Compact detection cell

Luminol Microperoxidase-catalyzed ILITC- H202 Phosphate buffer (pH 10.8) Compact detection cell using optical fiber 14 amol (for luminol) 110... 

Gas-diffusion separators have been integrated with detection cells to produce more compact systems both in optical sensing and atomic absorption spectrometry. These will be described in more detail in the sections on the coupling to individual detectors (cf. Sec. 5.4.2, 5.5.2)... 

CoAd Blood Testing oa Sickle Cell Anemia and Related Vl6-oAdeAS by AlienachAomatogAaphlc Methods. The CM-Sephadex procedure easily detects Hb-S and Hb-C at birth but the diffuse zone of Hb-A has on occasion been difficult to see. Substitution of CM-Cellulose for CM-Sephadex has yielded a superior mlcrochromatographlc method, and the compact, well-defined zones of the CM-Cellulose column facilitate the Interpretation of the results even though the amount of sample Is only 20% as great. The CM-Cellulose method Is as simple and rapid as the original CM-Sephadex procedure (27. 28). 

This pathway provides several amplification steps between odorant binding and signal generation. Due to the electrically compact structure of the cell, it is possible for the activation of only a few tens of channels to drive the membrane to the threshold for action-potential generation. Thus, it is theoretically possible that the limit of olfactory detection is a single molecule, although this has not yet been conclusively demonstrated. 

The solid reference electrode technique is able to obtain almost the same results as the SO2 gas concentration cell method. The apparatus can be made more compact, simple and cheaper by using the solid reference electrode technique. The SO2 gas detection with solid reference electrode method is a promising technique for practical applications.
