This series of four thermal analysis webinars is designed to educate the user on the basics of measurement, calibration, maintenance, and experimental design, as it relates to Thermogravimetric Analysis. Each webinar is about 60 minutes long, and will have a 10-minute question and answer session at the end. A Certificate of Completion will be awarded to viewers who watch all 4 webinars in this series.
An Introduction to Thermogravimetry
In the first episode of our Practical Approach to Thermal Analysis TGA Webinar Series, Dr. Kadine Mohomed gives an overview of Thermogravimetry and the TGA instrument.
Advanced Separation & Resolution Techniques
Yash Adhia explores methods for improving resolution of complex TGA profiles and introduces HiRes® TGA and Stepwise Isothermal TGA in episode two of our Practical Approach to Thermal Analysis TGA Webinar Series.
Measuring Kinetics Using TGA
This third episode in our Practical Approach to Thermal Analysis TGA Webinar Series discusses TGA methods for determining decomposition Activation Energy, presented by Andre Levchenko.
Evolved Gas Analysis: Mass Spectrometry TGA
James Browne introduces the coupled techniques of Thermogravimetric Analysis and Mass Spectrometry in the final episode of our Practical Approach to Thermal Analysis TGA Webinar Series. Special guest Jacques LaBrosse of MKS Instruments joins us to provide his expertise.
Evolved Gas Analysis: TGA/FTIR
Interested in detecting and identifying the presence of residual solvents in your formulation? Would you like to determine the thermal decomposition mechanism of your material? Thermogravimetric analysis (TGA) directly measures weight change of a material as it is heated over a temperature range in a controlled atmosphere. If observing a weight loss, then it may be accompanied by off-gasses associated with volatilization of solvents or degradation of the material.
This series of five thermal analysis webinars is designed to educate the user on the basics of measurement, calibration, maintenance, and experimental design, as it relates to Differential Scanning Calorimetry. Each webinar is about 60 minutes long, and will have a 10-minute question and answer session at the end. A Certificate of Completion will be awarded to viewers who watch all 5 webinars in this series.
An Introduction to Differential Scanning Calorimetry (DSC)
In the first of our five-episode Practical Approach Webinar Series, Dr. Kadine Mohomed introduces a few of the key concepts to getting started with DSC analysis.
A Step-by-Step Guide to DSC Calibration and Verification
Episode Two of this Practical Approach Webinar Series guides the user on DSC calibration, and verification of heat flow baselines, presented by Dr. Kadine Mohomed.
Optimization of Experimental Conditions for Common DSC Applications
In Episode Three of our Practical Approach Webinar Series, Dr. Kadine Mohomed will teach the user about approaching test method development for some common DSC applications.
Strategies for Data Analysis
Yash Adhia explores how to analyze your collected data in Episode Four of our five-part Practical Approach Webinar Series.
An Introduction to Modulated DSC
In the Fifth and final Episode in our Practical Approach Webinar Series, James Browne leads the discussion on an introductory overview of Modulated DSC (MDSC).
About The Speakers
