2 ml vial caps with writing space for GC Sigma

N-Heterocyclic Carbene Nitric Oxide Radicals

In a GC vial, 20 mg of 2a was placed and sealed with a GC vial cap. The vial was kept in a sand bath on a hot plate at 120 ºC for 30 min. The red brown solid became yellow. 30 L of the head space was injected in a splitless mode and analyzed by GC-MS. The total ion chromatogram and mass spectrum in Figure S3 corresponds to nitrous oxide (N2O).

Hydrogen Sulfide Measurement by Headspace-gas

Abstract. The aim of our study was to present a new headspace-gas chromatography-mass spectrometry (HS-GC-MS) method applicable to the routine determination of hydrogen sulfide (H 2 S) concentrations in biological and gaseous samples. The primary analytical drawback of the GC/MS methods for H 2 S measurement discussed in the literature was the absence of a specific H 2 S …
