Clarity INT9 用户手册

Clarity - INT9 A/D converter 

 

Using the INT9 card 

Select Detector 
Selects the detector whose parameters will be 

set. If there is only one detector (channel) 

configured on the Clarity Instrument, this 

control will not be displayed. 
Range 
Selects the input voltage range (in mV). The 

selected range corresponds to the maximum 

output voltage of the detector that the A/D 

converter can still process.  
Available ranges for INT9 card are 

, 

 

and 

.  

Sample Rate 
Depending on 

 filter selected 

in the 

 

dialog, the available sampling rates are 

, 

, 

, 

, 

, 

 and 

 samples per 

second (for 50Hz mains frequency filter) or 

, 

, 

, 

, 

, 

 and 

 samples per 

second (for 60Hz mains frequency filter).  
Higher sampling rate allows for the 

measurement of narrower peaks, but it also 

means a larger amount of data which will affect 

the size of the resulting chromatogram and the 

speed of its processing. 
Sample rate sufficient for successful peak 

detection is about 20 samples per narrowest 

peak. 
A higher sampling rate also increases the 

amount of noise.
