TG-MS: Thermogravimetric - Mass Spectrometry

Detect very low levels of impurities in real time with our fully integrated Thermogravimetric - Mass Spectrometry systems. Samples heated on the TGA release volatile materials and/or generate combustion components that are seamlessly transferred to the MS for identification, making these hyphenated solutions powerful tools for quality control, safety, and product development.

TG-GC/MS: Thermogravimetric - Gas Chromatography/Mass Spectrometry

Although TG-MS allows real-time monitoring, it can be confusing due to overlapping events and higher mass ions obscuring those of lower mass. By adding gas chromatography (GC) to the system, these events can be cleanly separated and very low levels of impurities detected.

Heating a sample on the TGA causes a sample to release volatile materials or generate combustion components as it burns. These gases are then transferred to the GC, where the components can be collected on a trapping media, in a gas sampling loop, or deposited on the head of a column. The sample can then be run by GC to separate the material, and the peaks identified by the MS. Because of its ability to detect very low levels of material in complex mixtures, the TG-GC/MS is a powerful tool for quality control, safety, and product development.

TG-IR: Thermogravimetric - Infrared

The combination of a Thermogravimetric Analyzer (TGA) with an Infrared Spectrometer (TG-IR) is the most common type of Evolved Gas Analysis (EGA) in use today. By heating a sample on the TGA, a sample will release volatile materials or generate combustion components as it burns. These gases are then transferred to the IR cell, where the components can be identified. Because of its ability to detect functional groups, IR analysis allows greater understanding of the processes seen in the TGA. The PerkinElmer TL8000 transfer line is a state-of-the-art system for TG-IR. Unlike simpler systems that simply move the gas to the TGA, the TL8000 is designed to make sure every component evolved in the TGA is transported to the IR.

TG-IR-GC/MS: Thermogravimetric - Infrared - Gas Chromatography/Mass Spectrometry

Hyphenating TG-IR-GC/MS is a powerful approach for analysis of an unknown mixture to determine its primary components and identify additives or contaminants. This information may be needed, for example, to evaluate a competitor’s product or to determine compliance with regulations. The PerkinElmer TL9000 transfer line is used to allow TG-IR-GC/MS analysis on a sample by moving the off gases to the FT-IR and GC/MS after their evolution in the TGA. It acts as the interface between a TGA or STA, an FT-IR like the Frontier or Spectrum Two FT-IR, and a Mass Spectrometer or GC/MS, such as the Clarus SQ 8.

UV-DSC: Ultraviolet - Differential Scanning Calorimetry

Gain powerful new insights into the effects of UV radiation on various materials. Our hyphenated UV-DSC solutions help scientists find ways to reduce the release of VOCs from coatings, more quickly bind electronics in manufacturing, cure dental resins and lens coatings, and produce pharmaceuticals and chemicals that resist degrading when exposed to UV light. Whether you seek a state-of-the-art DSC with true isothermal control for research and development, or a less expensive alternative designed for quality control and manufacturing, we have the right UV-DSC solution for your lab.
