Oct 04, 2013 · The headspace operating conditions were as follows: gentle shaking for the sample equilibration at the temperature of interest; vial pressurization time = 0.2 min; and sample loop fill time = 0.2 min. The volume of the headspace sample vials was 21.6 mL. 3. Results and discussion3.1. Principle of the method

Feb 07, 2014 · The headspace operating conditions were as follows: strong shaking for sample equilibration at the temperature of interest; vial pressurization time = 0.2 min; and sample loop fill time = 0.2 min. The volume of the headspace sample vials was 21.6 mL. The volume of the sample loop was 3 mL. 3. Results and discussion3.1.

Mar 11, 2019 · The production of 1-undecene was directly measured from the headspace of the cultivation vials using solid phase micro-extraction (SPME)–gas chromatography mass spectrometry (GCMS), as described by Rui et al. . The production of 1-undecene by different strains is shown in Fig. 3.

Before each extraction, the samples were diluted in water in a ratio of 1:4 owinge to modification of ion power and then properly mixed. Subsequently, 10 mL was transferred into 20 mL headspace vials and sodium chloride was added to a final concentration 28.5% (w/v). The vials were then closed by a cap with a Teflon septum.

where A m represents the production of N 2 of mass m through anaerobic ammonium oxidation, A total = A 28 + A 29, and F N is the fraction of 15 N in NO 3 − (typically, ∼0.95). Denitrification was assumed to produce 28 N 2 , 29 N 2 , and 30 N 2 through random isotope pairing ( 29 ) as follows:

A very small amount (approximately 10-30 mg) of latex was added to a sealed headspace sample vial (20 ml). A near-complete monomer mass transfer from both liquid (aqueous phase) and solid phase

Sep 21, 2019 · Aliquots (6 mL) were placed in 20-mL SPME headspace vials, to which 25 g/L of α-CD, β-CD, or γ-CD were added. Samples were then heated to 35 °C in an incubator (Ratek, Boronia, VIC, Australia) with agitation (200 rpm) for 20 min, after which samples were cooled to ambient temperature and analyzed by GC-MS. Samples were prepared in triplicate.

Jan 17, 2022 · Back in the lab, vial headspace was analyzed for N 2 O isotopic composition using the same IRMS as described above. 20 mL water in 110 mL serum crimp vials allowed direct headspace measurements

Groundwater samples for DIC measurement were filtered with a 0.2 micron filter, collected in 40-ml amber vials without headspace, and refrigerated until analysis. 3.2 Groundwater Analysis Dissolved gas concentrations and carbon isotope values are measured for each sample using a headspace equilibration technique (Kampbell & Vandegrift, 1998 ).

Headspace Solid-Phase Microextraction (SPME) Gas Chromatography Mass Spectrometry (GCMS) was used to identify a range of volatile compounds such as alcohols, esters and hop-derived aroma compounds.

Dec 15, 2020 · Vials were weighed to determine the mass of each sample, and basified to arrest further microbial activity (3 ml 1M potassium hydroxide). CH 4 concentrations were determined via a headspace equilibration method, and 6 ml of headspace gas were injected into a gas chromatograph (SRI 8620 Multi Gas, thermal conductivity and flame ionization

Dissolved H(2) and CO(2) were measured by an improved manual headspace-gas chromatographic method during fermentative H(2) production with N(2) sparging.
