Powder X-ray diffractometer STOE StadiP

Location: B360

Our powder X-ray diffractometer (XRD) consists of two individual instruments capable of X-ray scattering analysis using both Cu (λ=1.54 Å) and Ag radiation (λ=0.56 Å) in transmission geometry. XRD can be used to analyze both crystalline and amorphous samples by measuring either conventional diffraction patterns or high Q-range total scattering patterns for pair distribution function (PDF) analysis. Measurements can be performed in room or elevated temperature up to 800 ⁰C.

FTIR spectrometer ThermoFisher Nicolet iS5

Location: C360

The IR spectrometer is used for fast routine IR spectra acquisition in the 4000-400 cm^-1 range with a maximum resolution of 0.9 cm^-1, although in practice higher resolution than 4 cm^-1 is seldom necessary. IR spectra can be measured on both liquid and solid samples. The measurements are usually performed using the diamond attenuated total reflectance (ATR) accessory that allows to obtain a spectra in a few minutes with no sample preparation of very small (<1 mg) sample quantities. Measurements of KBr pellets or similar samples in transmission geometry are also possible. List of accessories available:

• iD7 diamond ATR (most commonly used)
• iD1 transmission
• iD1 in-situ probe with Si ATR tip
• iD Foundation multi-bounce ATR with either ZnSe or Ge prism

THEMYS ONE+ TG-DTA/DSC Analyzer

The THEMYS ONE+ is a thermal analysis platform with the following features:

• equipped with an auto-sampler with a 32-position carousel
• rods available: TGA rod with built-in S-type thermocouple and DSC rod with P-type thermocouple
• measuring ranges: +/- 1000 mg or +/- 200 mg
• furnace configuration up to 1150°C, with temperature scanning rate from 0.01 to 100 °C/min
• measurements can be done under nitrogen gas, argon, and compressed air

Micromeritics Gemini VII gas sorption analyzer

Location: C358

The gas sorption analyzer is used to determine surface area and pore volume of solid materials. Measurements are usually done using nitrogen gas at the boiling point of nitrogen (77 K). The surface area of the material is determined by measuring the amount of gas sorbed onto the surfaces (cm³ N₂ STP per g solid) at increasing pressures (adsorption) or decreasing pressures (desorption). The obtained N₂ sorption isotherm at varying pressures can be used to distinguish between varying surfaces, outer surfaces, macro-, meso- and microporous surfaces. The BET (Brunauer, Emmett and Teller) theory is commonly used to determine the specific surface area of most solid materials. For porous materials with very narrow micropores (<2 nm), other adsorbent gases need to be used such as argon at 87 K for zeolites and MOFs, and carbon dioxide at 273 K for carbonaceous materials (i.e., activated carbon, nano- and mesoporous carbons).

Thermo Scientific™ Gallery™ Plus discrete analyzer

Location: C166

The Thermo Scientific™ Gallery™ Plus discrete analyzer enables the simultaneous analysis of multiple analytes using its discrete cell technology. This fully automated, high-capacity system delivers quick, reliable results and features an integrated platform that supports photometric (colorimetric and enzymatic with wavalength range from 340 nm to 880 nm) analytical method. With the ability to process 108 samples and 42 reagents on separate sample and reagent disks, and to perform dilutions and repeat analyses automatically, the Gallery Plus can carry out up to 350 tests per hour. 

UV-Visible spectrophotometer ThermoFisher Evolution 220

Location: C164

The UV-Visible (UV/VIS) spectrophotometer measures absorption of light in 190-1100 nm range. Measurements are possible in either ex-situ mode in cuvettes or in-situ using an external probe. The instrument is mostly used for the determination of elemental concentrations (e.g., Fe2+, As, Si, P) using well-established colorimetric methods. In addition, the spectrophotometer can also be used for the in situ and real-time monitoring of the nucleation, crystallization and growth of minerals, and is equipped with Single Cell Peltier System for temperature control and sample stirring.

VASCO KIN particle size analyzer

Location: C164

The VASCO KIN is an equipment that uses optical fiber dynamic light scattering (DLS) to characterize submicron particles in liquid dispersions. It can measure particles ranging from 0.5 nm to 10 µm. There are several optical head accessories available that enable measurements in diverse sample set-ups: in situ, in line (milli-fluidic head), in cuvette (thermalized/temperature-controlled head).

Particlemetrix STABINO particle charge mapping

Location: C358

This instrument measures the size and ζ-potential of suspended particles, with an error of 2%. The volume of the measuring cell is 10 mL and the detected size range is between 0.3 nm - 300 μm. The addition of titrants is possible and controlled via two tanks by delivering solutions to the suspension.
