A mass flow controller includes a base having a passage that allows a fluid to pass through the passage. A first control valve controls a mass flow of a fluid passing through the pa
S1. By using a mass flow controller, five common gases including helium, nitrogen, air, argon, and carbon dioxide were flowed into the sealed cantilever-mounted chamber through a hole beneath the cantilever (Fig. S2). The gas exhausted was collected to confirm an exact flow rate with a ...
Each intelligent controller of SCSI manages the flow of information, and the devices it supports may be made up of several disks or different implementations of RAID that are directly attached to their particular dedicated host servers. The drive arrays, when equipped with RAID 5 disks, strip ...
The inlet section consisted of a centrifugal pump delivering continuous flow of liquid to the reactor, the liquid flow is mixed with a steady flow of H2 which is sent through a highly precise thermal mass flow controller. An injector port is inserted at about 3 cm from the inlet of the ...
The precipitated water 74 is circulated via a flow controller (e.g., a pump) from the condenser 70, through the preheating heat exchanger 54 (where heat from the precipitated water 74 is transferred to the aqueous feed 50). Respective portions of the precipitated water 74 are then (a) ...
A man-portable membrane inlet mass spectrometer has been built and tested to detect and monitor characteristic odors emitted from the human body and also f
(99.999% purity) carrier gas was used with a flow rate of 1 ml/min. The injection volume was 1 µl (splitless). The temperatures of the MSD transfer line, ion source and quadrupole were 280, 230 and 150 °C, respectively. The analysis used electron ionization with 70 eV in...
rifted margins; fluid flow; detachment faults; mass balance; serpentinization; Alps; Pyrenees; Iberia margin; mantle-reacted fluids1. Introduction Fluid-flow and mass transfer not only play an important role in continental metamorphic core complexes [1,2] and oceanic core complexes [3], but also...
However, the forces acting on the cantilever by the surrounding fluid dramatically increase the amount of dissipation, as explained in Section 2.3, and therefore the Q factor of the resonant response is low (around 10 or below). As shown in Figure 3, in this condition the peak in the ...
Purge—The Max-Trak Mass Flow Controller is supplied with the ability to open the valve far beyond the full scale position to allow them to be cleaned. This is usually accomplished by blowing clean, dry nitrogen through the instrument. When the valve is opened to this cleaning position, it ...
