ICP-MS AGILENT 7900 ORS
ICP-MS is a powerful, fast multi-element analysis technique for determination of elements within low detection limits, even up to ng / L, with a ± 2% relative standard deviation.Liquid sample is in a form of aerosol introduced into plasma, where it is under the influenced of high temperature (7000 K) vaporized, atomized and ionized. Ions are introduced into the MS via a conical lens system (sampling and skimmer cone). There, the ions separate from the stream of argon that maintains the plasma and enter the vacuum region. Electrostatic lenses remove the non-ionized species and direct the flow of ions to the spectral interference removal system. This is made possible by an octapol collision cell with He kinetic energy discrimination and by a reaction cell using gases: NH3, H2, Xe. The ion flow then reaches mass analyser designed as a quadrupole separating the ions based on m / z by a combination of direct and alternating current. ICP-MS is one of the fundamental tools in element specification research, isotopic analysis, elemental composition determination of various materials and water matrices. Rental and access to equipment together with a qualified operator is possible by prior arrangement.

Measuring chain for measuring the noise of road vehicles according to the SPB method
The SPB (Statistical Pass-By Method) measuring equipment is a measuring chain of several devices connected in a system. The measuring chain includes a microphone, a modular precision sound analyzer, 2 photocells for vehicle speed measurements, a laptop computer, a microcontroller, and a humidity and temperature meter.

The measurement method is carried out in accordance with the SIST EN ISO 11819-1 standard. It determines the influence of car tires rolling on road surfaces on the emission of road traffic noise into the environment. The modular precision sound analyzer detects the maximum noise levels of passing vehicles via a microphone standing 7.5 m from the center of the considered driving lane on the test field. Photocells record the passage of vehicles at the measurement point. The speed is determined from the difference in the registration times of each photocell and from the mutual distance between the positions of the photocells, and at the same time the category of the individual vehicle is entered into the computer. After computer processing of the data, a regression curve of the maximum noise levels depending on the speed of the vehicles is determined depending on the type of vehicle.

The measurement method is carried out in accordance with the ISO 11819-2 standard. A dedicated passenger car with standard tires is driven over the test field - typically different road sections. The speed of the car is recorded with a GPS tracker. The modular precision sound analyzer in the car measures the rolling noise of the car tire with two microphones mounted on the microphone holder next to the car wheel. The measuring chain enables the classification of different driving surfaces according to the CPX index, an indicator for the noise level of the driving surface. These data can then be the basis for a model analysis of noise emissions in the vicinity of the considered road sections, or the basis for planning the use of less noisy driving surfaces for the purpose of reducing environmental noise pollution - within the framework of the national operational program for noise protection.
Equipment for environmental noise measurements
The equipment for environmental noise measurements is a measuring chain of several devices connected in a system that includes a microphone, a modular precision sound analyzer, an anemometer, and a humidity and temperature meter.

The modular precision sound analyzer records the level caused by the source in a selected time interval via a microphone that is placed next to the noise source in question. In the analysis, the dynamics of the source are also taken into account, since according to the legislation, the load of most sources must be calculated on an annual average. Since the weather conditions at the time of noise measurements can significantly affect the measurement results, especially at greater distances from the source, they must be properly evaluated and taken into account when evaluating the results.
Brüel & Kjær type 2270 modular precision sound analyzer, Brüel & Kjær type 2260F modular precision sound analyzer, Brüel & Kjær type 4231 sound calibrator, universal anemometer that allows wind measurements even at a height of 10 m AMES UAM 118A and weather multimeter are used for measurements. parameters for temperature, relative humidity and air pressure EXTECH RHT35.

Particle size and shape analyzer SYNC Microtrac MRB
Measurements of the particle size distribution of particulate samples by laser diffraction (LD) have become an indispensable way of obtaining data on powdered samples for quality control of products in the industry and for the characterization of input materials for research and development of new materials. In construction, we most often investigate untreated or treated (potential) input raw materials (of the natural or artificial origin or recycled) for the production of non-hydraulic, hydraulic, and alkali-activated mineral binders, conventional or sustainable building composites (e.g., mortar, concrete), ceramic and insulation materials, pigments, paints, and coatings. The input raw materials for the mentioned products are, e.g., cement, mineral additives (ground granulated blast furnace slag, fly ash, silica fume), calcined clay (e.g., metakaolin), fillers (e.g., limestone dust), industrial waste (e.g., from thermal power plants and heating plants, biomass incineration, paper mills, and steel industry), industrial waste (e.g., red mud from aluminum production) and construction waste from landfills (e.g., mineral wool). These materials have a wide particle size distribution, from nanometers to millimeters, and can be fully characterized with the particle size and shape analyzer SYNC, without the need to combine several methods to achieve a granulation curve of a single material.
The particle size and shape analyzer SYNC is equipped with three lasers that emit red and blue light, allowing the detection of submicron particles and the detection of narrow and multimodal particle distributions in the submicron range. The scattered light on particles is detected by two detectors and evaluated on the basis of an algorithm based on Mie's principle of light scattering. This algorithm creates precise particle size distributions for materials that have particles spherical or angular in shape and for materials that transmit or absorb laser light.
The particle size distribution can be determined on samples dispersed in a liquid medium provided by the FlowSYNC unit or dispersed in the air provided by the TurboSYNC unit.
FlowSYNC - dispersion module for wet measurements
The FlowSYNC unit enables automated filling, de-aerating, pre-circulating, and circulating operation of the sample with a consistency that improves the repeatability of particle size distribution and imaging data. The FlowSYNC can be operated with a wide variety of carrier fluids. In addition to water and alcohol (e.g., ethanol, isopropanol). An in-line ultrasonic probe with variable power disperses agglomerated materials to ensure consistent sample dispersion during measurements.
TurboSYNC - dispersion module for dry measurements
The TurboSYNC unit delivers a properly dispersed sample to the measuring cell of the analyzer, allowing for consistent and repeatable analyses. A moving sample tray introduces the powder into the measurement system. Compressed air and flow conditions allow the operator to achieve optimal dispersion, even for highly agglomerated materials. Volumes can be as small as 0.1 cm3. Larger quantities of powder, if required, can be processed in multiple trays and combined into one measurement record.
Dynamic image analysis
Drawbacks of laser diffraction analyzers are poor resolution for large particles, limited sensitivity for oversize, and the inability to measure particle shape. These downsides of laser diffraction, however, are the strengths of image analysis. Thanks to the unique combination of both techniques, the SYNC particle analyzer provides information that is not available from laser diffraction alone and improves the overall accuracy of particle size measurement. The dynamic image analysis determines essential parameters related to particle morphology and the quality of the dispersion. These fundamental properties can change drastically with no significant differences reported in the laser diffraction size distribution.

Description: The "Dionex Integrion HPIC System" ion chromatography system from Thermo Fisher Scientific is an instrument for qualitative and quantitative analysis of several ions (fluorides, chlorides, sulfates, nitrates, phosphates, etc.) in liquid samples. The ion chromatography (IC) is commonly used for the analysis of pollutants in the environment, ionic compounds in pharmaceuticals, simple carbohydrates in food and beverages, and the determination of important ions in industry.
The chromatographic column is filled with a specific ion exchanger called stationary phase, which allows the separation of ions. The integrated HPIC system (high pressure IC) with high pressure capacity withstands pressures up to 5000 psi (345 bar) and thus enables faster ion separation while maintaining high resolution chemical analyzes. No additional pre-treatment of the eluents is required for the analysis, as the RFIC system ("reagent free IC") provides automatic preparation of these. Eluent generator operates on the basis of electrolysis using special cartridges, where only ultrapure water needs to be added. Eluted ions are detected by a conductometric Dionex CD detector, which measures the electrical conductivity of the solution.
Analyses are possible by prior arrangement. The cost of the investigation depends on the complexity of the analysis.

Rotary tube furnace (Protherm RTR 15/120/1000-3Z) with 3x Omron E5CC controllers and Mullite based Tube (DIN610 quality), 120/100/2100 mm.
Rotary tube furnace enables the production of various materials, such as cement clinker, preparation of light aggregates, thermal activation of materials for mineral additives (e.g. clay calcination), etc. The furnace has the shape of a tube that rotates during operation. The tube is placed at a slight angle so that the material passes smoothly between the areas to the final / target temperature. Furnace has 3 independent heating zones of total length (3x330mm) 1000mm. Each zone can be controlled independently. Maximum operation temperature of furnace is 1500 ° C but since we are currently using Mullite based tube the maximum allowed operating temperature is 1300 ° C. The passage of material between the zones allows rotation (4-20 rpm) and tilt of the tube (up to 15 °). The built-in vibration system ensures easier passage of material between zones. The tube is made of refractory material (mullite tube), which withstands temperature shocks, its diameter is Ø 120 mm and its length approx. 2000 mm. The tube material can be adapted to our needs, they can be made of quartz, ceramic (mullite, SiC) or metal (recrystallized alumina, aluminium, zinc, etc.). The furnace is designed for continuous material processing. It is equipped with an initial dispenser that allows continuous filling and a final output system of the processed material. The furnace is equipped with a simple computer system (Omron E5CC Technical specs), which is on the outer frame of the furnace and allows easy operation of the furnace. Computer system controls the sintering temperature, the heat treatment time of the material, the inclination angle of the tube, the rotation speed of the tube, etc. Dual shell, floor-standing casing allows temperature stability (low external temperatures and high inner temperature). Galvanize coated and powder painted outer casing. Kanthal Globar SiC quality heating elements placed at sides, total of 18 elements. Alarm for preventing over heating of the furnace is installed, protecting the insulation material and the heating elements. The approx. power rating is 15.000 W (connecting voltage; three phase 380/220 V 3-N/PE, 50/60Hz). UPS power supply with the rotation system is recommended against blackouts and for the continuation of rotation until the system is cooled to a stable temperature of environment.
