Explain how tcd is measured in the bioreactor
WebThermal conductivity detectors in PGC are universal detectors in that they can be used to measure any component (Figure 2). Typically, TCDs are used to measure percent level components, but because it is a concentration-sensitive detector, the TCD can be designed for lower level analyses by optimizing the detector volume and sensing elements. WebA universal detector and can detect air, hydrogen, carbon monoxide, nitrogen, sulfur oxide, inorganic gases and many other compounds. Thermal conductivity (TCD) is a commonly used detector in gas chromatography. TCD works by having two parallel tubes both …
