Quantitative Analysis of Polycyclic Aromatic Hydrocarbons at

2018/09/12 · Headspace solid-phase microextraction (HS-SPME) was used in combination with gas chromatography-mass spectrometry (GC–MS) for the analysis of polycyclic aromatic hydrocarbons (PAH) at part per billion levels in fish oil

Rapid on-site identification of hazardous organic compounds at

2019/11/15 · For each burn, four 22 mL glass screw cap headspace vials with PTFE lined septa (Restek, Bellefonte, PA, USA) were prepared as indicated in Table 1. One vial was prepared for headspace sampling (HS), by adding 2 g of sodium chloride salt (ACS Reagent; Sigma Aldrich, Darmstadt, Germany).

Hydrogen Sulfide Measurement by Headspace-gas

2014/10/21 · Then, the headspace vials were hermetically sealed with 20 mm (i.d.) magnetic PTFE/silicone septum caps, vigorously shaken and vortexed to allow for direct contact between the acid and Na 2 S. The yield from H 2 S generation was previously verified by comparison with H 2 S dilutions obtained from pure commercial H 2 S, and H 2 S generation above these conditions was quantitative.
