Research and Analysis

Laboratory Information

PEA offers comprehensive plant volatile profiling in a state-of-the-art trace gas analysis laboratory with gas chromatography (GC) and detection by Time-of-Flight Mass spectrometry (TOFMS) with standard (70ev) and soft (16ev) ionization, quadrupole mass spectrometry (QMS), chemical ionization mass spectrometry (CIMS), Vacuum ultraviolet (VUV), flame ionization detection (FID), and photoionization detection (PID).


Our suite of multimodal analytical capabilities enables highly sensitive detection of more than 200 plant volatiles including terpenoids and organic sulfur, oxygen, and nitrogen compounds. Following EPA protocols, identification and quantification are based on comparison with NIST authentic standards for more than 100 compounds and can be extended to additional compounds on request.
