Service description

JASCO 4700LE spectrophotometer. Energy range: 350-7800 cm-1. The attenuated total reflectance accessory (ATR) is used to measure samples of powder and solids such as films or different substrates, as well as samples in liquid. Transmission accessory for transparent or translucent samples is also available. In this case, the powder samples can also be measured by making KBr pellets. This equipment works in a self-service regime for internal users, who have been previously trained by the technician. However, for external users the assistance of the service technician is needed.

Service description

Vertex 70 is a fully digital FT-IR spectrometer designed for the signal adquisition from the far IR region (700cm-1) to the visible región (7000 cm-1), with its pre-aligned optical components and permanently aligned RockSolid interferometer, range change is easy and maintenance free. This equipment can do two types of measures over the samples: absorbance and reflexion. Also, the vertex 70 is equiped with two detectors (MTC and TGS). The PMA 50 was specifically developed for polarization modulated IR-spectroscopy. Besides methods based on linear dichroism such as VCD, it also enables the investigation of circular dichroism.

Service description

Fourier Transform Infrared Spectroscopy (FTIR) is one of the most versatile analytical techniques that allows rapid identification of functional groups in the molecular structure of substances in the gaseous, liquid or solid state. Two different spectrophotometers, Nicolet Magna IR 8700 and IR 560, equipped with two -DTGS and MCTA- detectors and OMNIC software are available in our laboratory. The different accessories allows to obtain the spectra in the transmission mode, attenuated total reflectance (ATR) and diffuse reflectance (DRIFT) of the samples in solid or liquid form. Diffuse Reflectance Spectra-Tech Collector and Smart Collector for high sensitivity analysis of powder samples. Smart Orbit diamond crystal suitable for the direct analysis of liquid or solid samples (powders, plaques, fibers, coatings, films, ...).

Service description

The Service FT-IR is a support unit that provides a wide range of characterization techniques for all type of materials, including the materials characterization by FTIR spectroscopy. This laboratory supports to ICB researches, OPIS and universities, as well as companies and individuals. For this porpuse, the Service is equipped VERTEX70 spectrofotometer (Bruker). The task of this service is performing the materials characterization FTIR spectroscopy, as well as the development of new analytical methods, with the highest technical accuracy, working in a responsible and transparent way to ensure maximum reliability of the results. . The Service has highly experienced technical staff to carry out the analysis under the conditions required. In addition, it offers technical advice and interpretation of results. To perform an analysis, users are required to complete an application form specifying the conditions to carry out the analysis. Samples and application form must be delivered to the service responsible for registration. External users are sent an offer for acceptance that must be enclosed too. Infrared spectroscopy FTIR analysis are carried out in a Vertex 70 spectrometer by Bruker. The spectrometer is able to work in FIR, MIR and NIR and it is provided with optical microscope with appropiated lenses for visible and infrarred radiation. It allows the acquisition of micro-FTIR spectra in transmission and reflexion mode for solid samples

Service description

Both the solid samples in the form of powders or fibers, and the liquid samples will come in vials that the user will bring. Those interested in performing Picnometry tests should fill in the corresponding form. ATR The minimum amount of sample is necessary to cover the diamond. It is not necessary to prepare the sample beforehand, except in the case of powder solids with a very large particle size, in which case it is necessary to grind them. KRS5 The minimum amount of sample is necessary to form a thin film between the crystals of KRS5 (normally corresponds to a drop of sample). No pre-preparation of the sample is necessary. It is important to know that there are liquids that can not be measured by this method because they attack KRS5 crystals like some acids, acetone ... KBR Solid samples, 0.5 mg of sample <50 ¿m in size per 300 mg of KBr (amount needed for 1 tablet). DRIFT Solid samples, 300 mg of sample <50 ¿m in size (amount necessary for 1 previous measurement).

Caracterizacion molecular FTIR-ATR	euro / muestra	75.04 €	82.19 €

Service description

Using the 4100 FT-IR Spectrometer from JASCO, by recording transmitted or reflected light after interacting with the sample, a spectrum is obtained that serves as a characteristic "molecular fingerprint" and can be used to identify organic and inorganic samples. It is possible to work in Attenuated Total Reflection (ATR) mode (Pike module with ZnSe crystal) for liquids, films or thin powders, or in transmission mode for thin and semi-transparent films in visible light. The available configuration allows recording spectra in a wavenumber range of 4000 - 600 cm-1. The acquired spectra can be compared with spectra recorded in spectral reference libraries.
