Modification of the Fluorescence Attachment for the Beckman Model Du Spectrophotometer.
‘l.THEFOLLOWING describes a relatively simple amid inexpensive modification of the Beckman No. 2980 fluorescence attachment for the Beckman DIT spectrophotometer which permits rapid and easy imiterchange of both primary and secondary filters and increases the flexibility and adaptability of this instrument in fluorimetric analysis. The filter plate assembly for the secondary filters as original...
متن کاملthe search for the self in becketts theatre: waiting for godot and endgame
this thesis is based upon the works of samuel beckett. one of the greatest writers of contemporary literature. here, i have tried to focus on one of the main themes in becketts works: the search for the real "me" or the real self, which is not only a problem to be solved for beckett man but also for each of us. i have tried to show becketts techniques in approaching this unattainable goal, base...
15 صفحه اولAdaptation of the Beckman Model B spectrophotometer to the measurement of dilute fluorescent solutions.
HE INCREASING USE of fluorimetry in routine analysis is reflected in a variety of commercially available instruments which, in many instances, are either prohibitive to the average laboratory due to high cost or lack proper sensitivity. Unlike the Beckman DU spectrophotometer, its clinical counterpart, known as Model B, is not provided with a standard fluorimetric attachment. The versatility of...
متن کاملThe adaptation of the Beckman spectrophotometer to measurements on minute quantities of biological materials.
The smallest volume that has been used with commercial photocolorimeters is about 1 ml. The sensitivity and optical system of the Beckman spectrophotometer (model D or DU) are such that it can be readily adapted to volumes of the order of 50 c.mm. (0.05 ml.) without sacrificing length of the light path through the colored solution. With volumes of this order of magnitude the size of sample requ...
متن کاملMeasurement of spectral bandwidth, as exemplified with the Beckman "Enzyme Analyzer System TR spectrophotometer".
This paper describes simple methods for determining spectral bandwidth by measurement and by calculation. We measured the spectral bandwidth of the monochromator from the Beckman Enzyme Analyzer TR, and found it to be 3.5-4.0 nm (av 3.8) by two different methods. We visually estimated it to be 4 nm. Using the specifications for the diffraction grafting, focal length, and fixed slit width, we ca...
