The samples, rinsing and buffer solutions are injected automatically by pressure or electrokinetically according to a preset program. All the instruments are equipped with capillary cassettes, containing air (103)- or liquid-cooled capillaries of 30-100-cm in length and 25-100 ³m i.d., reversible polarity 25 kV voltage supply units, and with customized report outputs (hard copy and file). The dedicated software package supports data acquisition and processing, data exchanges with worksheets, databases and word processors. The software package utilizes a standard PC and powerful Chrom&Spec software package. The Capel-105M version is fully computer-operated, using dedicated Elforun software

FLUORAT^®-02-Panorama Spectrofluorometer incorporates two monochromators in the luminescence excitation and detection paths, which are arranged in a compact two-storied configuration, a xenon flashlamp as a light source, and a PMT as a detector of luminescence signals. The monochromators employ 900-l/mm concave diffraction gratings with a 100-mm radius of curvature, covering the 210-730 nm (up to 840 nm opt.) spectral range. The wavelengths are set either from a built-in keypad or using a computer control program. The instrument is intended for analysis of liquid and solid samples by luminescence spectra, chromatographic analysis of several components during a single eluation, and synchronous or two-dimensional spectra scanning in both excitation and luminescence detection paths.

FLUORAT^®-02-series Analyzers embody the modular principle to diversify the highly sensitive and selective luminescent analysis technique employed. The base unit, FLUORAT^®-02, is a filter fluorometer, photometer, and chemoluminometer, all implemented in the same optoelectronic scheme, whereas the FLUORAT^®-02-2M version is, in addition, a time-resolving fluorometer, which can be used as a fluorometric detector in any HPLC system. The analyzers are equipped with high-pressure xenon arc lamps, which emit high-intensity light in the 200-650-nm spectral range, and are furnished with appropriate sets of light filters and measuring cells. FLUORAT^®-02-02/3M analyzers operate in a user-friendly custom menu mode to analyze standard-list contaminants, such as petroleum hydrocarbons, phenols, surfactants, formaldehyde, nitrites, nitrates, sulfides, fluorodes, and a number of elements, save calibration tables and background value for 16 different components in the built-in memory, and can print out analysis results. These analyzers can also operate with a fiber optic light guide to measure luminescence or reflected light from the surface of an outside sample, such as paper, cathodoluminophors, etc. The small (300x300x90 mm) and light-weight (8 kg) analyzers are energized from an ac mains or from a 12-V battery, which allows their use in mobile laboratories.

CRYO-1 and -2 Cryogenic Systems are, respectively, intended for cryospectroluminescent analyses of benz(a)pyrene in various objects and of lead in samples of potable, natural and waste water, and in food products (in addition, Bi, Te, and Se can also be detected). The systems comprise a FLUORAT^®-02-2M analyzer and a cryogenic unit (plus an LM-3 monochromator in Cryo-1), which are connected with one another via fiber optic bundles. The cryogenic unit, where a substance under study is cooled to 77K, using liquid nitrogen consists of a rack, Dewar vessel, and a device for the uniform feed of samples being measured.

HPLC system is made up of a FLUORAT^®-02-2M analyzer, used as a detector, and a Python pump. The FLUORAT^®-02-2M analyzer enables the detection of mycotoxins, hormones, nitroso amines, histamine and other biogenic amines, benz(a)pyrene, vitamins, etc. To record chromatograms, the analyzer is equipped with an RS-232 interface. A built-in microprocessor provides signal processing, acustomized report, and makes the output signals compatible with the dedicated chromatographic data processing PC Multichrome software. The Python syringe-type pump provides a precise and predictable pulsation-free eluent flow and pressure. It is specifically designed to handle aqueous, organic, corrosive, and viscous liquids. The pump has a multifunctional control unit with a built-in keypad, which simplifies routine operations. Two pumps operating together can build up an eluent gradient.

To carry out very complicated analyses, for example, to analyze polyaromatic hydrocarbons, it is convenient to use a spectrofruorimetric FLUORAT^®-02-PANORAMA analyzer. This instrument enables program-controlled adjustment of both monochromators as a function of the eluation time. In this configuration, several compounds, for example, 15 specified polyaromatic hydrocarbons, can be detected with the highest sensitivity.

AKMC-1 Water Hardness Monitor is designed for stand-alone unattended continuous monitoring. The principle of operation is based on potentiometric determination of the high or low range (0.1 to 250 ppm) content of calcium and magnesium ions in any natural or industrial water samples. The device may be used for monitoring at water preparation facilities and for quality control of feed water in power plants and in artesian-well water softening. The design of the instrument provides uninterrupted measurements of ion concentrations in real time with automatic correction for variations of temperature in the water flow. It is equipped with RS-485 and RS-232 computer interfaces for customized report output and remote computer-aided control. Concentration measurement results, up to 1000, are stored in a built-in memory and are displayed on a built-in LCD or can be printed out.

CKAT-1 on-line Turbidimeter Monitor is intended for stand-alone unattended continuous monitoring in ecological, technological and sanitary purposes. Principle of operation of this device is based on the effect of light scattering by suspended particles and emulsions. The instruments comprise a light source, a water flow-cell and a matrix of photodetectors and allow to detect a turbidity in any natural and industrial water flows. The instruments are equipped with RS-485 computer interfaces for customized report output and remote computer-aided control. Concentration measurement results, up to 1000, are stored in a built-in memory and are displayed on a built-in LCD or printed out. If the analysis result exceeds a permissible level, the alarm mode is activated, and a final-control mechanism can be automatically switched off by a command from the flow analyzer.

RA-915+ Mercury Analyzer is a portable multifunctional atomic absorption spectrometer with Zeeman background correction, which eliminates the effect of interfering impurities. It is the only high sensitivity and selectivity instrument that does not require gold amalgam pre-concentration and subsequent regeneration steps. This enables the user to conduct real time monitoring. Being combined with an RP-91 Cold Vapor accessory for water and RP-91C pyrolysis attachment for solid sample testing, the instrument is designed to determine mercury content in ambient air, water, soil, natural and stack gases, dental and medical testing and diagnostics, analysis of food and marine life, etc., the detection limits being as low as 2 ng/m3 in air and 0.5 ng/l in water.

MGA-915 Atomic Absorption Spectrophotometer with electrothermal sample atomization and enhanced Zeeman background correction features a compact benchtop design, incorporating a fast 62.5-mm focal length monochromator with a 1200-l/mm grating covering the 195-600 nm spectral range, automatically controlled Massman graphite furnace, and automatically interchangeable 6 hollow-cathode lamps or EDLs on a rotated turret. It enables an analysis of more than 60 elements, primarily heavy and toxic metals, to be carried out with very low detection limits in such complex organic samples as milk, juices, wines, or blood without preliminary sample digestion in a totally automated computer-aided operation mode, including automated adjustment for the given element. The spectrophotometer is equipped with a 100-position autosampler.
