Despite having been developed primarily as a tool for
process control, SIA also has found a place in the analytical
laboratory, because of its inherent advantages such as
robustness, reliability, and low consumption of sample and
reagents. It is also based on the use of a syringe pump,
which is highly dependable, requiring less maintenance than
peristaltic pumps and having excellent repeatability when
used to measure small volumes. It has been used successfully
in the determination of nitrate and nitrite in matrixes such
as water samples
