TSRC Science and Research Equipment Within the project FP7-REGPOT-2008-1-229801 T-Pot funded by the European Union the Faculty of Textile Technology, University of Zagreb has bought the latest scientific and research equipment to the value of almost 400.000 € and installed it at the Department of Textile Chemistry & Ecology. The equipment is located in two laboratories: 1) SEM (Scanning Electron Microscope) Laboratory Equipment purchased under the T-Pot project for microscopy is the following: - FE–SEM MIRA/LMU (Field Emission Scanning Electron Microscope), Tescan - EDX (Energy Dispersive X-Ray) detector (Quantax, Bruker AXS Microanalysis) - Sputter coater SC7620-CF, (Quorum Technologies). This electron microscope allows a detailed characterization of fiber or material, as well as analysis of the resulting changes in the textiles and other substrates. Theoretical magnification of the microscope is 1.000.000 times and besides the standard SE (Secondary Electrons) and BSE (Back-scattered Electrons) detectors, it has additionaly In-Beam detector installed. This detector is allowing high resolution sample image in a very short working distance (WD). The microscope is connected to the EDX device for chemical elements analysis in the shape of dot, line or area (Quantax, Bruker AXS Microanalysis). Since for the electron microscopy the electrical conductivity of the observed sample is a necessary pre-request, the gold/palladium/carbon based sputter coater has been purchased (SC7620-CF Mini, Quorum Technologies). 2) Textile Science Research Laboratory Equipment purchased under the T-Pot project for thermal analysis and FT-IR spectroscopy is the following: DSC 8000, Perkin Elmer device for differential scanning calorimetry measures the heat flow change as a function of temperature. The device records the substance changes due to heating or cooling of samples by endothermic or exothermic reactions regarding the reference determinating indirectly a melting point, crystallization, evaporation, sublimation, glass transition, oxidative degradation, thermal decomposition etc., and representing the results in the shape of curves. DSC 8000 works in inert nitrogen atmosphere and the temperature range from -700C to 7000C. Pyris 1 TGA, Perkin Elmer device measures the sample weight loss in percentage as a function of temperature (and time) during the linear or step heating in the temperature range from 250C to 25000C and in nitrogen/air atmosphere. The results of the TG analysis are represented in the shape of curves, and by this method it is possible to determine a degradation point or sample decomposition. If the device is connected to FT-IR spectrometer (Perkin Elmer Spectrum 100 FT-IR) by means of TG/IR inreface (Perkin Elmer TL 8000) it is possible to analyze organic gass products occured during the heating. Spectrum 100 FT-IR, Perkin Elmer (Fourier Transform Infrared) spectrometer allows three spectroscopic technique. KBr (potassium bromide) technique allows the spectroscopic transmission analysis of very fine ground samples pressed into tablets and ATR (Attenuated Total Reflectance) technique the spectroscopic reflection analysis. The results are represented as spectrogram curves unique for each chemical compound. TG-IR interface, Perkin Elmer TG/IR interface allows the analysis of organic gasses occured during the heating of the sample in TG device (Perkin Elmer Pyris 1 TGA) which are measured by the FT-IR device. 3) Other Science and Research Equipment which dispose at TSRC: Equipment at the site: Savska 16/9 Capital equipment: 1) Differential Scanning Calorimeter - DSC 2) EKA – Electro Kinetic Analyzer 3) FT–IR Fourier Transform Infrared Spectrometer with TG – IR Interface 4) HPLC - Liquid Chromatography Device 5) LOI (Low Oxygen Index) Chamber 6) Scanning Electron Microscope (FE SEM) 7) Spectrophotometer Cary 50 Solascreen 8) Spectrophotometer Microflash 9) Spectrophotometer Pye Unicam 10) Spectrophotometer Specol SV 11) Spectrophotometer Spectraflash SF 300 12) Spectrophotometer Spectraflash SF 600+CV UV 13) Thermogravimetric Analyzer - TGA 14) MCC – Microscale Combustion Calorimeter Small to medium sized equipment: 2) Apparatus for wet finishing and dyeing 3) Autoclave 5) Bundesmann water repellency tester 6) Fixotest 7) Instrument for determination of vertical burning of textiles 8) Jigger 9) Linitest 10) Padder 11) pH meter 15) Sputtering device - SC7620 17) Sweating Guarded Hotplate (Skin Model) 18) Tensile tester for yarn and fabric 19) Viscosimeter 20) Washing machine 21) Water quality analysis – Nanocolor photometer Equipment at the site: Prilaz b.

Znanstvena i istraživačka oprema TSRC-a U sklopu projekta FP7-REGPOT-2008-1-229801 T-Pot financiranog od Europske Unije Tekstilno-tehnološki fakultet Sveučilišta u Zagrebu nabavio je najnoviju znanstveno-istraživačku opremu u vrijednosti od gotovo 400.000 € instaliranu na Zavodu za tekstilno-kemijsku tehnologiju i ekologiju. Oprema je smještena u dva laboratorija: Oprema nabavljena putem T-pot projekta za mikroskopiju je slijedeća: - FE–SEM MIRA/LMU (Field Emission Scanning Electron Microscope), Tescan - EDX (Energy Dispersive X-Ray) detektor (Quantax, Bruker AXS Microanalysis) - Naparivač SC7620-CF Mini, (Quorum Technologies). Ovaj elektronski mikroskop omogućuje detaljnu karakterizaciju vlakana ili materijala, kao i analize nastalih promjena na tekstilnim i ostalim supstratima. Teoretsko povećanje ovog mikroskopa je 1.000.000 puta, a uz standardni SE (Secondary Electrons) i BSE (Back-scattered Electrons) detektor, posjeduje i In-Beam detektor koji omogućuje promatranje uzorka na vrlo kratkoj radnoj udaljenosti uz visoku razlučivost. Mikroskop je povezan sa EDX detektorom za kemijsku analizu elemenata i to u obliku točke, linije ili površine na uzorku (Quantax, Bruker AXS Microanalysis). Kako je za elektronsku mikroskopiju nužan preduvjet elektrovodljivost promatranog uzorka, nabavljen je i naparivač na bazi zlata, paladija i ugljika koji naslojava nevodljive uzorke elektrovodljivim česticama (SC7620-CF Mini, Quorum Technologies). Textile Science Research Laboratorij Oprema nabavljena putem T-pot projekta za termičke analize i FT-IR spektroskopiju je slijedeća: DSC 8000, Perkin Elmer uređaj za diferencijalnu skenirajuću kalorimetriju koji mjeri promjenu toplinskog toka kao funkciju temperature. Ovaj uređaj bilježi promjene stanja uslijed zagrijavanja ili hlađenja uzorka kod endotermnih ili egzotermnih reakcija u odnosu na referentni uzorak čime posredno utvrđuje točku tališta, kristalizacije, isparavanja, sublimacije, staklišta, oksidativne degradacije, termičke dekompozicije i dr., a rezultate prikazuje u obliku krivulja. DSC 800 radi u inertnoj atmosferi dušika i u temperaturnom rasponu od -700C do 7000C. Pyris 1 TGA, Perkin Elmer uređaj za termogravimetrijsku analizu mjeri gubitak mase uzorka u postocima kao funkciju temperature (i vremena) tijekom linearnog ili stepenastog zagrijavanja u određenom temperaturnom rasponu (250C – 15000C) i u određenoj atmosferi (dušik, zrak). Rezultati TG analize prikazani su u obliku krivulja, a ovom metodom moguće je odrediti točku degradacije, odnosno dekompozicije uzorka. Ukoliko je uređaj spojen TG/IR sučeljem (Perkin Elmer TL 8000) na FT-IR spektrometar (Perkin Elmer Spectrum 100 FT-IR) moguće je analizirati i plinovite organske produkte nastale zagrijavanje uzorka. Spectrum 100 FT-IR, Perkin Elmer (Fourier Transform Infrared) spektrometar, omogućuje tri tehnike spektroskopije uzoraka. KBr (kalijbromid) tehnikom omogućuje spektroskopsku analizu transmisije fino mljevenih uzoraka prešanih u obliku tanke tablete, a ATR (Attenuated Total Reflectance) tehnikom spektroskopsku analizu putem refleksije. Dobiveni podaci prikazani su u obliku spektrograma jedinstvenog za svaki spoj. TG-IR interface, Perkin Elmer. Preko TG-IR sučelja omogućuje se analizu organskih plinova nastalih zagrijavanjem uzoraka u TG uređaju (Perkin Elmer Pyris 1 TGA), koja se prati putem FT-IR spektrometra.
