A DAD (diode array detector) uses an array of diodes to measure absorbance at multiple wavelengths simultaneously, providing spectral information. A PDA (photodiode array detector) is a type of DAD that specifically uses photodiodes for detection. Both detectors are commonly used in chromatography to detect and quantify analytes in a sample.

What is different between pda detecto and uv detector?
technical difference is flow cell is placed in between lamp and optics but in uv it is placed after grating. and flow cell receives monochromatic light in uv detector but polychromatic in pda.
What difference between pda and uv detector in hplc?
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.
What is xda what is the difference between pda and xda?
An XDA is a PDA with a phone.
What is the common difference between PDA and palmtop?
A palmtop is a pda which is a personal digital assistant and a pda is a palmtop
What is the difference between a PDA and iPod Touch?
PDA is where you are physically touching someone and an ipod touch is a device where you can listen to music
Is there a difference between a smartphone and a PDA?
Yes, Smarephones offer about every feature of a PDA and then some, it is like a computer and a phone all in one, as a PDA does not perform phone functions.
What is the difference between laptop computer and a PDA?
You can access the internet on a laptop but not on a PDA.
What is the difference between GSM and PDA phones?
GSM is a network - more exactly, it's a - <quote: Babbel> digital cellular communication system used in many countries (based on a variation of TDMA technology) </quote> A PDA phone is a phone which is also a PDA, or a PDA with a phone function. it's on the hardware aspect. So, I guess they're irrelevant.
Can PDA's connect to PC's?
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.
What is difference between a PDA and microcontroller?
a microcontroller is just 1 integrated circuita PDA is several integrated circuits, one or more circuit boards, a handheld size housing, a rechargeable battery, a touchscreen I/O device, etc. that is ready for a user to operate
How much memory does a PDA typically hold?
The PDA can typically hold between 16 MB to 64 MB of memory.
Why is Erbium perchlorate is used in calibration of HPLC?
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.
