Gas Chromatography Mass Spectrometry (GC-MS) Information

What is GC-MS? GC/MS combines two analytical tools to identify and measure the concentration of chemicals found in foods, consumer products, pharmaceuticals, fuels, the environment, and more.

Read on to learn more about the typical components of a GC/MS instrument and its basic principle of operation.

Applications

A Complete Workflow Solution for Extractables and Leachables of Polymer Materials

Identification and quantification of extractables and leachables in packaging material is critical for consumer safety. Potentially requiring the analysis of hundreds of unknowns, these complex compounds can be difficult to identify. Utilizing a high-resolution accurate mass GC/Q-TOF with low energy EI and chemical ionization for molecular mass generation and structure elucidation provides confident identification and quantitation based on high-resolution data.

Determination of Flavor and Fragrance in Food and Beverages Utilizing HRAM GC/Q-TOF

Flavor and fragrance in food and beverages are intricate characteristics of the product and determine consumer perception of quality. Analysis of the complex chemical substances that provide unique taste and smell can be challenging. A high-resolution accurate mass GC/Q-TOF instrument can be used to determine these complex compounds in specific proportion or amount, influencing taste and smell. The high-resolution spectrum combined with low energy EI and CI capability allows confident compound identification and quantitation.
