1) High sensitivity : detection limits of 0.1-0.5ng(or 0.2-1ppb levels for drinking water) can be routinely achieved.
2) Selectivity : only N-methylcarbamates and N-methyl carbamoyloximes plus components reactive to OPA under the specified conditions are detected.
3) Minimum sample preparation : drinking water can be directly injected into the system.
4) The analysis is easily automated with the addition of an autosampler.
