I got a basic question.
Whats the difference between a VWD Detector and a DAD Detector.
We are using a 1260 machines on the VWD
And a 1290 on the DAD
The only visible difference on the detectors is the range from input and output
aprox 5cm on VWD and 3 cm on the DAD. ( I didnt measure that value exactly )
And the pressure 40 on the VWD and 60 on the DAD.
it looks very similar.
is the difference that on a DAD the signal from the lamp goes first thru a prisma and then thru the sample.
On the VWD first passes the sample and then the prisma.
I know the main benefit is on the DAD that you can record a full spectrum of a single peak.
For identification purpose.
Thanks in advance
