■ Calibration with automatic dilution
function
To create calibration curves, the dilution
function is activated via the wizard:

The core feature of the TOC-L series is the
ISP module (Integrated Sample
Pretreatment). The ISP module consists of an When filling the data of the calibration points,
8-port valve and a syringe with sparging gas the concentration of the standard solution
connector. In addition to acidification and (stock) is entered first, followed by the
sparging in the syringe, the system enables desired calibration curve point. The software
automated dilution. This allows for the wide calculates the required dilution factor:
measuring range, dilutes highly polluted
samples and enables the creation of dilution
series from a stock solution. The various
possibilities offered by the ISP module thus
reduce the time expenditure by the user.

Since fractional factors are allowed, it is

Fig. ISP-Module of TOC-L possible to create a 10-point calibration curve
series with equidistant concentration intervals from
one standard solution.
