Pyrolysis Gas Chromatography/Mass Spectrometry

• Single Shot Pyrolysis-GC-MS: It runs on a single temperature, which is then rapidly increased at a rate of 20 msec to break bonds.
• Double Shot Pyrolysis: It runs both at high and low temperatures. The latter part is known as the thermal desorption step. It examines low molecular weight components, residual solvents, and additives.
• Evolved Gas Analysis: The same sample is put into the Pyrolysis unit which is set at a low temperature. The temperature is then increased, and the component is evolved. This testing helps to determine the temperature range of the desired component.
• Low-Temperature Thermal Desorption: It takes place for products such as residual solvents, additives, and other off-gassed components. Here, in this case, polymer identification is not required.
• Reactive Pyrolysis: Data interpretation of complex mixtures is difficult. For example, for certain classes of compounds, such as polyesters. A chemical reaction occurs when the derivatization technique is utilized. A pyrolysis chamber is a chemical reaction that allows easy interpretation of the products.
• Quantitative Pyrolysis-GC-MS: When the amount is not calculated using another technique, then this testing approach is used. An example component such as Irganox, Irgafos have low ppm additive.
• Cyrotrapping Pyrolysis-GC-MS: This testing technique is used to narrow down the chromatographic band and then improve the detection limit of the sample, which is cryptrapped with the help of liquid nitrogen.

• Capable of examining compounds and materials which are not appropriate for other traditional GC-MS
• The analysis is done with micrograms of samples
• Reduction of sample preparation
• Ability to reach multiple block polymers due to effective study of polymeric structures

Our data scientists can interpret the data effectively and provide useful results and insights based on the analysis. There is a list of technical specifications which are needed. Ramp rates should be in the range of 1 degree Celsius to 100 degree Celsius per minute. The technique requires Nitrogen purged environment, and Nishka Research scientific group takes care of all of the requirements. The temperature range should be between 30 degrees Celsius to 800 degrees Celsius. We follow all the specifications and the detection limit is calculated and analyzed. We make sure that the components are seen in the range of ppm.
