Total carbon and total bound nitrogen analyses are available within the MAC lab. The available instrumentation can also differentiate organic carbon, inorganic carbon, and purgeable organic carbon. Filtration at 0.2 micron prior to analysis results in dissolved values. Measurement of the total bound nitrogen yields the sum of nitrate, nitrite, organic nitrogen, and ammonia.

The costs shown above is an estimate, and will be discussed and agreed upon prior to sample analysis.
*A flat rate will be charged for this and is independent of the number of ions requested.
Setup cost reflects the cost of calibration, duplicates, augmented samples, and QC checks.
When sample results exceed the instrument calibration range, a dilution and reanalysis will be required.
