IC
|
0.002-0.32
(Dependent on size of the sample loop and column type; detection limit
may be impacted by the presence of carbonate eluting close to
phosphite)
|
Relatively cost-effective; separation from most interferences
|
Low detection limit requires large sample volume, possibly causing
saturation by other ions; possibly interferences by ions with similar
retention times; can analyse multiple P species but not all
|
This study; [6]
|
IC + ICP-MS
|
0.002-0.003
(Dependent on the size of the sample loop)
|
Low detection limits achievable with small sample sizes; separation of
interferents with similar retention times in the IC
|
High installation costs; can analyse multiple P species but not
all
|
This study; [4, 6]
|
UV-VIS spectrophotometry |
0.36 |
Most cost effective; separation from
many interferences; fast |
High detection limit; some interferences may
persist; can analyse multiple P species but not all |
[16] |
NMR
|
6.46
(Dependent on length of run or number of scans, strength of the magnet,
type of probe)
|
Can analyse greatest variety of P species; separation from
interferences
|
High installation costs; slow analysis; high detection limit
