that could be inverted or transited – these machines were called transits. Time went on and in the end most instruments – both theodolites and transits were manufactured with telescopes witch could be inverted. Now, the original distinction is no longer suitable and the way instruments were called was a matter of local usage. The vernier-read instruments were called transits and more precise ones with optically read instruments were called theodolites. Earlier theodolites used to have verniers and micrometer microscopes for reading angles, then they were manufactured with optical systems with witch the user could read both horizontal and vertical angles through an eyepiece located near the telescope. The newest theodolites showed the horizontal and vertical angles digitally in a display window

Capillary electrophoresis i.k.

  7:  A  schematic  representation  of  zone  electrophoresis,  isoelectric  focusing  and  isotachophoresis    Capillary zone electrophoresis (CZE) Because  of  their  ease  of  use  and  versatile  applications  CZE  is  the  most  commonly  used  method  which is primarily used for the separation of small water­soluble molecules. It is  used  in  the  analysis  of  amino  acids,  peptides,  and  ions  of  various  enantiomers  (optically  active  compounds)  and  many  other  ionic  compounds.  CZE  ­  it is the simplest form of HECE  (High  Efficiency  Capillary  Electrophoresis)  as  capillary filled only with buffer. Separation of  materials into discrete zones is due to migration at different speeds.  The  electroosmotic  flow  (EOF)  makes  possible  the  separation  of  both  cations  and  anions

computer), you might consider using Ethernet between the two systems. Although you may not need the speed of Ethernet, the transformer-coupled cabling eliminates common grounds and all AC ground-induced failures. Another option is to use a fiber-optic interface, which has no electrical con- nection. If one end of the system is too simple to make a high-speed inter- face feasible (such as a design that uses a microcontroller), you could use an optically isolated serial interface. You can either buy off-the-shelf RS-232 isolators, or define your own optical isolation scheme. Finally, in some cases, you might be able to specify that one of your system components have its own safety ground. In large systems that typically require an electrician to come out and wire power, this may be feasible. In the 208V/110V example, you would specify that the 208V equipment have its own safety ground (not shared with anything else in the building)
