SCA-130-103

■ TOC-L ■ Example: River water
To prepare the sample accordingly, the ISP
module of the TOC-L automatically acidifies 20
the sample and strips the CO 2 originating
from the TIC. 14

The excellent particle tolerance of the Signal[mV]
analyzers enables analysis of particle- 7
containing surface waters. Using the
automatic dilution function, multi-point
calibrations can be generated from a single 0
standard. In the investigation of unknown -2 0 5
surface waters or groundwater, one of the
samples may exceed the calibration range. In NPOC-Method
this case, the TOC Control-L software offers Acidification: 1,5%
an option for automatic dilution to bring the Sparge-time: 5 Minutes
sample back within the calibration range.
TOC-Concentration: 3,4 mg/l
RSD (3 Injections): 1,4%

■ Recommended analyzer / Configuration

- TOC-L CPH
