3 Fourier Transform Infrared Spectrophotometer FTIR-480, Jasco
Applications: structure analysis; purity examinations; quantitative analysis; identification of unknown compounds: liquids, semi-liquids and flexible solids; biological materials study; with HATR plates ZnSe highly absorbing substances can be analyzed (polymers, rubber, fibers, etc); Specifications: Wavelength range: 360 to 7800 cm-1; Resolution range: 0.5;0.9;2;4;8;16 cm-1 Accessories: 1) MIRacleTM single reflection HATR (horisontal ATR, Pike technologies) with 2 mm round crystal ZnSe. 2) &3) HATR plates in “through” and “flat” configurations. “Through” – for liquid, powder, or paste, good for volatile compounds; “flat” – for the analysis of solid materials including polymer and film samples. For more info:

4 Spectropolarimeter J-810, Jasco
Measures the circular dichroism (CD) and optical rotary dispersion (ORD) of the sample. Applications: Allows to verify the chirality of molecules or compounds; to estimate fractions of each different conformation in protein structure; the conformational changes of molecules with temperature/and pH can be studied. Useful for verifying that the protein is in its native conformation. Protein folding studies. Purity testing of optically active substances. Specifications Light source: 150W Xe arc lamp (N2 cooled) Wavelength range: 163 ~ 900 nm Accessories: Peltier type temperature controller Jasco PFD-425S Automated pH titrator Jasco ATS 429S

6 CAM 200 (KSV) CCD Camera CAM 200 is a video camera based fully computer controlled contact angle meter. Applications: Contact angle measurements; Surface free energy measurements; Absorption and wetting; Surface/interfacial tension For more info:

7 Variable-angle spectroscopic ellipsometer GES 5 (Sopra Inc)
Spectroscopic ellipsometry (SE) is a non-contact, non-destructive optical technique. Applications: measures material refractive indices; layer thicknesses of thin film layers on flat substrates; up to 7 layers can be analyzed in terms of thickness and optical characteristics for each layer. Features: Thickness measured: from monoatomic to several microns thick. The beam size: 1 mm2 and 10 mm2; The variable angles: from 7º to 90º with variable +/- 0.01º; spectral range from 200 nm to 800 nm For more info:

8 Flame atomic absorption spectrometer - AAnalyst 200, Perkin Elmer
Applications: for determining very precisely the concentration of a particular element in a liquid sample. Can detect from 1 to 1000 µg/L. For each element, the specific lamp is required. Currently, Ca lamp is available. The list of lamps/elements for analysis on AAnalyst 200 can be found on https://www.vwrcanlab.com/programs/equipment/pdf/Model%20AAnalyst%20200%20Spectrometers.pdf Hollow cathode lamps (HCLs) and electrodeless discharge lamps (EDLs). EDLs provide much higher light output and longer lifetime when compared to conventional HCLs.

9 BiAcoreX SPR spectrometer
