Erbium has a strong absorption in uv and visible range, It is used in HPlc calibration for the wavelength accuracy verification of the PDA detector.
B and C only
by injecting the sample in to a HPLC system having PDA detector or Scan the Quetiapine Fumarate sample solution in UV range.
PDA - Photo diode array UV- Ultra violet with use of PDA detector, we can measure the area or height of particular peak at different wavelengths ranging from 200 to 800 nm by injecting the solution at once. Where as in uv detector we can measure the area or height of the peak only at two different wavelengths. But that wavelengths also to be selected before injecting the solution.
A calculator. Or just a PDA(what does pda mean). or even just a book. we need more info
PDA's are really becoming obsolete as smartphones are now taking over. Most smartphones are better than PDA's because most smartphones are able to have useful and fun apps downloaded on them and usually have more features in general than PDA's today.
what is a pda in an aircraft
If you asked what a file on a PDA is, my answer is everything. anything you see on a desktop computer can also be a file on a PDA. If you asked what a .pda file (having an extension of PDA), sorry, no idea. :)
PDA's can be connected to a computer. Files can be transferred from the PDA to the computer and from the computer to the PDA. Data such as phone numbers, addresses and appointments can be synchronized between PDA's and computers so the information can be the updated.
A palmtop is a pda which is a personal digital assistant and a pda is a palmtop
iTouch will have a better battery span than a PDA will however there are far less applications on an iTouch than you can get with a PDA. A PDA is still more appropriate if you need it for computer functions� iTouch has more entertainment value. Touch does not support WMA files which is a music store standard. You can only play what you buy from iTunes. PDA's have the ability to play pretty much any music. The storage capacity of an iTouch smashes that of any PDA although PDAs are capatible with SD and CF memory cards so extra memory is always an option.
