The Agilent 7890 gas chromatograph mass spectrometer (GCMS) is an analytical instrument used in chemistry for the separation, identification, and quantification of volatile and semi-volatile compounds. It uses gas chromatography to separate compounds based on their chemical properties and mass spectrometry to identify and quantify the separated compounds.

The Agilent 7890 GCMS is commonly used in various fields, including pharmaceuticals, natural products, food and beverage, environmental analysis, and forensic science. It can analyze a broad range of compounds, including drugs, metabolites, volatile organic compounds, and environmental pollutants.

The Agilent 7890 GCMS can be used with a variety of separation techniques, including headspace, solid phase microextraction, and thermal desorption. When paired with a Netzsch differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA), the Agilent 7890 GCMS can analyze complex mixtures in polymer and material science applications.

The Netsch STA DSC-TGA is used to characterize the thermal properties of materials, such as the melting point, glass transition temperature, and thermal stability. The GCMS then separates and identifies the volatile and semi-volatile compounds released during the thermal analysis. The Agilent 7890 GCMS with a DSC-TGA is a powerful analytical tool in material science, enabling researchers to obtain high-quality data with high sensitivity and selectivity.
