Iskroline 300

Availability: in stock

ISKROLINE 300 atomic emission spectrometer is a laboratory grade analytical instrument for express analysis of metals and alloys with any bases. It was designed for solving the tasks when the user cannot afford compromising performance in favor of size, and the following spectrometer capabilities become top priority: measurement accuracy and repeatability, user friendliness and robustness.

Today ISKROLINE is the flagship of our spark spectrometers. It is an ultimate approach to product quality and functionality. Precision mechanical components and optical settings and repeated stress testing of all electronic components guarantee exceptional build quality of the product.

What is the purpose of this instrument? Primarily, it can perform the same functions as the less sophisticated ISKROLINE models. ISKROLINE 300 will quickly perform all these tasks. Yet, some other problems, that have a more complex nature, cannot be efficiently resolved with the aid of compact spectrometers (neither of the brands available in the market). Such problems include quantification of purity and super purity metals (copper, aluminum, lead, etc.) on the one hand, chemical analysis of complex and super complex alloys on the other hand.


The instrument detects spectral lines within 174-930 nm range, including the lines of P, S and C, gases (N2, H2, O2), alkaline (Li, Na, K, Rb) and alkaline earth (Be, Mg, Ca, Sr, Ba) elements.

The operating spectral range is quite extensive. At the same time, due to the unique spectrograph setup procedure, its resolution comes close to the theoretically possible limit (due to optical unit dimensions). The natural width of many analytical lines increases the resolution capabilities of the hardware, which allows assessing their actual spectral width. This and some other features of the instrument allow its lab application for R&D purposes.

ISKROLINE 300 is a best-in-class laboratory emission spectrometer in terms of price/analytical capability ratio enhanced by its quality and reliability. The instrument consists of a spectral excitation system based on a SPARKS LCR discharge generator, a 2S36501633 vacuum spectrograph, a 30 linear CCD detection unit, control, gas supply and vacuum systems, housing and operator chair.

Special features

  • High speed (below 30 s).
  • Low argon consumption due to the unique process of deoxygenation of the spectral unit.
  • High efficiency of LCR discharge generator (in ballast resistance off mode the discharge can be powered by as much as 80% of the main power).
  • Extended generator setup range (over 700 combinations).
  • All electrical parameters of the generator related to the metrological performance of the spectrometer are controlled.
  • A wide table allows processing large (over 10 cm) and irregularly shaped samples.
  • This model also features the most efficient solution for high transmission wide range spectrographs, i.e. a tandem spectrograph. Two Paschen-Runge spectrographs share the same optical based and are optically linked at the zero diffraction order of the first unit.
  • Exceptional thermal stability achieved without costly solutions without costly solutions.
  • The super high sensitivity of Iskroline 300 within the wavelength range below 185 nm, the airtight casing of spectrograph is vacuum pumped to a residual pressure below 0.1 mBar (10-4atm).
  • Such vacuum pumping is performed by oil-sealed rotary vane pumps at a minimum initial pumping rate of 5 m3/hour.
  • The pumps are equipped with cost effective heavy duty filters to prevent oil vapor release both into the vacuum chamber and into the environment.
  • The registration system digitizes the CCD analog signals in 16-bit format and saves the output in the internal memory (the memory capacity allows storing up to 500 frames). Digital signal pre-processing.
  • Iskroline 300 features a registration system supporting up to 30 CCD units.
  • Synchronized processing of all linear CCD signals allows subsequen correlation processing of data.
  • Frame accumulation time may vary within 0.004 — 60.0s range at a 0.004 s increment.
  • The design of the detection registration system circuit board is designed to resist harsh operating environments, i.e. vicinity to powerful EMI sources (spark, arc, HF and SHF discharge generators) or operation low pressure environment(up to 0.001 mBar) which causes reduced heat exchange.
  • Iskroline 300 is operated on the latest «PPM Pro» software version which is WindowsXP/7/10 compatible and controls the spectral excitation, registration, argon supply and vacuum systems.
  • This control software supports three user access levels for various operator skills, from routine measurements (beginner lab technician level) to creation of new and revision of the existing analytical programs (for highly skilled spectral analysts);
    • records and outputs in graphic format spectral data with easy navigation across the spectrum, spectral line identification, etc.;
    • includes a large database on spectral lines for their identification within the spectrum and qualitative evaluation;
    • allows personified adjustment for background amount and behavior on line by line basis for signal detection net of unwanted plasma emission, which is beneficial for sensitivity and accuracy;
    • allows using several analytical lines for each analyzed element, thus delivering by default hundred and thousand fold expansion of the dynamic range concentration wise, thus delivering virtually unlimited capabilities for analyzing the maximum concentrations of impurities;
    • allows enabling/disabling auto adjustment for inter-element additive and multiplication effect;
    • allows adjustment for base dilution;
    • allows single and double point recalibration;
    • includes a module for auto identification of alloy grades in accordance with Russian and international standards.

* - maximum concentration level of impurities detectable by Iskroline spectrometers is virtually unlimited due to synchronized elemental content quantification on several high and low intensity analytical lines of the related element (so-called “strong” and “weak” lines). It is the “weak” lines that help to increase the dynamic measuring range concentration-wise hundred- and thousand-fold.
