Capillary columns are easily overloaded by injecting High Amount of Sample Concentration.
To Reduce or overcome this problem Split Ratio is Incorporated The Main use of this Split Ratio is Inject Less amount of Sample of interest into column or passes through it.
The Q? comes in a mind How it could be Done
Split vent is option Provide by Every manufacture like Agilent and shimadzu how it works i will expalin
Example :- ur method shows a split ratio of
1:30 Metan that 150ml/min of Split vent flow and Colum flow 5ml/min If u have Installed 0.53mm id Colum of any pahse.
Similarlly 1:50 mean 250ml/min of split ventflow and 5ml/min of column flow
formula split ratio = split vent flow / column flow
if know any of the parameter u can calculate by substituting in the above formula ...
thanks
