Filling the sample inlet tubings
We recommend using a purge tubing for filling the sample inlet tubings
and the sample pump. When the tubings are empty or the pump is dry,
the purge tubing must be used.
The procedure for using the purge tubing is described in section
5.2.2 Removing air using a purge tubing.
3.7
Using samples with high viscosity
When using samples with high viscosity (4–5 cP) at flow rates above
25 ml/min, it is necessary to use teflon tubings with i.d. 1.6 mm and
o.d. 1/8" as inlet tubings to Air-912N and Pump P-960.
When using samples with very high viscosity (up to 10 cP) the
maximum flow rate is 10 ml/min. We also recommend using teflon
tubings with i.d. 1.6 mm and o.d. 1/8" as inlet tubings to Air-912N and
Pump P-960.
