To convert 120 mL H2S into mg at NTP (0 deg C, 1 atm abs.): 120 mL/m3 x 1.5392 mg/mL = 184.7 mg/m3 at NTP. However, the same 1 m 3[/sub] of gas at NTP would expand under "actual" conditions (50 deg C, 110 kPa) to: 1 x [(273+50)/273] x 101.3/110 = 1.09 m3...
BPA was extracted and analysis of concentration was performed using gas chromatograph/flame ionization detector. In some receipts, BPA was not detected but in others it was as high as 19 mg for a 12-inch long receipt, which is in line with concentrations indicated in patents. This study is ...

The results indicated that the highest yield of the liquid fraction was obtained at 500 ºC (42.11%), while 400 and 600 ºC resulted in higher production of biochar and pyrolytic gas. The bio-oils obtained from the pyrolysis process had an average calorific value of 68% compared to ...
Moreover – on the basis of high lateral resolution SPEM, X-ray photoelectron spectroscopy (XPS) and EDX analyses, – we found that, after operation, Pt is transported onto the fibres of the gas-diffusion layer (GDL). Space-resolved XPS shows a peak shift of the Pt 4f7/2 level to ...
The column used was HP-5 MS; 30 m × 0.25 mm × 0.25 µm (J & W, Agilent Technologies, Palo Alto, CA, USA) with helium as a carrier gas at a total flow of 1 mL/min. Chromatographic conditions were as follows: split injection at a ratio of 100:1, the injector was set at ...
3— Example of host status window. by using the concept of an expanded system. The canonical equations shown below indicate the equations of motion for particles and an MD cell and heat bath when NTP ensemble simulta- neously controls the temperature and pressure. d dt m α dsα dt = ...
This study investigated the aroma compounds of 20 differential peach cultivars using headspace solid-phase microextraction-gas chromatography–mass spectrometry (HS-SPME-GC–MS). A total of 82 distinct aromas were identified, comprising 6 lactones, 16 esters, 24 alcohols, 5 aldehydes, 12 ketones, ...
A novel photoflow setup designed for a gas–liquid biphasic reaction turned out to be useful for the direct use of chlorine gas. The setup employed sloped channels so as to make the liquid phase thinner, ensuring a high surface-to-volume ratio. When ethylene carbonate was introduced to the ...
