Poornaprajna Analytical Center

 
Availability of Central Instrument Facility for Academic/Industrial Researchers

Poornaprajna Institute of Scientific Research (PPISR) has established a testing facility for all researchers from academic institutions and industries, to characterize their samples. Interested individuals can analyze their samples under the guidance of a PPISR staff. PPISR has procured several analytical instruments that are vital for the faculty and students to pursue advanced research in basic and applied sciences.  The Analytical Facility has several sophisticated instruments namely Powder X-ray Diffractometer, Surface Area Analyzer, Temperature Program desorption (TPD)   Analyzer, Atomic Absorption Spectroscopy (AAS), Fourier Transform Infrared Spectroscopy (FTIR), Ultra Violet–Visible Spectroscopy (UV-VIS), and Fluorescence Spectrophotometer.

The following instruments are available at the PAC for external users:

 

1. Fourier Transform Infrared Spectroscopy (FTIR)
The Bruker-alpha FTIR spectrophotometer is a compact instrument and measures the infrared spectrum, which represents the molecular absorption and transmission of a sample.

Specifications:
Spectral range 500-4000 cm-1 with scan rate of 32
Attenuated Total Reflectance available
Solid, liquid and gel samples can be analyzed without making pellets
2. Fluorescence Spectrophotometer
The Varian Cary Eclipse Fluorescence Spectrophotometer is a compact instrument and measures the fluorescence, phosphorescence, chemi/bio-luminescence, and time resolved phosphorescence.

Specifications:
Spectral range UV-Vis. Xenon flash lamp technology with room light immunity and high sensitivity.

Both solid and liquid samples can be analyzed.
  3. Ultra Violet – Visible Spectroscopy (UV-VIS)
The UV-Visible spectrophotometer from Perkin Elemer can be routinely used in analytical chemistryfor the quantitative determination of different analytes such as transition metal ions, highly conjugated organic compounds, and biological macromolecules.

Specifications:
deuterium lamp source for UV region and tungsten halogen lamp for Visible region
Both solid(only thin films) and liquid samples can be analyzed by UV-Vis
Solid samples in the form of thin films can be analyzed
Absorbance, Transmittance, Diffused Reflectance for liquids and Absorbance, Transmittance for solids can be measured
4. Temperature Program desorption (TPD) Analyzer
BEL’s new fully-automated catalyst analyzer, enables comprehensive catalyst study by using the techniques;
1) Temperature programmed desorption (TPD)
2) Temperature programmed reduction (TPR)
BELCAT II will be the strong tool for the catalyst evaluation.

 

Typical Applications
Acidity study of cracking catalyst by ammonia or pyridine TPD. Basicity study of solid base catalyst. etc…
BEL Sorp II, Japan

5. Surface Area Analyzer with pore size distribution etc
BELSORP-miniII is a compact, volumetric adsorption measurement instrument used for specific surface area and pore distribution measurement. Up to 3 samples can be measured simultaneously and independently with dedicated software, which makes operation of the instrument straightforward.

Specifications
Measurement principle: Volumetric gas adsorption method +AFSM
Adsorptive: N2, Ar, CO2, H2 and other non-corrosive gases
Analysis port: High accuracy mode: 3 ports, Standard mode: 2 ports.
Specific surface area: 0.01m2/g and above (N2/77K, depends on sample density)
Pore size distribution: 0.35 – 200 nm in pore diameter

6. TGA/DTA (Simultaneous Thermal Analyzer)
STA 6000 (Perkin Elmer) features the innovative SaTurnA Sensor for high quality, simultaneous Thermo-Gravimetric (TG) and DTA/DSC measurements.
This advanced sensor is optimized to achieve flat DTA baselines and high sensitivity. Because both sample and reference are measured simultaneously, we can be sure of the integrity of our analysis. Temperature max: Up to 850 °C, Temperature accuracy = ±0.5 °C Balance precision ±0.02%.


Specifications
