Central Instrumentation Facility

Ravenshaw University has a single-point instrumentation facility with free access for all faculty and research scholars. Every high- end instrument installed in CIF is assigned to a faculty member who specialises in a certain field of research and operates a laboratory in the central facility. CIF also provides access to researchers from other academic institutions, at a nominal fee charged towards the maintenance of equipment and basic chemicals and materials used in the lab.

The GC-MS & GC lab provides facilities for Structural elucidation of organic compounds, study of fragmentation process, Molar mass and structural analysis of small molecules, Flavors, Fragrances, Forensic, Pharmaceuticals, Organic, Chemical, Petrochemicals samples. This facility was created in 2016 out of “FIST” grant of DST, Govt. of India. Since 2016 the Department of Chemistry has been providing GC and GC-MS lab facilities. The lab serves the chemistry faculty as well as other faculties in Ravenshaw. In addition, the lab gives consultation and services to other institutions and agencies like the forensic laboratory of Odisha.

Sample Requirement

5-10 mg of sample in solid or in liquid form

The FE-SEM facility is dedicated for imaging nano-scale materials. This facility was created in 2019 out of Rashtriya Uchchatar Shiksha Abhiyan (RUSA) grant, Ministry of Higher Education, Government of India, which is a Centrally Sponsored Scheme (CSS), aims at providing strategic funding to eligible state higher educational institutions. This facility is for carrying out research and consultancy in Biology, Chemistry, Geology and Physics to observe structures that may be as small as 1 nanometer (= billion of a millimeter) for morphological, chemical and analytical study of materials. The Energy dispersive spectroscopy (EDS) option is available for elemental analysis of nano or microstructures. The instrument is located in New Academic Block-I, Ground Floor.

Our Laboratory is equipped with a Zeiss make GeminiSEM 300 that uses a field-emission gun (FEG) electron source and can be switched between three vacuum modes enabling the investigation of conductive, non-conductive and high-vacuum incompatible materials. It offers nanometer resolution and a high signal to noise ratio in regular high vacuum. The EDS consists of a 30 mm2 SDD detector which enables detection of elements under high resolution.

FE-SEM

Performance

Samples can be studied in pressures up to 5 Torr. Equipped with SE, Inlens and EDS detectors. Manual user interface EDS with 30 mm2 SDD detector which can be used in three modes: point & ID, analyzer and mapping

Resolution

0.6 nm

Applications

Surface morphology of all kinds of conductive and non-conductive samples including nano to micro scale structures, films, ceramics etc. can be analysed. Elemental detection and orientation mapping can be done by EDS.

Sample Specifications

Conductive and non-conductive solid samples can be analyzed. 

Non-conductive samples can be analyzed under low vacuum mode or must be sputter coated either with gold-palladium or carbon for high vacuum mode.

Sample requirement for analysis

5 mg for powder sample and 1X1 cm2 for films

Magnification

25X to approx 20,00000X depending on the nature of the sample

Voltage

0.2 kV to 30 kV

Points to be noted

Samples should not be toxic, reactive or volatile in nature

Sample should be well dispersed and vacuum dried

The instrument is located at New Academic Block-I, Ground Floor.

Fourier Transform Infrared Spectroscopy (FT-IR)

Fourier Transform Infrared Spectroscopy, also known as FTIR Analysis or FTIR Spectroscopy, is an analytical technique used to identify organic, polymeric, and, in some cases, inorganic materials. The FTIR analysis method uses infrared light to scan test samples and observe chemical properties. FTIR analysis identifies unique chemical bonds in a molecule and produces distinctive molecular fingerprints that can be used to screen samples for many different components. The department of Chemistry is equipped with a

Polarimeters measure the optical activity of an optically active substances by passing polarized light through a substance and observing the angle of light emitted. Our laboratory employs digital polarimeter AUTOPAUL IV to measure the rotation of plane polarized light. This polarimeters perform readings automatically and give instantaneous results.
