How do I purge the FLASH-ELSD (external ELSD)?
Use a measuring cylinder to determine the flow entering the ELSD.
Set the split valve such as to obtain a flow rate of approximately 1 ml/min. in the ELSD, for a pump flow rate of 50 ml/min. (open the split valve by rotating counter-clockwise).
Reconnect the FLASH-ELSD inlet tubing, then purge the puriFlash® and Flash-ELSD with isopropanol using the predefined "ELSD Nebulizer cleaning" method (the method takes 4 minutes).
You can stop the purge once the ELSD signal is stable.
