4.2.2.  Low flow cell - ASM1222  

The low flow cell that can be secured to the end of the probe for continuous analysis of your 
process. The flow cell is 

equipped with two 1/16” NPT fittings to attach pipelines too, or it can 

be  assembled 

with  two ¼”  Swagelok nuts  attached to a  short  section  of  pipe  on  opposing 

sides. It is designed to force liquid past the ATR and is primarily used for lab work where flow 
rate and volume are low. 

It is fixed in place using a tri clamp that locates over the rear of the flow cell and two semi-
circular  collars 

‘C-pieces’  that  fit  around  the  probe.  Ensure  that  the  C-pieces  make  good 

contact with the probe and that the pins are seated inside their corresponding holes. Slide the
