Spectroscopic Techniques Laboratory

About

The ICMAB Spectroscopy Service was created with the main objective to provide centralised equipments and installations mainly to the research ICMAB groups though the service is also opened to external users. The priority of this service is to offer the highest levels of technology and quality to satisfy the requirements of the research lines currently underway in our institute. The currently equipments available are: EPR, UV-Vis-NIR, FT-IR and RAMAN. For EPR and RAMAN equipments highly qualified technical staff is employed. The rest of the equipments are mainly used on a self-service regime. Three types of spectroscopy techniques have been carried out: a) Molecular spectroscopy: The systems available in our laboratory allow analytical and physic-chemical studies of organic and inorganic molecules (in solid or liquid state) in the ultraviolet, visible and infrared energy range. b) Electron Paramagnetic Resonance: The EPR allows to detect and study transient and stable paramagnetic species such as free radicals, over a very wide range of temperatures.

Equipment

FTIR

Spectrophotometer Jasco 4700. Energy range: 300-7800 cm-1.  The Service is provided with a Attenuated Total Reflectance accessory (ATR) for powder samples, films, polymers, liquids, etc. Powder samples can also be measured making KBr pellets.
This equipment is of self-service management for internal users, who have been previously trained by the technicians. However, the technicians are needed for the external users

UV-Vis-NIR

There are two double beam UV-Vis-NIR spectrophotometer, a Varian Cary 5 and a Varian Cary 5000 with operational range of 190-3300 nm and also a Shimadzu UV-Vis 1700 spectrophotometer with operational range of 200-800 nm.

Liquid samples 
can be measured in absorbance or transmittance mode mainly using 1 cm or 1 mm quartz cuvettes. The three equipments are of self-service management for internal users, who have been previously trained by the technicians. However, the technicians are needed for the external users.

For solid samples it is available a Diffuse Reflectance Sphere DRA-2500 accessory in the UV-Vis-NIR Varian Cary 5000 spectrophotometer, with operational range of 190-3300 nm. Solid samples can be measured mainly in reflectance or transmittance mode.

A qualified technician is always needed for running the DRA-2500 accessory.

EPR

Bruker ELEXYS E500 X band EPR spectrometer equipped with a variable temperature unit, a field frequency (F/F) lock accessory and built in NMR Gaussmeter. There are different cavities for the different measurements needed. A qualified technician is always needed for running this equipment.

Request Service

INTERNAL USERS
First contact with the Service Technicians Vega Lloveras (This email address is being protected from spambots. You need JavaScript enabled to view it., ext. 300, 311). They will train the users to manage the equipment by themselves because it works in a self-service regime for internal users.
All users must register in the database registration of the equipment every time they use it, pointing out the time they have spent doing the measurement, the group's IP and the project's number.

EXTERNAL USERS
First contact with the Service Technicians Vega Lloveras (This email address is being protected from spambots. You need JavaScript enabled to view it., ext. 300, 311) in order to arrange the details of the measurements. At the same time, a service form must be filled in. Every equipment has its own service form. There exists the possibility of working with the apparatus in a self-service regime.
In addition to this, all users must also register in the database of the equipment every time they use it.

FT-IR

Follow the general procedure

UV-Vis-NIR

1. Liquid measurements.
Follow the general procedure.
2. Solid measurements using Diffuse Reflectance Sphere (DRA-2500) accessory.
The technicians are always needed for running the DRA-2500 accessory, for internal as well as for external users. Contact with them (This email address is being protected from spambots. You need JavaScript enabled to view it., ext. 300, 311) in order to arrange the details of the measurements.
