CO, C2H4 and C2H6 quantification was performed using a flame ionization detector (see example traces in Supplementary Fig. 42). A thermal conductivity detector was used for H2, N2 and O2 detection. However, the small amounts of O2 produced by tandem devices under unassisted operation (~1.1...
d Long-term stability test of Vac at total current of 7 A and (e) corresponding time-dependent HCOOH production rate. Error bars represent the standard deviation of three independent measurements. The cell voltages were compensated by iRΩ correction with an RΩ value of ~6.3 ± 0.1 ...
PCPC's excellent flame-retardant performance has been proven by both the vertical combustion test (UL94 V-0) and the limiting oxygen index (LOI) value (29.1%). The underlaid flame-retardant mechanism of PCPC was clearly elucidated. As a result, we confirmed that the generated cyclic ...
The GC device was equipped with two thermal conductivity detectors for H2, O2, N2, He, CO and CO2 signals and a flame ionization detector for CH4, C2H4 and C2H6 signals. The GC was carried out using packed columns of two Porapak-N, a Molecular sieve-13X, a Molecular sieve-5A, a ...
The only instruments in the market most optimally fulfilling these requirements are the Steinfurth CO2 testers. Where for other technology providers fulfilling of all these essential requirements in one instrument solution is not possible, the Steinfurth CO2 tester additionally to its unique combination of...
Abstract: Using a chromatograph two hydrogen flame test device, a methane reformer, a single injection for simultaneous determination of polymer-grade propylene in the hydrocarbon impurities and trace CO, CO2. Keywords:GC;Propylene;Hydrocarbon impurities;CO;CO2 丙烯经聚合形成聚丙烯。聚丙烯材料是国民经济...
These self contained pneumatic systems require no external energy or power supply. Upon flame impingement or heat, the pressurized detection tubing will burst and activate the cylinder valve to open and release the extinguishing agent. PRI-SAFETY electric equipment fire suppression systems a...
