Micromeritics AccuPyc II 1340 Helium pycnometer

The gas pycnometer measures the true, absolute and skeletal densities of powdered solids. The device works on the basis of the gas law, using inert gases such as helium, nitrogen or air as the displacement medium. In our case, the volume of the sample is determined by the change in pressure of He in a cell of a given volume. From the mass data (weighing), the pycnometer calculates the true density.  

Micromeritics GeoPyc 1365 density meter

The GeoPyc density meter automatically determines the volume and density of a solid sample. During analysis, the volume of a fine, dry, liquid powder with a high flow rate, called DryFlo, is measured first. The sample is then immersed in the DryFlo medium and the volume of the sample is measured on a displacement basis. Since DryFlo takes into account the surface irregularities of the material, achieves a tight packing around the sample under investigation and does not enter the smallest pores (with entrance diameters smaller than about 25 microns), we can measure the volume, density and porosity of irregularly shaped samples or even multiple pieces. The analysis is fast and quiet, and non-destructive for the sample.

The software-controlled autosampler (ASC-7000) in the AA-7000 supports flame and graphite furnace (electrothermal) techniques and has a capacity of 60 samples. It has a built-in flushing mechanism to prevent contamination between two samples.

Microwave system for splits ETHOS LEAN and ETHOS EASY (Milestone)

Because microwave decomposition systems provide an efficient sample preparation method for analytical techniques such as atomic absorption spectroscopy (AAS), ICP-OES, and ICP-MS, microwave decomposition is one of the most commonly used sample preparation techniques. In microwave decomposition systems, solid samples (metals, food, soil, medicine and others) are completely decomposed at elevated temperature and pressure. Solid samples are (mostly) converted into liquids with the help of acids and oxidants. Decomposition time depends on the sample, but usually does not take more than 60 minutes. In our laboratory, we use a microwave acid decomposition system designed for closed-vessel decompositions, which allows the use of different combinations of acids and full control over several reaction parameters.

Laboratory rotavapor - Rotavapor® R-100 (Büchi)

A rotary evaporator is a device used in laboratories to efficiently evaporate solvents from samples. Evaporation of the solvent takes place with the help of a decrease in pressure, which causes a decrease in the boiling point of the solvent and its efficient evaporation at moderate temperatures. It is designed for reliable and flexible rotavaping that covers most needs in evaporation applications. Rotavapor® R-100 enables the rotation speed of the flask in the heating bath from 20 to 280 rpm, and it is also possible to control the temperature range from 20 to 95 °C.

Kratos Supra+ enables automatic angle-resolved measurements, sample heating and cooling, and depth profiling of organic substances with GCIB (gas cluster ion beam) technology and depth profiling of inorganic substances with monatomic Ar+.

Profilometer DektaXT (Bruker)

A contact profilometer is an instrument that allows determining the profile of a sample by sliding a diamond tip over the surface and recording the deviation from the reference plane of the sample. In this way, we obtain data on the roughness of the surface, the 3D profile of the surface and also the thickness of the surface layer. The device is used to examine various types of solid materials with a surface area of ​​up to 10 cm in the x-direction and up to 10 cm in the y-direction. The latter complements atomic force microscopy (AFM) measurements, where we are limited to 120 micrometers in the x-direction and 120 microns in the y-direction. Compared to AFM, the profilometer allows determining the topography of samples with a much larger height difference, but its spatial resolution (compared to the AFM instrument) is lower. The DektakXT profilometer from Bruker is equipped with 2 µm, 5 µm and 12 µm diameter tips.

Gas chromatograph with mass selective detector and flame ionization detector (GC-MS) - GC-MS, GCMS-QP2020 NX (Shimadzu)

In the column, the sample is separated into different components, whereby the components are eluted from the column after a certain time. It is equipped with a mass selective (MS) detector and a flame ionization detector (FID). The introduction of the sample into the gas chromatograph can be carried out using the headspace sampling technique, injection of liquid samples or solid phase microextraction (SPME). The instrument is equipped with an automatic sampler capable of analyzing 162 liquid and 45 gaseous samples. He has two English. split/splitless injector, one for the MS-system and the other for the FID-system, which enables the simultaneous installation of two chromatographic columns.

Ion chromatograph (IC) - HIC-ESP (Shimadzu)

Ion chromatography (IC) is used to determine cations and anions. Based on the interactions of the charged particles of the analyte with the oppositely charged functional groups of the stationary phase, different ions can be separated. The IC consists of an autosampler, an oven, a solvent feed pump, a suppressor, a degasser, and a detector. The use of an autosampler enables very fast injection, the inert pump system optimizes solvent delivery control, and the suppressor reduces the background signal from the eluent.
