MCFA detector

Adsorption of CO and mixtures of CO, O2, and CO2 was performed in a diffuse reflectance Fourier transform infrared spectrometer (Thermo Nicolet) equipped with an MCFA detector, a diffuse reflectance accessory, and a high-temperature reaction chamber (Praying Mantis, Harrick). The catalyst samples were purged with helium at 250 °C for 30 min, reduced by 10% H2/He at 10 °C/ min, cooled under He flow at room temperature, and then exposed to a 5% CO/... 

FIGURE 1.4 Manifold of a multicommutated flow injection system (MCFA) developed for simultaneous determination of acid phosphatase and alkaline phosphatase activity consisting of substrate/buffer delivery module (a), sample delivery cell module (b), reaction module (c), and detection module (d). V—valves, P—pumps, HC—holding coils, PEDD—paired emitter detector diode, NPP— p-nitrophenyl phosphate, DEA— diethanolamine. (Adapted from Tymecki, L., K. Strzelak, and R. Koncki. 2013. Anal. Chim.

There is a vast array of devices that can be employed in SIA fluidic manifolds such as reaction coils, phase separators, solid reactors, bead reactors, gas diffusion/permeation units, stirred mixers, solvent extraction units, renewable columns or additional pumps, valves and detectors (Marshall et ah, 2003 Economou, 2005 McKelvie, 2008 Ruzicka, 2014). More complex units that can be hyphenated to basic SIA manifolds include complete FIA, MSFIA, MCFA, and multipumping systems (Pinto et ah, 2011) and separation instrumentation (Section 2.11).
