Application Notes: GC-MS
Smart-Ramped Pyrolysis-GC–MS of Acrylates and Methacrylates
Smart-ramped pyrolysis-GC–MS analysis of (meth)acrylates in consumer products, caulk, and nail hardener gives maximum info in a single run without method development.
Sampling Plant Volatiles for GC-MS Analysis
Solvent-free extraction by passive sampling using TF-SPME and HSSE, and by active pumped sampling onto sorbent tubes, are compared for TD-GC–MS analysis of volatiles.
Sensory Directed Flavour Analysis of Pea-Based Tuna
Olfactory detection of sensory-active compounds guides GC–MS analysis for efficient flavour assessment of foodstuffs and their plant-based replacement products.
Flavour Analysis of Hard Seltzer Beverages
Solvent-free extraction and analyte concentration using TF-SPME and SBSE are optimized for TD-GC–MS determination of flavour compounds in hard seltzer beverages.
Using Pyrolysis-MS for Evolved Gas Analysis
This study demonstrates the use of pyrolysis-(GC¬–)MS to generate simulated TGA-MS data for polymers. The mode of operation is also referred to as evolved gas analysis.
Microplastics in Water by Smart-Ramped Pyrolysis-GC-MS
Smart-ramped pyrolysis-GC¬–MS analysis of microplastics in water filtration residue gives maximum info in one run. Examples are runoff, grey-, pond-, and bottled water.
Automated Determination of VOC Emissions
A micro-scale chamber method performs DNPH derivatization and Tenax TA sorption for analysis of formaldehyde and carbonyl compounds by LC–UV, and VOCs by GC–MS.
EPA 8260D with the CDS 8500
Analysis of volatile organics in soils using the CDS 8500 Automated Purge and Trap System.
Optimized Hydrogen Fuel Impurity Analysis
This application note shows the robust, reproducible analysis of trace VOCs in hydrogen fuel by TD–GC–MS/SCD.
