT and InfraLUM^® FT-10 near-IR FT spectrometers, featuring a state-of-the-art robust vibration- and misalignment-proof design, allow a user to conveniently perform a variety of analytical functions.

Mid IR spectrometry is used for identification of an unknown substance, qualitative and quantitative analysis of solutions, mixed substances or complex natural objects, detection of impurities in atmospheric air and gases and a functional structural analysis.

To facilitate performing the analyses, the instruments are furnished with a variety of accessories, dedicated SpectraLUM control, data acquisition and processing software package, and calibration and reference databases.

Using a correlation analysis from the near IR spectrum of a sample an analyst can also determine its physical and chemical properties or biological characteristics, such as sprouting ability of seeds, caloric content of food products, grain size, density, etc.
