Introduction:

Institution’s Innovation Council (IIC), Lloyd Institute of Management and Technology organized a “Hands on Training session on Malvern Zetasizer Advance Series”. It was delivered by Mr. Amit Kumar and Dr. Dipanjan Giri, both being Application Specialist at Malvern Application Laboratory on 6 Feb 2025.

Venue: Centre for Training & Placement Cell (For Theoretical session), Research Lab (For Practical session)

Duration: One Day, 9:30 - 4:30 PM

A workshop on the handling and operation of the Zetasizer was conducted to provide participants with practical knowledge and hands-on experience in using this sophisticated instrument. The Zetasizer is a crucial tool for measuring particle size, zeta potential in various scientific fields, including material science, chemistry, and biopharmaceutical research. The aim of the workshop was to familiarize attendees with the principles, applications, and troubleshooting techniques associated with the Zetasizer.

The Speakers Mr. Amit Kumar has more than 15 years of experience as a specialist for couple of technique, DLS, ELS, Laser diffraction, XRF, etc. in Malvern’s excellence laboratory where he traines users, or troubleshoots applications oriented issues and Dr. Dipanjan Giri is M.Sc and PhD in polymer Chemistry from IIT Kharagpur. He embarked on IOE postdoctoral fellowship at IISc Bangalore. Following the completion of his postdoc, Dipanjan resumed his corporate career at Malvern Panalytical’s application Lab, Aimil Ltd, New Delhi.

Mr. Amit Kumar briefed in his theoretical session about the fundamental principles behind dynamic light scattering (DLS) and electrophoretic light scattering (ELS). He also discussed common challenges and troubleshooting methods. Participants engaged actively in Q&A sessions.

The Practical session was demonstrated by Dr. Dipanjan Giri. He very well explained about:

• Instrument Setup and Calibration
• Sample Preparation Techniques
• Measurement of Particle Size and Zeta Potential
• Data Interpretation and Analysis

Attendees had the opportunity to operate the Zetasizer, gaining confidence in handling the instrument and interpreting results.

Experts provided individualized support, addressing specific queries and ensuring that each participant left the session with a clear understanding of the Zetasizer’s functionalities.

The hands-on session concluded with a recap of best practices and a Q&A round where participants discussed their experiences and clarified any remaining doubts. By the end of this session, attendees were confident in independently operating the Zetasizer, preparing accurate samples, and interpreting complex data, significantly enhancing their research capabilities.

The evaluation was done by asking the questions related to workshop and active involvement during hands-on sessions.
