The peristaltic pump tubing has to be washed prior to use.
The common way is to run about 5% HNO 3 (v/v) solution.
If customers use HCl, Sn is eluted from the Tygon tube.
In this case, 3% HCl (v/v) should be pumped at 0.1 rps
for less than an hour by the new peristaltic pump tube.
Caution: Some chemicals attack the peristaltic pump tube. This might cause leakage in the sample
introduction and drain lines and corrosion of the sample
introduction system.
